Soil-Stone Separator

Roller Soil-Stone Separator — Engineering-Grade Material Separation, Rethought

The roller soil-stone separator sets a technical benchmark in construction & demolition waste processing and mining with its rotary screening principle. Multiple counter-rotating alloy rollers, set with precisely calculated gaps and speed differentials, separate soil from stone in mixed material with high efficiency. Precision bearings combined with variable-frequency drive keep the process stable and exact, raising separation efficiency by more than 35% over conventional equipment.

We redesigned the machine structure: one-piece cast roller supports with dynamic balancing reduce vibration transfer at speed. Intelligent gap adjustment optimizes working parameters to the material, and the self-cleaning rollers solve the industry-wide problem of sticky material wrapping. A stepped roller layout lets gravity and mechanical force work together, making separation smoother and cutting energy use by up to 25%.

As demand for resource recovery keeps growing worldwide, our roller soil-stone separators serve as core equipment on engineering projects. Every machine passes a strict 72-hour full-load test before delivery, with a complete digital quality file. That attention to process detail has built a professional reputation in major infrastructure and mine rehabilitation projects — delivering higher separation precision and operating value.
