Roll crusher could be applied in cement, chemicals, power, metallurgy, building materials, refractory industries to crush medium-hard materials, such as limestone, slag, coke, coal and other materials for intermediate and fine grinding operation.

The crushing equipment could be divided into single roller and double roller according to the number of the roller-cylinder. Single roll crushers are composed of rotating rollers and curved jaw plates. Materials are crushed by squeeze, impact and split. The toothed lining plate is installed on the roll core by the screw bolt, the lining plate could be replaced after abrasion. One end of the jaw plate is hanged on the shaft, the mandrel surface is lined with wear-resistant lining plate.

The jaw plates are pulled to rollers through two levers and the springs pressure of the machine frame. Thus the jaw plates and rollers have a certain distance, and the roller bearings are mounted on the bearing of the machine frame walls. Single roll crushers are suitable for the materials’ coarse grinding, which has a larger inlet, whose surface has crushing gear rack, more suitable for crushing low hardness and soft materials. Dual stick crusher consists of the fixed and mobile crushing rollers, two opposite rotating cylindrical rollers.

Materials are added from the top of the roll crushers, which is pulled into the gap between the two rollers due to the friction, then broken by squeezing. The crushed material is discharged by gravity.

Roll crushers’ working parts mainly include the following components: roller, roller support, bearings, clamping and adjusting devices and driving devices. Its structure is simple, easy to manufacture, suitable for crushing medium and low hardness, brittle, cohesive and soft materials. It is used to break clay, coal, and other mixed materials.

The roll crushers produced by Zhengzhou mining machinery Co., Ltd inherit 50 years of technical advantages, continuously improved and innovated, not having low power consumption, high quality. It is the ideal product for rough and intermediate crushing.
