Working Principle of Roll Crusher

Roll Crusher

The main structure of the wheel gearing is composed of fixed roll, movable roll, drive shaft, machine box, chassis, cover piece and long gear cover. The motive power of the machine comes from the V-belt pulley of the electromotor, and a pair of middle reduction gear will make the fixed roll rotate, and then a pair of long gear drive on the other side of the fixed roll will drive the movable roll, and the two rolls perform relative movement to squeeze the materials.

Roll crusher is suitable for the coarse and medium crushing of crisp bulk materials in cement, chemistry, power, mine, metallurgy, building material, refractory and coal mines. The feeding granularity of this machine is big and the discharging granularity is adjustable, and the compression strength of the materials to be crushed should be below 160 MPa. When using this machine to crush raw coal in coal industry, after deironing and edulcoration without gangue removing, the raw coal can be directly crushed, and the crushed materials have even granularity and low over crushing rate, thus simplifying the coal dressing process and reducing the investment and production cost. The most commonly used roll crusher are double roll crusher(double roller crusher) and toothed roll crusher.
