Colloid mill is a common material crushing process. It mainly achieves the purpose of crushing and mixing through the relative movement between a high-speed rotating rotor and a fixed stator.
The key components of the colloid mill are the rotor and the stator. The rotor is driven by a high-speed motor and rotates through the power of the motor. The stator is relatively fixed to the rotor and fixed on the frame of the machine.
When the motor starts, the rotor begins to rotate at high speed. The material is injected into the colloid mill through the feed port and falls into the grinding groove between the rotor and the stator. Under the rotation of the rotor, the material is sheared, vibrated and impacted.
The surface of the rotor is usually equipped with special grinding teeth or grinding discs, which produce high-speed relative motion, subjecting the material to shearing and impact forces. At the same time, due to the inconsistent width of the slot between the rotor and the stator, a dynamic and static pressure difference is formed, causing shearing and extrusion of the material.
In this process, the material is continuously sheared and squeezed, and the particles are refined. This is because the high-speed rotation of the rotor and the unique groove design cause the material to be exposed to a variety of contact methods in the grinding groove, and in different ways Different forces are generated under different contact modes.
Finally, the material is crushed into fine particles in a colloid mill and thoroughly mixed with other ingredients. By increasing the rotation speed of the rotor and adjusting the flow speed of the material, the degree of crushing and mixing uniformity of the material can be controlled.
