The jaw crusher is divided into compound pendulum and Blake, general compound pendulum with safety protection device, the main bracket breaking method, flywheel torque limit protection method and hydraulic protection and so on. Protection is not reliable and accident need to stop processing there are two methods, and the work efficiency is low, and the reaction time of hydraulic protection the system is short, accurate and reliable, without stopping the machine can automatically resume production, so it has obvious advantages. This paper designed a simple and efficient hydraulic protection system.
The overload protection device working principle principle: the fixed jaw is motionless, fixed on the inner wall of the box body equipment. Through the motor pulley, the eccentric wheel is driven to rotate, so as to drive the movable jaw crushing material. Do pendulum motion, the piston rod of the hydraulic cylinder liner and connected, and a spring rod is hinged on the lower jaw, determines the row of ore the size of the mouth and the broken particle size. When the crushing cavity encountered crushing strength exceeds the set value of the material, the hydraulic cylinder piston backward rapidly shrinking, increasing the port of discharge, the high strength material discharged from the discharge port end. When the high strength material by its own weight automatic row after hydraulic control system act quickly to the hydraulic cylinder The right side of the oil supply, so that the piston left to the limit position, resume normal work
