Six summary work principle and troubleshooting methods of hammer mill

Work principle of hammer mill : Ring die pellet mills primarily relies on influence impact to interrupt materials. The fracture process is roughly introduced. Supplies key in into the mill to suffer impact of high-speed rotary hammer to be broken. Broken supplies obtain the kinetic energy from the hammer and rush to flap and article sieve with the frame body at a higher pace. In the same time, after a number of hitting, supplies that are smaller sized than gap among the sieve content articles will be discharged through the gaps. Meanwhile, bigger supplies will be crushed, grinded, extruded and broken through the hammer around the sieve articles for an additional time. Once the supplies are squeezed from the gaps by hammer, items of required grain dimension arrive out.   Fault and avoidance of hammer mill : 1. Overheating bearing Reason: the grease is insufficient or it can be too much; grease is filthy so as to become metamorphic; displaying is broken.   Elimination method: fill proper grease; grease inside bearing will likely be 50% of the space volume; clean the bearing; replace the grease; replace with a brand new bearing.   2. The size of grain is way too big Reason: hammer is worn seriously; sieve write-up is fractured.   Elimination method: replace the hammer; change sieve write-up.   3. Yield reduction Reason: grinding mill the space of sieve article is blocked; supplies go in an uneven way.   Elimination method: halt it to clean up the stuffing within the gap of sieve articles; adjust the charging institutions.   4. Elastic joints produce knock Reason: pin shaft is loose; elastic ring is worn;   Elimination method: screw along the nut associated with pin shaft; replace the elastic ring.   5. Machine generates knock internally Reason: non-broken materials enter in to the machine; liner fasteners loosing; hammer hits on line board; hammer and other parts are fractured.   Elimination method: halt it to completely clean up the crushing cavity; examine the tighten situation of lining board as well as the gap among hammer and sieve content articles; replace fractured parts.   6. Machine shake Reason: hammer replacement or worn cone make that static balance of rotor don't accord with requirements; hammer is damaged to rotor imbalance; pin shaft turn out to be bent and broken; the triangle plate or round plate crack; the anchor bolts are loose.   Elimination strategy for pellet mill : remove hammer or choose hammer in line with weight. Have the total weight associated with hammer shaft upward adequate to that of the relative hammer shaft upward. That is definitely, static balance must accord with requirements; replace hammer; replace pin shaft; welding repair or replacement; tighten the anchor bolts.
