Product Details

Jaw plate is the most consumed, so we must take it in good quality when choosing, jaw plate life is an important indicator of good or bad quality. Jaw crusher body of work is fixed jaw and movable jaw formed consisting of the working chamber, fixed jaw and movable jaw are under enormous crushing force and the friction material, easy to wear out, in order to protect the jaw, hongxingly in the fixed jaw and movable jaw surface wear of the liner installation, also known as broken boards. Jaw plate surface is usually made of tooth, jaw plate angle of tooth peaks 90 ° ~ 120 °, its size has been broken by the nature of the materials and fragmentation may be. With the constant wear and tear of the tooth plate, the port of discharge gradually becomes larger, the products continue to thicken, need to be adjusted periodically in order to get qualified product size, the size of the discharge mouth. Adjustment method of discharging port has the following:

1. Gaskets regulation, a group that is put between the back rack of the rear wall of the rear thrust plate bearing seat gasket, increase or decrease the number of shims or change its thickness is needed to achieve the purpose of adjusting the discharge mouth. This method compact structure, reliable regulation, large and medium-sized jaw crusher and more with this regulation.

2. Wedge adjustment, with two wedge adjustment on the thrust plate between the back seat and rack, suitable for small crusher using.

Jaw crusher crushing action extrusion method using music, motor-driven belt and pulley, the eccentric shaft to move up and down jaw movement, when the movable jaw rises between toggle plate and moving jaw angle becomes larger, thus promoting the movable jaw close to the fixed jaw plate, while the material is squeezed, rubbing, grinding, etc. broken in multiple ways; when the movable jaw down, the elbow angle between the plate and moving jaw smaller, movable jaw plate in the bar, under the action of the spring leave t
