Colloidal grinding is made of stainless steel or plate stainless steel and is commonly used in industries such as food and chemical industry. Its principle is to rotate the fixed and rotating teeth at high speed, and the processed material generates downward spiral impact force through its own weight or external pressure (which can be generated by the pump). When passing through the gap between the fixed and rotating teeth (adjustable gap), it is subjected to strong physical effects such as shear force, friction force, and high-frequency vibration, Effectively emulsify, disperse, and crush materials.
