Hammer mills also generate heat, especially at when run at high speeds, which may be undesirable for certain applications. With regards to particle size, there is great variability when using a hammer mill. This is because …before it can exit the mill. 2. Rotor Speed. The faster the rotor speed, the more severe and greater the number of times the hammers will impact the material, producing a finer finished particle size. Conversely, a slower rotor speed equates to fewer hammer impacts, and a coarser end product with fewer fines generated. 3. Hammer size and number.
