The problem of low productivity of jaw crusher is a common concern of users and manufacturers. This is mainly because the machine maintenance is not in place or the operator does not understand the machine, so how to improve the productivity of the jaw crusher, Xiaobian summarized the following points.

　　1. Dynamic horizontal operation. The horizontal stroke of the jaw has a * influence on the productivity of the jaw crusher. The low horizontal travel of the discharge will reduce productivity. On the contrary, horizontal stroke will increase the productivity of the machine, but not too much, otherwise too much material will be discharged. The crushing force increases dramatically, * to overloading and damaging the machine. The dimensions and operation should be reasonable.

　　2, pay attention to the maintenance of the machine. In the process of processing, the jaw crusher should be lubricated and maintained in time to ensure the long-term normal operation of the machine, such as: lubrication of lubrication parts, cleaning of the machine; Regular maintenance.

　　3. The size of the filling angle. It can be said that the angle of the machine tool fixture directly affects the production efficiency. Angled assembly reduces the crushing chamber, but with it reduces productivity. Small angle fixtures increase productivity.

　　4. Improve wear-resistant parts and reduce wear. For example, the efficiency of slabs that replace the original high-manganese steel material with medium-carbon low-alloy cast steel varies *ly. Medium carbon low alloy cast steel material is a widely used wear-resistant material, mainly due to high hardness, with appropriate toughness, can resist the cutting action of the material and fatigue peeling caused by repeated extrusion of the material, so as to show good wear resistance.

　　5. Improve the level of automatics. Such as jaw crusher automatic level improvement and overload protection; The same automatic adjustment and lubrication can achieve an increase in the level of automation and increase the productivity of the machine.
