A tin mining operation in a region of the Democratic Republic of Congo faced persistent challenges with its existing crushing setup. The site suffered from unstable power supply, limited access to spare parts, and a shortage of skilled maintenance personnel. The old equipment frequently broke down, causing costly delays and inconsistent feed for downstream processing.

After comparing several suppliers, Mr. Liu chose Huashengming Heavy Industry for a robust and easy‑to‑maintain solution. Our technical team recommended a two‑stage crushing train: a PE‑150×250 jaw crusher for primary reduction, followed by a 2PGT400×250 spring‑type double‑roll crusher for secondary fine crushing. The jaw crusher reduces run‑of‑mine ore (up to 150mm) to below 30mm, while the roll crusher further breaks it down to a uniform 2‑8mm product, ideal for tin gravity separation.

The spring roll crusher was deliberately selected over hydraulic models for this project. Its mechanical spring adjustment is simpler, more forgiving of voltage fluctuations, and easier to repair on‑site with basic tools. The 2PGT400×250 delivers a capacity of 2‑20 tonnes per hour, perfectly matching the mine’s moderate throughput. Its two rolls are made of high‑chromium alloy, providing excellent wear resistance against the abrasive tin ore – a critical factor that extends service life and reduces replacement frequency.

Key advantages of this setup include: (1) compact footprint, fitting into the mine’s limited space; (2) low energy consumption, crucial for a site with unreliable power; (3) spring‑loaded gap adjustment, allowing operators to fine‑tune product size without complex hydraulics; (4) minimal over‑crushing, preserving valuable tin particles; and (5) straightforward maintenance – worn roll shells can be replaced individually without discarding the entire roll body.

Mr. Liu expressed strong satisfaction with Huashengming’s service, from initial design consultation to manufacturing and shipping. He particularly appreciated the clear documentation and remote guidance for installation and startup. The equipment is now packed and ready for shipment to the port, and Mr. Liu expects a significant improvement in production efficiency and a reduction in unplanned downtime.

This order reinforces Huashengming’s reputation in the African mining sector. With nearly 30 years of experience, we continue to supply tailored, factory‑direct crushing solutions for tin, gold, iron ore, quartz, and many other materials, exporting to clients worldwide.
