In sand production lines, the double-roll crusher functions as a sand-making machine, offering advantages such as no wear parts, low maintenance costs, adjustable sand particle size, high yield rate, and excellent sand particle shape. It is widely used in the sand-making industry.



This equipment is driven by the motor(2), through the belt(1) drive the hollow shaft(9) to make the inner drum(5) working rotary in a high speed. The back wash water will be flowed from the ratory valve(3) to hollow draft(9), then the back wash water will be fed to the outer drum(6) and inner drum(5). (Pressure is under 0.03—0.06Mpa). The ore will be fed to the inner drum(5) by the feeding tube(4). The ore is under centrifugal fore to separate the material. The ore with heavier density will be stayed in the inner drum(5), the lighter ore will be flowed from the tailing ore tank(7). When the equipment stops, the concentrated ore will be discharged from the concentrated ore discharge(8).
