When the colloid mill is working, it is driven by a motor, which drives the rotating teeth (or called the rotor) and the matching fixed teeth (or called the stator). There is an adjustable gap
between the two grinding bodies. When the material passes through this gap, due to the high-speed rotation of the rotor, the speed of the material attached to the rotor surface increases, while the
speed of the material attached to the stator surface is zero. In this way, a sharp velocity gradient is generated, so that the material is subjected to physical effects such as strong shearing,
friction, high-frequency vibration, high-speed vortex, etc., so that the material is effectively emulsified, dispersed, homogenized and pulverized to achieve the effect of material pulverization and
emulsification. .
