What is Vibration Mill Used For?
A vibration mill is a type of grinding mill that uses vibration to mill, grind, or polish materials. Unlike other milling techniques that rely on impact, compression, or shear forces, a vibration mill applies mechanical vibration energy to the material, which causes high-frequency collisions and friction between the particles.
