A vertical grinding mill consists of the following components: Electric Motor - to rotate the grinding table. The electric motor is often a three phase variable speed drive (VSD) induction motor, but designs vary. Reduction Gearbox - to reduce the rotational speed of the incoming motor shaft prior to a secondary shaft connecting to the grinding ...
FEECO hammer mills utilize a central rotating shaft, fitted with several "hammers" affixed to pivots on the shaft. As the shaft spins, the hammers are swung via rotational energy, causing them to collide with the material, breaking it up into smaller particles. Hammer mills are flexible, and can be used in a variety of applications.
The hammer mill has 32 pieces of swing hammer of 6.4 × 50.8 × 120 mm on a 610-mm diameter rotor. The tip of the hammers reaches a linear speed of 115 m/s. The air flow rate of the blower is 63 m 3 /min. The total rated power of the hammer mill circuit was 42 kW (Table 1). Several different sized screens were used to investigate their effect ...

Summary. Finished particle size is determined by a combination of screen size, rotor speed, and the size and number of hammers. Material must remain in the grinding chamber until it is able to pass through the screen covering the hammer mill's discharge opening. Optimal screen size is determined by the desired finished particle size, and the ...
