Crusher machine accordance with the categories can be divided into medical crusher and mining crusher. Medical stone crusher is mainly used for crushing, generally use the resonance stones broken to avoid surgical risk; mining crusher mainly various types of stone crushing operations, according to the principles of the broken and product particles of different sizes, is divided into many models.
When the solution to the crusher blocking mine:
Pai mine mouth adjust the insurance principle can be summarized as follows: when decreasing the port of discharge, the hydraulic oil from the tank after the hydraulic pump and valve pressed into the bottom of the hydraulic cylinder, hydraulic cylinder piston top starter cone, so that the discharge mouth reduced. When increasing the port of discharge, the part of the high-pressure oil hydraulic cylinder piston below, through the external thread cut-off valve and manual valve back into the fuel tank, moving cone landed, Pai mine mouth increases.
When iron, due to the moving cone downward vertical force increases, so that the hydraulic cylinder piston below the oil pressure is greater than 5MPa oil into the accumulator, the nitrogen compression piston and movable cone with decline, increasing discharge mouth large. Iron is excreted in nitrogen under pressure, moving cone in situ recovery crusher continue to work to complete over iron Insurance.
Impact Crusher occurred plugging Mine phenomenon, can make moving cone rise, decline, and so forth several times, will be able to discharge blocking mine. Is equal to the horizontal cross section of the crusher tank and the hydraulic cylinder, Dayou from the tank to the hydraulic cylinder in the hydraulic system, the decline in the oil surface of the tank is equal to the rise in the oil surface of the hydraulic cylinder, and vice versa.
