Installation of hammer mill

  • GEMCO hammer mill can be divided into powder storage pool, storage bag and storage bin. Each type must be well ventilated, have adequate evacuation rooms and reliable fire fighting equipment.
  • If the motor is prepared by customers, the belt pulley diameter of motor or diesel engine should be calculated. The specific calculation method is: diameter of engine (electric motor, diesel engine or gasoline engine)=rated revolution speed × belt diameter of hammer mill ÷ rated revolution speed of engine (electric motor, diesel engine or gasoline engine).
  • The speed of diesel engine and gasoline engine is 80% of the rated speed.
  • The hammer mill should be adjusted to the horizontal direction, the anchor bolt should be fastened.

Adjustment and maintenance of hammer mill

  • The sealing situation can be adjusted by adjusting the direction of engine (electric, diesel or fuel engine). The right tightness is archived with the hand can be pressed down around 10cm.
  • Start hammer when hearing abnormal noise, then idle the hammer mill for thirty minutes, when the temperature of main shaft is under or around 25℃, then the hammer can be put into use again.
  • The bearings bear all the load of the machine, good lubrication has a great influence on bearing life, it directly affects the service life of the machine and operation rate, thus grease is required for all bearing parts.
  • Disassembly and assembly of screen: put the side with burr upward to avoid screen clogging.
  • After a period of use, tip of hammer gradually wears. When the first tip is worn, turn the hammer to use the second, third and fourth tip. In order to ensure the balance of the rotor and avoid vibration, all blades must be turned at the same time. change the tips immediately when the third tip is worn.

Operation principle of GEMCO biomass hammer mill

After sent into the grinding chamber, the raw material will be crushed by hammer with high rotating speed. Under the action of centrifugal force, the crushed material will be continuously squeezed, bumped, hammered, rubbed by hammer, crusher plate, and screen mesh. Through the sieve, crushed particle will be sent out of the machine under the action of centrifugal pressure and suction force of the rotor. Particle don’t through the sieve is repeated this process until the screen was sent to the machine.

Notice for hammer mill operation

  • Before running, adjust the hammer mill according to the operation and maintenance guidance, ensure that each fastener is tightened.
  • Disabled individual under 16 years old of over 60 years old, and individual who doesn’t familiar with the performance of hammer mill can’t operate the machine without authorization.
  • Drunk, sick or overworked operator is forbidden to operate the machine.
  • If there are abnormal noise during operation, stop the machine immediately. Cut the power, inspect and clean the hammer mill.
  • It is forbidden to feed the hammer mill from bag directly during operation, in order to ensure the safety of operators.
  • Direction the safety mark points to should be the rotor running direction.
