Craig Pedley, founder and CEO of Striker Crushing and Screening, shares how keeping things simple, rugged and operator-focused has set the Australian business apart from the competition.

When Craig Pedley started Striker Crushing and Screening in 1998, he did not have a corporate roadmap or a boardroom of advisors. What he did have was a passion for designing machines that made life easier for the operator.

“From day one, our philosophy has been simple. Build machines that are easy to operate, easy to maintain, and tough enough to handle remote Australia,” Craig said. “We’ve always designed equipment with the operator in mind and built it to last in remote Australia.”

Keeping it Real: Designed for
the Operator

Striker’s no-nonsense approach has earned it a loyal customer base both in Australia and worldwide.

Craig said being focused on designing machines that are tough, practical, and focused on the operator helped set Striker apart. These core values have shaped the business for over 25 years.

Striker’s equipment is built for ease of operation, ensuring operators can hit the ground running, and ease of maintenance, with simplicity that means less downtime. The commonality of parts keeps spare parts inventory and costs low for the customer.

A focus from day one was to design equipment with interchangeable components. This was important to the Striker team to help operators reduce spare parts inventory, lower costs, and streamline maintenance. Whether it’s jaw crushers, impact crushers, cone crushers, or screens, having parts that work seamlessly across the range means fewer headaches on-site and faster turnaround when maintenance is needed. This thoughtful approach simplifies operations and ensures greater up-time, keeping projects running efficiently and cost-effectively. It’s a practical solution built for real-world operators needing reliability without unnecessary complexity.

“On site, simplicity and reliability are hands down the most important things to our clients,” Craig said.

The Next Generation

Today, Craig’s daughter, Jordan Pedley, is leading the charge as the next generation of Striker. Energetic, driven, and proudly carrying on the family legacy, Jordan combines a fresh vision with the same hands-on, customer-first mindset that built the business.

“I grew up watching Dad build Striker from the ground up,” Jordan said. “One thing that’s always stuck with me is that listening to our customers drives a lot of what we do. While our innovation and design teams are amazing, the customer is the real expert.”

Jordan credits Striker’s agility and personal approach as key to its success.

“We’re big enough to deliver but small enough to care. Whether it’s our service team helping operators or the production team walking through the machine build in the factory with the customers, we’re responsive and hands-on. That’s something our customers value,” she said.

Alongside Jordan, Nicole Talbot, Striker’s chief operating officer, plays an integral role in driving the business forward. Over her 16 years with Striker, Nicole has grown into her role with the support of her colleagues and mentors.

“When I first started with Striker, I knew nothing about this type of equipment,” Nicole said.

“I spent a lot of time learning from some really influential people within this business. People like Ken Baudinette, Adam Quad, and Mark Mackey who are not only a wealth of knowledge on our equipment but on machinery across the board.”

A Greener Future

Striker is paving the way for a greener future with its E-Trac range, a line of electric mobile crushing and screening equipment designed to help customers meet sustainability goals without sacrificing performance.

“At Striker, innovation is at the heart of what we do,” Jordan said. “E-Trac was designed to reduce diesel consumption, lower emissions, and improve safety. All while maintaining the power and reliability Striker machines are known for. On top of that, our remote monitoring systems provide customers with real-time data on machine performance, empowering them to make more informed strategic decisions efficiently.”

Growing Capabilities, Stronger Support

Striker has invested heavily in its manufacturing capabilities, leading to a 150 per cent increase in capacity in Australia. This expansion ensures faster delivery, reduced lead times, and stronger customer support.

“Our goal for 2025 is to roll out more Australian-made tracked machines than we have in years,” Jordan said. “We’re also expanding spare parts manufacturing right here at home. That means less downtime and quicker solutions for our Aussie customers when they need it most.”

Built on Trust

At its heart, Striker is a business built on trust. Trust in the machines, trust in relationships, and trust in the team that makes it all happen.

“You can’t build a company on your own,” Craig said.

“It’s about the people, our team, our customers, and our suppliers. We’ve worked with some incredible people over the years, and every one of them has helped shape Striker into what it is today.”

For Jordan, stepping into the role comes with big shoes to fill, those of her father, Craig Pedley, whose passion and vision built Striker from the ground up. Her focus now is on balancing innovation and growth while staying true to the values that have defined Striker from the start.

“We’re here to make life easier for operators and businesses,” she said. “That’s what we’ve always done, and that’s what we’ll keep doing. There’s nothing better than hearing from a customer that one of our machines made their job easier, faster, or more cost-effective. That’s what keeps us going.”

As the founder of the business, Craig is looking forward to watching the business continue to grow.

“We’ve got a lot of knowledge that we can draw on in terms of how to do it right. It is something that I am pretty excited about, that there are people within our organisation who want to take this to the next step and put their own stamp on it.

“I look forward to watching it progress as they take the business to the next step.”

Share on FacebookShare on Twitter

The sand-washing range from Precisionscreen is made for Australian conditions with options for all types of operators and contractors.

Demand for natural or manufactured sand is rising in the Australian market, so having the right equipment is essential.

Precisionscreen has developed its sand-washing equipment range over several years to ensure it could help the smallest of sand producers to the larger players in the sector.

Jonny McMurtry, chief operating officer at Precisionscreen, told Quarry he believed there would likely be continual strong demand for the material.

There has been an increase in demand for sand washing equipment as I think there is increased demand for washed sand in the market,” he said.

“As the volume of infrastructure continues to be there and climb, the requirement for sand isn’t going to go away.”

The market for washed sand and manufactured sand is becoming more diverse as quarries explore how they can use the material to either expand their offering to the market or add new revenue streams.

Original equipment manufacturers like Brisbane-based Precisionscreen have developed a wide range of sand-washing equipment to suit specific applications and help customers take advantage of the growing demand. In one case, Precisionscreen worked with Victorian-based construction materials supplier site to create a sand-washing solution for their manufactured sand application. The company has employed the use of a sand screw from Precisionscreen to create a manufactured sand using washed crusher dust.

“Our sand washing equipment has been developed over a number of years and we offer different machines for different applications or customer price ranges or throughputs,” McMurtry said.

Precisionscreen has built out its range of sand washing equipment to provide solutions for customers from the first stage of washing to the final stage. The company manufactures all its sand washing equipment at its headquarters in Wacol, Brisbane which gives it the distinction of being Australian made.

The company’s adaptable wash kits have a range of customisable features to tailor the kit to the customer’s specific application. The Precisionscreen wash kit can range from single deck to two or three-deck kits which are built on the screen box.

Each deck has multiple spray bars with several spray nozzles to rinse the product being processed.

Operators can finely control the individual gate valves to each bar which provides enhanced control and excellent washing coverage.

“The wash kits as part of our screen boxes are probably the first step for sand washing,” McMurtry said.

“We sold quite a few of those this year, predominantly for sand washing but even washing pebbles or rinsing different products to remove dust has been in demand.”

Precisionscreen Sandscrew has also been in demand from customers across Australia due to its versatility. It can work alongside Precisionscreen’s wash kits or other wash plants to help dewater and classify sand products.

The sand screw has a hydraulic drive and features a mobile-wheeled axle as well as an adjustable overflow weir. The Sandscrew can be operated off the Precisionscreen’s screening plant powerpack.

The spiral screw helps separate heavier particles as they sink to the bottom of the trough after being dragged through the trough by the spiral screw. Dewatering occurs throughout the trough until the finished product is discharged via a chute.

“Our Sandscrews have been quite a hit just due to the adaptability. It can work with existing screening plants or existing applications if needs be. We’re one of the few manufacturers that makes our sand screws semi-mobile so it can couple up with existing systems if needed,” McMurtry said.

“The sand screw is probably on the lower end with throughput and cleanliness of sand but it has performed very well [in creating] a manufactured sand where it is quite suitable and economical for that type of application.”

Precisionscreen has also created a modular sand washing plant which combines a galvanised 10×5 two-deck wash screen with a SRD180 bucket wheel dewaterer and a fines recovery pod to create a one-stop solution for sand producers.

It allows operators to create up to three different sand fractions and accept material from a dry screening process via conveyor belt or cyclone mounted above the screen. The SRD180 bucket wheel dewaterer collects sand particles from slurry materials in a wet screening process with its primary responsibility being to pick up heavier particles of sand as they sink to the bottom of the tank. It can manufacture coarse and fine grade sands simultaneously. It features a submerged back screw which helps float off unwanted silts while its large water overflow area and polyurethane bucket inserts provide a sizeable dewatering capacity.

The FRP has a 250mm cyclone on-board, discharging heavy particle sand onto the high-frequency dewatering screen for draining. The screen helps remove unwanted materials, excess water or organic materials from the sand material. The cyclone and screen are hydraulically driven and designed to work with Precisionscreen’s washing plants.

McMurtry said the SRD and FRP had benefits even as standalone products for Australian operators.

“The SRD180 or the FRP gives a greater throughput and a cleanliness of the sand as well and that’s where it comes into its own.

“If you have a high silt content and you need to float off a lot of that bottom end product in that super fine sand, that’s when the likes of the SRD or FRP comes into its own,” he said.

“If a customer has water restrictions or low access to water that is where the FRP can allow any residual water to be taken off your sand product quite quickly and easily. Or it can use the cyclone to take out the super fine sand to recycle that water quickly.” •

Following a strong bid from the South Australian Government and key mining stakeholders, the Asia-Pacific International Mining Exhibition (AIMEX) will be moving to Adelaide in 2025.

The agreement will see AIMEX call Adelaide home for the next 10 years, strengthening South Australia as Asia-Pacific’s fastest growing modern mining market.

AIMEX was acquired by Prime Creative Media in May 2024. As Australia’s longest running mining show, AIMEX has a history of supporting the latest trends and developments in the industry.

This move to South Australia represents the next phase in the regional resources sector, with the state leading the charge in responsible exploration to unlock minerals. It has also been driving the investigation of solutions for decarbonised steelmaking, efforts that are critical to the future of infrastructure development.

“We’re working to keep AIMEX’s reputation as a key event for the Asia-Pacific region,” Prime Creative Media general manager of events Siobhan Rocks said.

“We knew we needed to do something big to attract key players in the industry. When the mining industry asked us to come to Adelaide, we thought this change of location was the best way to serve this important sector.”

South Australian Premier Peter Malinauskas said with South Australia’s natural advantages and ingenuity, the state has the potential to lead the world in decarbonisation of critical minerals, including green steel and copper.

“We have a compelling story to tell, and AIMEX being hosted in Adelaide for the next decade provides a strong platform to do just that,” Malinauskas said.

“This exhibition will attract thousands of mining delegates from around Australia and the world to Adelaide every two years, delivering a significant boost to South Australia’s visitor economy.”

Business Events Adelaide chief executive officer (CEO) Damien Kitto said AIMEX is a significant win for Adelaide, one which will generate more than $250 million for the South Australian economy over the next 10 years.

“We are proud to be entrusted with this long running business event, and it demonstrates that Adelaide is increasingly being viewed as a modern powerhouse in sustainable energy generation,” Kitto said.

“Business Events Adelaide shares Prime Creative Media’s ambition of making AIMEX the world’s largest mining event.”

Mineral Resources (MinRes) will transition its Bald Hill lithium mine in Western Australia into care and maintenance amid cyclically low lithium prices.

The major miner acquired Bald Hill for $260 million in late 2023 to ensure the operation’s profits stay in Australia.

MinRes will now transition the operation into care and maintenance to preserve the mine’s cash and the spodumene orebody’s value for when global lithium market conditions improve.

During care and maintenance, MinRes will continue to optimise mine plans, scale and operating structure ahead of any future restart.

The company will cease Bald Hill’s mining and mobile maintenance operations on November 13 and will temporarily cease operations at the spodumene concentrate plant and accommodation village by early December.

The final spodumene concentrate shipment from the mine is also expected to be sold in December.

Approximately 300 employees will be impacted by the transition, with all Bald Hill employees to be prioritised for redeployment across MinRes’ other WA operations. Where redeployment opportunities cannot be found, a redundancy process will be followed.

A team of about 10 MinRes employees will remain on site at Bald Hill to manage the scaling down of lithium production, as well as care and maintenance activities.

“Bald Hill is a significant value opportunity for MinRes once conditions in the lithium market improve,” MinRes managing director Chris Ellison said.

“Placing Bald Hill on care and maintenance is a prudent decision but one not made lightly. The decision aligns with the work we have done across the company in recent months to reduce costs.”

Despite the temporary shutdown, MinRes has increased Bald Hill’s mineral resource by 168 per cent. The mineral resource now stands at 58.1 million tonnes at 0.94 per cent lithium oxide.

“The significant upgrade to the mineral resources statement is evidence that Bald Hill is a high-quality asset with a long-term future,” Ellison said.

“We will continue to monitor lithium prices and site operating costs with a view to recommencing operations once conditions improve.”

Newmont has entered into a definitive agreement to sell its Akyem gold mine in Ghana to Zijin Mining Group for up to $US1 billion ($1.5 billion).

This deal marks a significant step in Newmont’s strategy to focus on its Tier 1 assets, which are expected to drive long-term growth and shareholder value.

The transaction includes a cash consideration of $US900 million upon closing, with an additional $US100 million contingent on certain conditions being met.

Proceeds from the sale will be used to bolster Newmont’s balance sheet and return capital to shareholders.

“The sale of Akyem represents continued progress on the non-core asset divestiture program announced in February, supporting our focus on the Tier 1 assets in Newmont’s portfolio that will drive sustainable growth and the return of capital to shareholders,” Newmont’s president and chief executive officer Tom Palmer said.

“We believe the proposed transaction results in the greatest overall value for Newmont shareholders and is the best strategic fit for Akyem.

“We are confident that Akyem will continue to thrive under new ownership with long-term benefits for local stakeholders and surrounding communities.”

Palmer said the successful completion of this transaction will strengthen Ghana as a favourable mining jurisdiction, with Newmont committed to supporting the growth and development of the region which includes the development of Ahafo North.

“In line with President Afuko-Addo’s address in February, we ensured that our robust divestment process provided equal opportunity for all potential buyers, Ghanaian and international, to participate,” Newmont managing director for Africa Rahman Amoadu said.

“Additionally, we have included the minerals income investment fund (MIIF) in the process in preparation of their potential investment in Akyem to further Ghanaian interest in the mine.”

The transaction is expected to close in the fourth quarter of 2024, pending regulatory approvals.

With the Akyem divestment, Newmont does not anticipate a material impact on its 2024 outlook and remains committed to its investments in Ghana, including between $950 million–1.05 billion in development capital for Ahafo North.

Sharing the load in Esperance

Staff Writer

The Port of Esperance. Image: Southern Ports

Treotham worked with Southern Ports to deliver boosted efficiency to its Esperance ship loader.

Western Australia’s Port of Esperance is a busy place, with more than 13 million tonnes of trade passing through the port last year.

Esperance is a well-traversed path for Australian miners, with iron ore and spodumene joining nickel as the port’s major exports.

When dealing with this kind of tonnage, even the slightest inefficiencies can have an impact on trade. That’s why the Port of Esperance’s custodian, Southern Ports, looks for solutions it can count on to reduce inefficiencies.

Treotham national sales manager John Sharp was brought in by Southern Ports to design a solution that would keep the port running smoothly while offering cost savings and boosting worker safety.

“I had been to the site a few times and saw the opportunities to improve the system that supplied power to the ship loader,” Sharp told Australian Mining.

“Treotham’s priority is to develop solutions that work, so we put together a new custom-designed system that would get the loader running more efficiently.”

The system, called a belt tripper, was incorporated onto a conveyor in order to “trip” the material off at specified locations between the terminal pulleys. The material is then discharged onto another conveyor that loads the Port of Esperance’s ship-loader.

A belt tripper can be in a fixed position or travel continuously at a constant speed for layered stacking.

In the port’s case, as the ship-loader was moving, it caused the energy chain to move from where it should be, disrupting the ship-loading operation and requiring it to be stopped until the energy chain was put back in its trough.

Treotham supplied Southern Ports with a marine-grade aluminium guide trough, energy chain and cable management system with anti-lift protection used to power the loader.

Sharp said the biggest challenge was determining where the energy chain should go.

“We ultimately decided to put it in the gallery, meaning we could simply put brackets on the existing conveyor structure, making installation quicker and more efficient than alternative locations,” he said.

Treotham turned to long-time partner igus for a 105m energy chain that was used to get the power needed for the system.

When igus first began developing its energy chain solutions, it saw great potential in an area that it felt had been somewhat overlooked.

Working from its extensive testing facilities in Germany, igus uses different construction methods within the cable materials to find those that work best. Its portfolio now contains tens of thousands of chains divided up into family groups, with the E4 family known as the most ‘heavy duty’ solution.

A key feature of these chains is their flexibility.

“For the Port of Esperance’s solution we used water hoses, fibre optics and high-voltage igus Chainflex cables,” Sharp said. “If you think about the market for high-voltage cables, they’re around on every street corner at a transformer, but they’re not flexible, so they’re for static installation.

“Then when you look at high-voltage cables for continuous motion, not many companies actually produce this; it’s quite a feat of engineering to build such a high-voltage cable designed to continually bend.”

Sharp said using the igus energy chains for the Esperance project led to something of an eye-opening development.

“When the chains are moulded, tools can wear out over time,” he said. “That means it’s possible to build a chain that’s no longer straight because of the different lengths of each side part.

“What igus did with the E4 was make left and right sides interchangeable, so there’s just one tool.

“This streamlines the stock holding, and also makes for a better-quality product.”

igus energy chains are designed to withstand extreme push and pull forces, a critical element in bulk material handling.

Such is the reliance on the energy chain’s durability, most systems integrating them don’t shut down until a ‘catastrophic’ failure. When a failure does reach a catastrophic level, the downtime caused by damage to the chain or the system can be excessive.

That’s why Treotham’s Esperance solution included a ‘push–pull detection system’ (PPDS) that triggers a signal to operators when forces on the chain are becoming too great.

“The PPDS is a mounted sensor that measures force continually,” Sharp said. “It can be configured to meet the needs of the operator when excessive force is detected, whether that be a warning or an automatic controlled stop.”

The system’s safety features were put to the test when a ladder was left against the new system.

“The ladder hit the chain, which proceeded to stop completely rather than continue and risk causing a catastrophic failure,” Sharp said. “The customer was extremely pleased to not have the damage and downtime that would have ensued.”

Treotham’s expertise allowed Southern Ports to explore a unique solution to the issues it was facing with its ship-loader.

The end result delivered not only improvements to the tripper but also reduced installation costs in a collaboration between Treotham personnel and Southern Ports’ own in-house technicians.

“It was a huge benefit to be on the ground, implementing the Esperance solution in-person,” Sharp said. “With a team of two fitters and two electricians from Southern Ports, we fitted the system in five days. I’ve seen similar projects that were sub-contracted out and snowballed into taking more than 12 months.

“It’s always fun working with a customer that can operate in-house for these kinds of solutions and bring in our team to create a group of like-minded experts to get the job done.”
