Thrust plate of jaw crusher machine is also known as the bracket; it can transfer power to make dynamic jaw plate swing, at the same time, has insurance effect; changing length of jaw crusher machine can also play the role of adjusting throat.
When unbreakable materials enter into crushing cavity of jaw crushing plant, in order to protect main components from being damaged, we can adopt rear thrust plate as insurance part of the jaw crushing plant. Rear thrust plate is cast into a whole by wrought iron in general; opening a slot or a number of holes in the department can reduce the strength of cross section; rear thrust plate can also be made into two pieces, then connected by screw or rivet to form a combination thrust plate.
When unbreakable materials enter into crushing cavity of jaw crusher machine, the equipment overloads, so huge breakage force pass on thrust plate of aggregate jaw crusher, which leads to the thrust plate breaks or screw of combination thrust plate ruptures; then the jaw crushing plant stops working, playing a role of insurance.
As the constant wear of toothed plate, throat increases gradually, products become coarse constantly; in order to get qualified product particle size, we need to adjust the throat size of jaw crushing plant on a regular basis, with the following two methods:
1, gasket adjustment, that is, equip with a set of gaskets between fulcrum bearing of rear thrust plate and back wall of rack, to achieve the purpose of adjusting throat by increasing or decreasing the number of gasket.
2, wedge block adjustment; the method makes use of two wedge blocks set between fulcrum bearing of rear thrust plate and back wall of rack to adjust the throat; the method is suitable for small aggregate jaw crusher.
Hongxing technical experts remind you mechanical to look carefully operating instructions of aggregate jaw crusher; completely understand the structure principle so that operate and upkeep it appropriately.
