Vibration Mill Used for fine grinding of soft and hard materials under vibrating action. Under the high-frequency vibration of an exciter or vibration motor, the grinding media (pins, cylpebs or balls) in the cylinder performs strong projectile, high-speed rotation and slow revolution. This causes powerful impacts, friction and shearing action ...
Grinding mills are infamous for their extremely low energy efficiency. It is generally accepted that the energy required to produce new mineral surfaces is less than 1% of the electricity consumed ...
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 motion of the jar follows a …
Material with high stickiness creates problems in all aspects of the grinding process, including feeding (e.g., making metering into the mill difficult), grinding (e. g., plugging the hammer mill screen or blocking the air classifier of a jet mill), and collection (e.g., plugging the bag filters). There are two ways to grind sticky materials.
Energy consumed during grinding process will raise the grinding zone temperature. Therefore, all influential factors on grinding force will in turn affect the thermal performance of grinding. The grinding zone temperature elevation is dependent on the grinding efficiency and the proportion of grinding energy that enters the workpiece.
