The Vibration Mill uses a vibrator attached to a drum (grinding cylinder). The drum is partially filled with a grinding media and material to be ground and is subjected to vibrations which stir the grinding media. The grinding force of the vibration mill is 6 to 10G compared with that of the conventional rotating ball mills, 1G.
The characteristics of the rod mill are that the product is relatively rough. Still, the particle size is uniform, containing less coarse sand and sludge, and the over-grinding is lighter. The discharge particle size is usually between 0.833~0.147mm, and the particle size characteristics of the rod mill product differ from those of the rod mill.
