When the non-crushed materials (such as iron, steel balls, etc.) enter the jaw crusher cavity, in order to protect the important parts from damage,therefore we adopt thrust plate as the insurance component of the crusher.The thrust plate individually adopts cast iron to cast overall parts, in which open a slot or certain holes to decline the intensity of its cross-section, and then link up with screws, and composed of a combination of thrust plate. But when non-crushed materials enter the crushing chamber, equipment will generate overload scene,if the big crushing force is sent to the thrust plate, which will cut the lead to a break or a combination of thrust plate screw, machine will stop work, it plays the role of insurance.

Henan Hongxing is specialized in the producing of jaw crusher,impact crusher, cone crusher, industrial milling machine, and vibrating screen, dust collector equipment, to succeed in a lot of mining and processing to use. This design principle is not only very suitable, but simple holding, low costs of exchanging insurance parts, easy to operate, which is also extremely good without damage. The jaw crusher is coarse crushing equipment for ores and other hard materials, and it is characterized by big crushing ratio, high yield, uniform particle size, simple structure, easy maintenance and low production costs. Therefore, to reduce the resistance to axial movement of material, they should reduce the coefficient of friction of the bottom of the barrel so that the bottom can be smooth as far as possible and increase the coefficient of friction of the side wall of the cylinder to suppress the effect of centrifugal force.

The movable jaw plate makes direct contact with the materials when the jaw crusher is working, and thus it often suffers great load.In the process that sending materials into the opening mouth of jaw crusher, it may be difficult to crush materials of a special firm stones or iron objects. If inappropriate piece of insurance in a timely manner prohibits this from happening, then the hard materials in the crushing chamber will be crushed deformity or even directly impede the operation of the equipment, resulting in downtime review. And if there is insurance ensuring adequate supplies, which will greatly promote the proactive moderation of crusher equipment and production lines.
