Applied Field: Sand making impact crusher is suitable for the crushing and shaping of soft, medium-hard, and extremely hard materials. It is widely used in various industries such as ores, cement, refractory materials, bauxite clinker, carborundum, glass raw material, machine-made building sand, stone and various metallurgical slag etc. Sand making impact crusher is the first choice of machine-made sand equipment in machine-made sand production, building and road construction with high crushing capacity.
Working Principle of Sand Making Impact Crusher
Sand making impact crusher adopts the principle of "stone striking stone". The stone in the natural falling process collides with the stones are thrown out by accelerated impeller, so as to achieve the purpose of crushing. Then the stones thrown out by acceleration collide with the naturally falling stone with forming of a vortex and crush again during the return process, so the abrasion of the impact plate of the sand making impact crusher is very little during the operation.
Common Faults and Troubleshooting Methods of Sand Making Impact Crusher
1.The body of sand making impact crusher swings too much. Troubleshooting: the wear parts on the impeller are seriously worn, so replace the wearing parts. The feed particle is too large and reduces the feed size. If there is a blockage in the impeller passage, take out the blockage.
2.The particle size of the finished product is too large. Troubleshooting: the V-belt is too loose, so tighten the V-belt.
3.Excessive idling resistance. Troubleshooting: the sealing cover of sand making impact crusher on the bearing is filled with material, so open the upper seal cover to remove.
4.Bearing heating. Troubleshooting: lack of oil or dust, refuel or clean the sand making impact crusher. If the bearing is damaged, replace the bearing.
5. Metal collision. Troubleshooting: liner or impeller vulnerable parts of sand making impact crusher fall off, so just re-tighten.
