Schlam’ s Hercules milestone
Just ahead of bauma, Schlam announced the production of the 100th Hercules mining truck bed at its manufacturing facility in Longyan, Fujian Province, China.
The production milestone was made possible thanks to collaboration with Longyan Ruihua Tongyong Machinery Co Ltd.
Schlam recently announced the production of the 100th Hercules mining truck bed at its manufacturing facility in Longyan, Fujian Province, China
Since the first Hercules mining truck bed was built in Australia in 2003, the Hercules bed has been deployed across diverse mining environments – from Australia’ s deserts to Kazakhstan’ s plains – consistently enhancing payload efficiency and productivity, Schlam says.
With over 2,500 truck beds produced to date – primarily in Australia – the growing global demand for Hercules has also driven Schlam’ s strategic expansion into international markets. All Hercules truck beds manufactured in China are produced by Longyan Ruihua Tongyong Machinery Co Ltd at a state-of-the-art facility.
Schlam adds:“ This strategic partnership allows mining operations across Asia, Africa and beyond to access Schlam’ s industryleading products from a facility positioned closer to key mining regions, while maintaining world-class standards in quality, innovation and efficiency.”
To commemorate this significant milestone, a celebration event was held on March 28, 2025, at the Longyan Ruihua Tongyong Machinery facility, with guests including government officials, key customers and suppliers.
Molycop doubles Cilegon SAG ball capacity
In the plant space, Molycop recently strengthened its operations in Indonesia with the commissioning of a new SAG ball production line at its Cilegon facility.
This expansion, coupled with the acquisition of a state-of-the-art cast high chrome plant in Cikande, marks a significant milestone in the company’ s efforts to meet the growing demands of the Southeast Asian mining industry with efficiency and reliability, it says.
With these advancements, Molycop says it enhances its ability to provide high-quality grinding media solutions for its customers and strengthens its position as a leader in grinding media manufacturing in Indonesia and in the wider region.
The Cilegon plant has been a key part of Molycop’ s Indonesia operations for over 25 years. Initially set up to serve the local market, it has now been upgraded to meet the rising demands of the broader Southeast Asian mining sector. The new SAG ball production line at Cilegon doubles the plant’ s production capacity from 50,000 t / y to 120,000 t / y. This expansion significantly improves the plant’ s ability to produce high-quality grinding media for the mineral processing industry.
Keith Ritchie, General Manager, Molycop Indonesia, said:“ This development significantly enhances our ability to deliver both forged and cast grinding media directly from within the region, reducing lead times and improving supply chain efficiency.”
At the heart of Cilegon’ s advanced technology is a heat treatment facility that, the company says, simultaneously optimises NG SAG abrasion resistance and toughness to maximise performance even in the most demanding mill environments. As well as featuring robust inline processes, the production line offers flexible product switching capabilities to allow for easy scaling up of specific product output as required.
The newly established cast high chrome plant in Cikande, the first to be 100 % Molycop-owned, adds another layer to Molycop’ s capabilities. The facility produces cast high chrome balls and cylpebs, two types of grinding media known for their high abrasion resistance and durability.
Za’ iimatul Husnaa Muharromiyya, Molycop Business Development Manager, said:“ Both the new SAG ball line and the cast high chrome plant are equipped with multi-layered heat treatment processes and quality control facilities. This ensures that the grinding media we produce are of the highest standard, with consistent hardness, impact resistance and durability. Our customers benefit from reliable products that perform consistently in demanding milling conditions.”
Salyo Kahar Dikdoyo, Head of Commercial and Business Development, said:“ Molycop can now produce a wider range of sizes and compositions, providing customers with more options tailored to specific milling needs. This flexibility allows customers to select the most suitable grinding media for their operational conditions, which can lead to cost savings and improved grinding performance. The increased production capacity at Molycop’ s plants means our customers benefit from enhanced supply reliability, shorter lead times and access to the latest innovations in grinding media.”
The opening of the new SAG ball production line and acquisition of the cast high chrome plant at Cikande represent a strategic step forward for Molycop in Indonesia. By investing in advanced technologies, expanding production capacity and focusing on local manufacturing, Molycop says it has reinforced its reputation as a leader in grinding media solutions.
Optimising mantle profiles for gyratory crushers
The use of a new conical mantle design that leverages ME Elecmetal’ s proprietary manganese steel alloy is showing promise at a large copper concentrator, a new case study has shown.
This concentrator, which operates a 60”× 109” primary gyratory crusher, was experiencing challenges maintaining a
