The counterattack impact crusher is also called impact pulverizer or impact breaker. Impact stone crusher has the features of heavy duty rotor design, unique hammer locking system, interchangeable wearing parts, and easy maintenance. The stone impactor provides customers low capital cost solutions, outstanding performance, good cubical shape, lowest operation cost per ton, and wide materials applications.
There is a failure impact crushing machine, after collapse of the seriously damage crusher we found:
1. The rotor is casting, the surface is very rough and the contact surface of each other is for contacts or line contact. The flat head bolts contact the wedge is also have rough surface, have bad contact.
2. The bolt of the incoming lining board bolt are all cut off, the liner fall off, the flat head wedge bolt fault.
3. The flat head bolts for positioning have rough surface, and the gap is too large, can't positioning.
4. The flat head bolts contacted rotor is for M12, but the hole of rotor is for 23 or 25.
After in view of the above analysis, the key to repair the stone impactor is prosition, so we can take the following measures:
1. Processing the convex and concave set in the surface of the rotor in order to have the function of positioning, avoid shift under the action of centrifugal force
2. Milling the rotor surfaces of the impact crusher, improve the surface quality, in order to ensure the good contacts.
3. The contacting bolts we should choose the type of M20, in order to guarantee the conjunction.
Henan Hongxing Mining Machinery Co., Ltd. can according to your needs provide various mobile type crushers: mobile jaw crusher, mobile impact crusher, mobile cone crusher and mobile screening equipment, and we also provide single crushing equipment, which have the best quality in the broken industry, but the most reasonable price.
