How jaw crusher to ensure the safety and regulation of the discharge?
Pusher plate jaw crusher is also known as switches, in addition to transmitting the power to move the jaw plate back and forth, but it also has a security role that insurance, to change its length may also play a role in the regulation of the discharge mouth.
When there is material that can not be crushed in the cavity (eg, iron balls, iron, etc.) to protect the equipment against damage, the thrust plate is used as a grinder insurance return units. The pusher plate is usually back with the cast as a whole, an open slot or a number of holes in this section to reduce its intensity, it can also have two parties, and then use screws to connect together to form a thrust plate combination. When things can not be broken in the crushing chamber, equipment surplus rose to great power broke the thrust plate and the pressure plate to break or cause a combination of the screw pusher plate off The machine does not work, but it can play a role of insurance.
As the constant wear and tear of the plate, the discharge mouth gradually become larger, the production yield become larger and thicker in order to obtain a qualified product size, need to periodically adjust the size discharge from the mouth. Methods for adjusting the discharge operation are mainly the following two:
(1) common adjustment, which is, after the thrust bearing between the posterior wall of the rear rack and put a carpet cushion or change the number of its thickness, we can achieve the purpose of regulating the mouth of discharge. This method is compact, adjustable, reliable, large, medium or large jaw crusher to the use of this method of adjustment.
(2) Adjust the angle, the thrust plate is placed between the seat and two rear adjustment rack corner, which is appropriate for jaw crusher small.
