Structure and Working Principle of Single Roll Crusher

Single roll crusher is one type of roll crusher, which is also called jaw roller crusher. It is suitable for crushing medium hard or soft materials such as limestone, stereoplasm clay and coal briquette. When the materials to be crushed are sticky and wet, the crushing effect of this machine is even better than that of the jaw crusher and cone crusher. Compared with jaw crusher or cone crusher, its performance and compact structure all have advantages. Next the experts of Hongxing Machinery will give a detailed explanation of the structure and working principle of the single roll crusher.

The outside surface of the roller and the inside curved surface of the jaw plate hanging on the central axle form the crushing chamber, and there is a supporting seat on the bottom of the jaw plate. The crushing chamber is composed of a rotating roller and a jaw plate. The toothed roll bushing is installed on the roll core with double-screw bolts, and the tooth tips sticks out like an olecranon, and the roller shell can be changed after being abraded. The jaw plate hangs on the central axle, and on the inside surface of the jaw plate, there is anti-abrasion lining board. With the help of the pressure of the spring pressed against on the machine frame, the jaw plate is kept some distance from the rollers with two tension rods. The roll axle is installed on the bearing of the two side walls of the machine.

When the single roll crusher works, under the friction force of the rollers and the materials, the materials fed between the two rollers will stick on the rollers with the rotation of the rollers and then are brought into the crushing chamber between the two rollers, and then are crushed and finally discharged out from the bottom. If some materials that cannot be crushed fall into the crushing chamber, the spring will be compressed, so that the jaw plate will go away from the rollers, thus increasing the discharging mouth to discharge the materials, and in the way, the crusher will be protected from being damaged. Flywheels are installed on the roll axle of the crusher to balance the kinetic energy of the crusher.

In addition, on the outside surface of the rolls, there are crushing racks with different heights. When big-sized materials are fed, the high rack will vise and crush them in a splitting and impacting manner, and then the crushed materials will fall to the low rack for further crushing, and finally the fine materials will be discharged out from the bottom of the machine.
