Jaw crusher

Jaw crusher is a crushing machine composed of a moving jaw and a static jaw. It is mainly used for coarse and medium crushing of various ores and rocks. It is widely used in mining, building materials, roads, railways and other industries.

The crusher mainly consists of the body, eccentric shaft, static jaw, movable jaw, adjustment device, transmission device, power part, etc.
The body adopts two structural forms, integral casting type and high-quality steel plate welding type, and the integral box body is composed of multiple reinforcing ribs. The eccentric shaft is made of high-quality carbon steel and turned into eccentricity. Bearings are installed at both ends and fastened to the frame. The movable jaw has two forms of integral casting and welding structure. A pair of ZGMn13 cast jaw plates are fixed on the movable jaw and the frame. When the motor drives the pulley and drives the movable jaw to move back and forth through the eccentric shaft, the jaw plate crushes the material to achieve the purpose of crushing.
The eccentric shaft is equipped with a pulley, and the power of the motor is transmitted through the V-belt to make the machine work. A flywheel is installed at the other end, which can accumulate power and increase the crushing force. The large machine is also cast with an eccentric block, so that when the machine runs to the crushing point, the kinetic energy accumulated in the eccentric block is released to increase the crushing force.
The adjustment device is mainly used to adjust the size of the discharge opening, which is proportional to the output. By changing the position of the support plate, the gap of the discharge opening can be adjusted. The adjustment device of the small machine for laboratory use is installed at the rear of the machine. Loosen the knurled bolt and turn the hand wheel to adjust. The particle size of the material discharged clockwise is small, and the particle size is large. Large models are adjusted by adding and subtracting multi-layer pads. The support plate system can not only adjust the gap, but also play a role of insurance. When the feed is overloaded or encounters iron, it will bend or break, causing the machine to stop working and protecting other parts from damage. In order to protect the frame for long-term use, guard plates are installed on both sides of the frame to protect the machine body from wear.
