As we all know, jaw crusher discharge mouth (row mouth) is mine according to the needs of user can be adjusted for qualified product material size. And also at first, we must konw the knowledge of jaw crusher thrust board.

The jaw crusher thrust board, also called cubits board, in addition to transfer power to and fro dynamic jaw plate do outside, but also has a safety insurance effect, changing its length also can rise to adjust the role of ore mouth platoon.

First we must be clear, the jaw crusher thrust board, also called cubits board, in addition to transfer power to and fro dynamic jaw plate do outside, but also has a safety insurance effect, changing its length also can rise to adjust the role of ore mouth platoon.

When jaw crusher crushing cavity things (such as crushing in an iron ball, iron, etc.), for the protection of the equipment is mainly parts are not damaged and use as crusher insurance after thrust board components. With cast iron plate after general thrust moulds overall, in which a trough of some holes open or to lower the cross-section intensity; Also can cast two, then use screws (or rivets) of connecting thrust board, combined. When not broken objects into crushing cavity, equipment overloaded and huge breakage force to thrust plate lead to thrust board broken or combination thrust board screw, machine cut to stop work, have insurance effect.

These knowledge may in equipment instructions say not so detailed, so the user is in the purchase equipment, installation debugging when must learn more with crusher experts, mastering jaw crusher insurance and discharging adjustment, stable production can be better.

Along with the continuous abrasion gear plate, ranking ore mouth bigger product constantly coarsens, in order to obtain qualified product size, need regular adjustment row ore mouth size. Row the adjusting methods of the ore mouth basically has the following two:

1, gasket adjustment, namely the bearing seat behind thrust board with frame behind after a group of gasket placed between wall, increase or decrease gaskets quantity or changing its thickness, can achieve the purpose of adjusting row ore mouth. This compact structure, regulating and reliable, large and medium-sized jaw crusher multi-purpose the regulation method.

2, wedge block regulation, it is to use on thrust board with frame between the backseat two wedge block adjustment is suitable for small crusher adopted

Link to resist the strain as a result, it is manufactured with ast steel, in order to reduce the quality of connecting rod, connecting rod made often of the lower section of the special shapes. Large jaw crushing machine is chiefly used a combination rod. Combination of link quality, tiny, save material, & has a simple device.Thrust plate, also known as brackets, is passed to the jaw movement of a bar, & use it as a device. Alter the length, you can also fine-tune the size of discharge mouth. Usually with the whole forged iron cast whole also cast pieces of, then bolts or rivets joined up.
