AfriSam has enhanced its Rheebok Quarry operation with the installation of a high-capacity Sandvik CH430 cone crusher from Sandvik Rock Processing. The upgrade ensures reliable safe production with reduced maintenance and a lower carbon footprint.

Located near Malmesbury in the Western Cape, the granite quarry produces a range of materials, including aggregate stone, crusher sand, roadstone and ballast. According to Desmond Jacobs, AfriSam’s Senior Engineer for the Western Cape, this investment aligns with the company’s long-term capital strategy.

The decision to install the Sandvik CH430 was driven by key features such as its hydraulic Hydroset™ system and Automatic Setting Regulation (ASRi) system, both of which enhance performance and streamline maintenance. The Hydroset™ system enables precise automated closed-side setting adjustments, while the ASRi system continuously monitors and optimises crusher performance.

“We appreciate how the Sandvik CH430 minimises operator intervention allowing real-time adjustments to the closed-side setting,” says Jacobs. “This improves product size consistency and quality. The system also tracks key parameters like temperature and pressure, enabling proactive maintenance and reducing unexpected breakdowns.”

Jacobs notes that the new unit has already demonstrated its impact on product quality by reducing oversized material in the feed stream.

“Our initial assessments showed a dramatic reduction in oversize material being sent for secondary crushing,” he says. “This allows us to optimise throughput and potentially eliminate redundant processing steps in the future.”

A crucial factor in selecting the Sandvik CH430 was its compact footprint which closely matched the previous crusher. “As a brownfields project, we had to work within existing site constraints,” Jacobs explains. “Matching the footprint was essential as we had limited time for installation and could not accommodate extensive structural modifications.”

PC Kruger, Business Line Manager for Crushing Solutions at Sandvik Rock Processing, highlights the Sandvik Plant Designer platform which helped optimise the model selection process. Additionally, the energy-efficient crusher, powered by a 132 kW motor, aligns well with AfriSam’s specification, contributing to lower energy costs and reduced carbon emissions.

With a local office and warehouse in Cape Town, Sandvik Rock Processing ensures AfriSam receives prompt technical support, spare parts and plant audits whenever required.
