Master the Useful Information of Hammer Crusher

Hammer mill crusher is developed for both dry and wet crushing of brittle, medium-hard materials for the mining, cement, coal, metallurgic material, construction material, roadbuilding, and petroleum & chemical industries. The hammer crusher machine crushes by the collisions between high-speed hammer and material, and the hammering machine has the features of simple structure, high reduction ratio, high efficiency, etc.

The Common Problems Causes and Solutions:

1. grinder strong shock:

Cause: The hammer is installed correctly aligned; worn hammer without timely replacement or replacement part hammer, resulting in two groups corresponding to the hammer weight difference is too large; individual hammer stuck, did not throw off; rotor imbalance in other parts of the weight; shaft bending curved; bearing severe wear or damage; bolt loose; hammer line speed is too large.

Solution: Reinstall the original order by; optional hammer to balance the weight of not more than 5 grams; stop feeding, checking off, turned by hand hammer to rotate flexible; balance other parts; straightening or replacing the spindle; timely replacement of bearings, and pay attention to enhance the lubrication; tighten the corner screws; reduce the rotor speed.

2. discharge rate decreased significantly:

Reason: hammer badly worn; mill overloading caused the belt to slip rotor speed is too low; materials too wet sieve cause blockage; hammer gap is too large ( for circulation movement close to the screen surface layer of material movement, by the hammer blow opportunity to reduce the speed is too slow, hampered by inner sieve material ); feeding uneven; supporting underpowered.

Solution: Unified hammer be adjusted for angle or replacement; reduce the load, adjust the belt tension; drying or drying materials; appropriate to reduce the hammer screen space; uniform feeding; choose the right power motor.

3. bearing overheating:

Reason: Bearing damage; little oil; belt too tight; feeding excessive rotation of the rotor resistance increases, long-term overload of work.

Solution: Replace the bearings; filling oil; adjust the belt tension ( tightness in the middle of the hand press hard drive belts, high arc formed 18-25 mm is appropriate ), by changing the relative position of the motor and mill to adjust the tightness of the belt; reduce the amount of feed.

4. finished too rough:

Reason: sieve badly worn or damaged; mesh sieve care and engagement is not close.

Solution: If the damaged area is small sieve, then fill with riveting or soldering method of repair; If a larger area is damaged, it should be replaced sieve.
