In material crushing, especially in sand and gravel aggregate production equipment, crushing equipment is very important. There are many types of crushing equipment. Jaw crusher is a very widely used equipment. It is used for the * stage of crushing, for primary crushing, and for coarse crushing of large pieces of materials.

　　The working principle of jaw crusher is not complicated. The motor drives the pulley through the belt, and the eccentric shaft makes the movable jaw move up and down to squeeze and crush the material. When the movable jaw rises, the angle between the toggle plate and the movable jaw becomes larger, thereby pushing the movable jaw plate to approach the fixed jaw plate, and the material is squeezed and crushed at the same time; when the movable jaw goes down, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and spring. At this time, the crushed material is discharged from the lower opening of the crushing chamber. As the motor rotates continuously, the movable jaw of the crusher moves periodically to crush and discharge materials, realizing batch production. The content of fine powder and dust in the crushing work is relatively low, and the impact on the environment is also low.

　　The scope of use of jaw crusher is extremely wide. Common materials such as granite and basalt are not only hard but also highly abrasive. They are not suitable for crushing with hammer crushers or impact crushers. Gyratory crushers are complex to install and debug and have high cost. Jaw crushers have become a common choice, with high cost * and simple maintenance. Jaw crushers are suitable for crushing various soft and hard materials. Common use areas include mining, construction solid waste recycling, pre-crushing under mines, etc., with significant crushing effects. In addition, in addition to being used in factories, jaw crushers are also installed in large quantities on mobile stations.

　　Jaw crushers are the * step in crushing. The production of jaw crushers is directly related to the downstream medium and fine crushing. It is important to choose the right equipment, and necessary maintenance during use is also indispensable, so that you can go steady and far.
