Four Roll Crusher institutions and worksFour Roll Crusher is mainly composed of the main and auxiliary drive gearbox, chassis, chassis, crushing rollers, the main components of the gas-liquid buffer tank and motor. The main and auxiliary drive gear box and on the lower segment crusher by the clamp coupling rigid connection is formed integrally of a gear transmission. The motor is driven by the large and small pulley and V-belt drive shaft of the main gearbox, large pulley and the drive shaft connected device not overload safety pin, to ensure that the motor overload protection.
Raw coal through the feed inlet into the crusher machine chamber, entering under the action of gravity between the two on stage crushing rollers. The upper roller in the power driven rotating, and the role of the roller teeth and the cushioning cylinder on the crushing roller pressing force on the material to be crushed. The material after the primary crusher continue to fall under the action of gravity to the lower section between the crushing rollers, in the same working principle on the material broken again. Rule out the crushed material through the discharge opening. Roll broken main function is splitting the broken material particle size uniformity, less powder.
