Vertical Shaft Impact Crusher

The main way to adjust the reduction ratio of the VSI and GS is by adjusting the rotor rip speed. This can be done by a variable speed drive or by changing the motor/crusher pulleys. At a rotor tip speed of 45m/s, crushing is at its lowest, but we have a high capacity. At 82m/s, crushing is at its highest, but we have a lower capacity.

Impact Crusher Wear Parts Qiming Machinery

Blow bars are the most important wear parts for impact crusher. Wear parts inserted into the rotor which impact the rock to cause breakage. These can be replaced when they are worn down. Rotor. This is the main part of the impact crusher. It holds the blow bars and rotates at a high speed, being driven by a pulley connected directly to the engine.

This invention relates to rotary impact crusher rotors used to communicate rock and to such rotors which are of substantially triangular shape having outlets at the apices of the triangle. This results in a rotor having reduced wearing surfaces and also avoids destruction or explosion of the rotor in the event of an excessive build up of rock in the crusher chamber.

Heavy Hammer Crusher Speed

The rotor consists of a main shaft, a disc, a pin and a hammer. The motor drives the rotor to rotate at high speed in the crushing chamber. The material is fed into the machine from the upper feed port and is crushed by the impact of the high-speed moving hammer. The rotor speed of the heavy hammer crusher can be designed according to the ...
