Vibration Mill
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.

Vibration Mill Manufacturer
Vibration mills are similar to ball mills in that particles of the materials are crushed between porcelain or metal balls and the mill body. Drugs and excipients are readily ground to less than 5 μm, the grinding time being considerably less than is required in normal ball milling. As a result, the efficiency of the comminution process in ...

What are the precautions for a vertical mill operation?
Vibration is a common situation in the operation of roller mills. Reasonable vibration is allowed, but if the vibration is too large, it will cause mechanical damage to the grinding disc and grinding roller, as well as damage to ancillary equipment and measuring instruments. The uneven thickness of the material layer is the main cause of vibration.
