How does hammer mill work?

Material after conveying into the crushing chamber will be pulverized by the swiftly rotating hammer plates. Then the smashed pieces will be tossed out of the machine by centrifugal force from the rotor and suction force from the fan. Pellets failing to pass through the sieve meshes will be re-pulverized as the same way above.

How to operate a hammer mill?

  • Before stearting the hammer mill, adjust and maintain the hammer mill machine according to the following manual regulations. At the same time check the tightness of fastening parts and make sure each part is lubricated sufficiently. After securing the safety of hammer mill machine and operator, the machine can be started. Idle the hammer machine for 2-3 minutes on hearing no abnormal sounds, and then feed the raw material. Make sure that the working condition is normal before feeding.
  • Feed the material in in a slow and steady way. Overload feeding is forbidden. Feeding rate can be controlled by adjusting the plate. During material blocking at the entrance keep hands away from the feeding port. Hard wood stick force feeding is forbidden.
  • Full storage bag, pool or bin should be discharged in time to avoid air reverse affecting normal working.
  • Fit the sieve mesh with the machine lower body tight to avoid material leakage to affect the crushing quality.
  • Stop and then inspect the machine if there is any abnormal noise during operation. It is forbidden to inspect hammer machine on running.
  • Keep frequent inspection on hammer blades worn degree and cotter pin condition, and replace the worn parts in time on cutting off the power source. Opening the upper body during running is forbidden.
  • After inspection, close the upper body and make sure the upper body be aligned with lower body. Tighten the fixed hand wheel and move the main shaft to make sure the main shaft move flexibly with no bumping, scratching or clashing sound inside the machine.
  • After each shift, idle the machine for 5-10 minutes to suck the material clean and stop the machine. Add lubricating grease to main shaft bearings.
