A colloidal mill is used to break down a mixture that contains Suspended solid particles to make a homogeneous mixture. The liquid containing Solid particles is put into the hopper. A suspension or liquid passes through the moving part (Rotor) and Non-Moving (Stator), which causes a high shearing force between the two narrow gaps. Shear stress force can be reduced or increased by changing the gap (50 to 1000 mm) and by changing rotor speed (1000 to 25000 rpm), but in most cases, the speed is (2000 to 18000 rpm). The liquid mixture continuously flows through these two-part and makes it homogeneous, then finally drains out through the outlet.
