What is Cobblestone sand making machine

The cobblestone sand making machine is a specialized equipment that mainly uses cobblestones to produce sand and stone materials for construction. The cobblestone sand making machine is another breakthrough in the field of sand and gravel aggregate production equipment manufacturing. This equipment uses two motors to drive two pairs of roller shafts to squeeze and grind materials.The roller crusher is mainly used for fine crushing operations with raw materials smaller than 80mm and finished product particle size requirements of 50mesh-20mm.

Working Principle

The cobblestone sand making machine operates through rollers. The cobblestone put into the machine through the inlet, are crushed by the squeezing between the rollers. The discharge size can be controlled by adjusting the gap between the two rollers. If the gap becomes larger, the discharged size becomes larger. While the gap becomes smaller by compressing spring, the discharge size also becomes smaller.
