· Crusher crusher introduced is a new high-efficiency crushing equipment, which is characterized by small size, simple structure, large crushing ratio (up to 40), low energy consumption, large capacity, uniform particle size and selective crushing effect, is promising device. At present, because some wear-resistant materials, and in some metal concentrator has been applied. PF-I type crusher series impact crusher can process the side length of 100 to 500 mm below the material, its compressive strength up to 350 MPa, with a crushing ratio, after the material was broken advantage cubic particles. · Crusher works by stone crusher machine directly into the upper part of the high-speed rotating turntable; the role of the high-speed centrifugal force, and another part of the way to bypass the turntable umbrella flying around the stone to produce high-speed collision with high density of crushed stone in the fight against one another, between the wheel and the chassis will form a vortex motion caused by repeatedly hit each other, friction, grinding, through discharge from the bottom. Forming a closed loop several times to reach the required screening equipment is controlled by the size · Crusher (Crusher) Installation and commissioning installation: Press the scope of this machine select the installation location, while ensuring that there is sufficient space for maintenance. Debugging: 1. rotor at the factory through balanced, users generally do not need to strike a balance test, when replacing the hammer and rotor parts, should be balanced configuration. 2. The host installation should be adjusted to balance the spindle level error is less than 1mm / m, the main driven wheels in the same plane, adjust the belt tension moderate, fixed motors. 3. Check whether the installation location of the components move, deformation, lock all the bolts, check the seal is good. 4. Check the electrical box and fasten the wiring, adjust the time delay relay and overload protection, connected to the circuit, the test motor rotation, select the appropriate size of the fuse. 5. Check whether the reliable operation of the hydraulic system, with or without leakage. 6. clear the crusher foreign body, hands moving rotor, check friction, collision.
