The Colloidal Mill works on the rotorstator principle. Due to shaving, when the material is pass between the narrow gap of rotor and stator milling surfaces, the size reduction is an effect. A rotor turns rpm at high speeds. The high hydraulic shear levels applied to liquid disrupting structures in the fluid process.

In either, the primary role is to provide an airlock function to minimize the introduction of "false air" into the mill and separator. Excessive false air has negative consequences: The ID fan must be larger; therefore, more costly to acquire and operate.

Rawmix is then fed to a cement kiln, which transforms it into clinker, which is then ground to make cement in the cement raw milling stage of the process effectively defines the chemistry (and therefore physical properties) of the finished ...
WhatsApp: +86 18838072829Our ATOX® Coal Mill is a compact vertical roller mill that can grind almost any type of raw coal. The coal mill utilises compression and shear force generated between the large rollers and the rotating table to crush and grind raw coal, removing the need for a separate piece of equipment for crushing. The coal mill can also grind petroleum ...
WhatsApp: +86 18838072829Mediumspeed mill. Mediumspeed mills are smaller than lowspeed units and are generally of the vertical spindle construction. The speed of the grinding section of these mills is usually 75225 rpm. They operate on the principles of crushing and attrition. Pulverization takes place between two surfaces, one rolling on top of the other.
WhatsApp: +86 18838072829Colloidal mill Working/ mechanism: The liquid containing Solid particles is put into the hopper. A suspension or liquid passes through the moving part (Rotor) and NonMoving (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 ...
