This system is designed for the pretreatment of bulk materials, ores, coal, geological samples, industrial raw materials, and waste products. It ensures the delivery of representative test samples required for precise chemical analysis.

Samples undergo primary crushing and are mixed through the drop between conveyors to enhance representativeness. The secondary conveyor then transports the material to a ten-station rotary divider. With adjustable belt and rotation speeds, the system adheres to industry standards to ensure every sub-sample accurately represents the original bulk material.
