Impact crusher crushes stone or rock with impact force. When the stone or rock materials enter the blow bar area, they are crushed due to the high-speed impact of the blow bar and are thrown to the impact plates on the rotor for secondary crush. Then the crushed stone and rock materials will be shot back to the blow bar again for the third crushing process. This process repeats until the materials are crushed to the required size and discharged from the lower part of the impact crusher machine. The size and shape of the finished powder can be changed by adjusting the gap between the impact rack and rotor support. The machine employs self-weigh securty device in impact crusher's back frame. When other objects enter the impact cavity, they will be forced out of the machine by the impact rack in the front and back of the impact crusher equipment. CONTINUOUS LUBRICATION impact crusher design All models of the crushers are supplied with high capacity external mounted lubrication unit, composed of oil-tank, oil filtering system, high oil temperature shut-down, low oil flow shut-downs and oil flow gauge, which is designed to supply continuous and stable oil, by forced lubrication to the Cone Crusher, for smooth rotation and operation. SAFETY Jaw Crusher Operation are configured with several safety features. The lubricating unit is interlocked with the main motor, in order to provide additional safety, which includes oil filtration and automatic shut-down in the event of high oil temperature, as well as low oil flow. Crushers are configured with Spring-Loaded release system, which allows any uncrushable material to pass through the crusher, without causing damage to the crusher. The locking system (manual or hydraulic), will easily secure the crushing clearance. All models are configured with proven spring-type mechanism, in order to recover Tramp-Iron and provide protection to the unit.
