Trouble Shooting of Crusher
Crusher machine is the main crushing equipment in stone crushing production line. During its working process, the improper operation or untimely maintenance may cause the crusher failure, so as to influence the production efficiency of the whole production line. When the fault appears, we should fine the problem and take trouble shooting at the first time. Here, the editor will list six faults of crusher and its solution.
A. Bigger crusher vibration
1. Rotor imbalance. Make the static balance of rotor.
2. Join bolts of cover, body, batholith etc. are loose. Screw down the join bolts of cover, body, batholith etc.
3. Bear is damaged. Replace the bearing with new one.
B. There is deviant striking and large vibration in crusher
1. Iron or uncrushed materials enter in the crusher. Stop the machine and take out the iron or unbreakable material.
2. Scale board is not close to body. Tighten the liner bolts.
3. Small clearance causes the collision between hammerhead and scaleboard. Grind off excrescent part between hammerhead and scale board, making suitable clearance.
C. Bearing temperature is too high
1. Poor lubrication, bad wear from lacking oil, grease failure. Clean oil route, bearing, fill or replace the oil. Choose proper grease.
2. Bearing damage. Replacing bearing with the new one.
D. Spindle speed slowed down, the motor current increase, low output
1. Materials are more moisture. Control the water content of materials to 50%.
2. V belt looses. Adjust V belt to proper tension.
3. Uneven feeding or materials jam. Control feeding and feed evenly.
E. Bigger discharge size
1. There is larger clearance between hammerhead and impact plate. Timely regulate the clearance between hammerhead and impact plate.
2. The hammerhead and impact plate are seriously worn. Replace hammerhead and impact plate with a new one.
F. The temperature of motor bearing rises
1. Greasing failure to bearing. Clean bearing, fill or replace lubricant.
2. Bearing damage. Replace the bearing with a new one.
3. Belt tension is too sufficient. Set the belt to a proper level.
