Jaw crusher is widely used in stone factory, mining and construction industry. Jaw plate is the core of jaw crusher. When crushing materials, crushing teeth are squeezed, grinded and impacted by materials and bear huge loads. The direct consequence is that the jaw plate is prone to wear. The wear of crushing teeth will lead to the increase of power consumption of crushing station. If it is serious, it will lead to the shutdown of equipment. Frequent replacement of jaw plate will also affect the benefit. So what causes jaw plate wear, and how can we avoid it?
1, material hardness
The hardness of materials is the primary factor of jaw plate wear. Under certain other conditions, the higher the hardness of materials is, the easier it is to form wear on the surface of jaw plate, which causes furrow to accelerate the wear of jaw plate.
2. Jaw plate material
The strength of the jaw plate itself, the material of the jaw plate determines the wear resistance of the jaw plate, the wear resistance of the jaw plate determines the service life of the jaw plate. Therefore, the choice of jaw plate quality is also an important influence on the wear of jaw plate. So the jaw plate must choose high hardness, wear resistance, resistance to strong materials, commonly used is high manganese steel;
3. Adjustment of jaw breaking equipment
The jaw plate and the machine surface contact is not smooth will also accelerate the jaw plate wear, in the installation of the jaw plate, must be installed, fixed tightly, so that the surface contact with the machine is smooth; Eccentric shaft speed is too fast, has broken the material too late to exclude, resulting in crushing chamber blockage, jaw plate wear; The Angle between movable jaw plate and fixed jaw plate is too large, exceeding the normal range;
