Imapct Crusher Overview

Imapct crushers are suitable for materials whose compressive strength is under 360Mpa, and particle size is under 500mm. This kind of machine features easy maintenance, high crushing ratio and crushing efficiency etc. With end products in cubic shape, impact crushers are the ideal crusher for aggregates processing in high-type highway building, water conservancy and power construction.

Imapct Crusher Application

Impact crusher is suitable for materials whose compressive strength is under 360Mpa and side length is under 500mm. Impact crusher are preferred to crush granite, limestone, rivel gravel, etc.

Imapct Crusher Working Principle

Impact crushers use impact energy to crush materials. Driven by the motor, the rotor revolves at a high speed. Revolving blow bars in the rotor blow the materials. Then the materials will be thrown to the impact plates for secondary crushing. The materials will be shot back to the blow bars again. This process repeats until the materials are crushed to the required size and discharged through the discharging opening at the bottom of the machine. Adjusting the gap between the impact rack and rotor support, the size and shape of the end products can be changed.

Impact Crusher Work Notice

In the work process, pay special attention to what happen as follows:
A.the bearing temperature is too high
Solution:
   1. First, check whether the grease is reducing;
   2. Standard terms of bearing grease should be filled with volume 50%;
   3. timely clean bearings, replace grease;
   4. If badly worn, replace the bearings.
B.In operation process, crushing chamber internally generated percussion sound very keen.
solution:
   1. immediately turn off the power, and clean up the crushing chamber to check whether there are the material that can not be broken.
   2. Check the lining of the fastening conditions and the gap between the hammer and the liner; whether the wear-resistant lining is shed.
   3. Replace the broken machine
C.The final size of impact crusher is too large.
solution:
   1. adjuste the gap between before and after the frame, or replace the worn grave liner and board hammer;
   2. adjust position of the counter-attack planes
