Working principle
Circulating mixing ball mill is a type of machine that combines a mixing ball mill with a large capacity premix cylinder, using a pump to circulate at high speed to achieve fast grinding effect and narrow particle size distribution. The rapid circulation of materials through intense agitation of the grinding medium layer is conducive to obtaining a narrower particle size distribution, allowing smaller particles to pass through quickly, while relatively coarse particles need to stay for a longer time and have a priority crushing effect on coarse particles. Circulating agitator mills are commonly used for grinding materials that require a size of micrometers, high quality requirements, and are difficult to grind and disperse.

The main feature of a circulating stirring ball mill is that it can obtain a narrow particle size distribution after grinding, with less investment in grinding medium and grinding chamber, but can handle a large amount of materials. The slurry can be continuously monitored, and other formula components can be added to the pre mixing tank at any time during the grinding process. More sensitive components can be added near the end of the grinding process. Due to the short residence time of the slurry in the grinding chamber, most of the time is spent in the pre mixing cylinder, which makes it have good temperature control.

Cylinder liner: Ceramic (alumina), ceramic tiles, food grade rubber, or polyurethane can be selected as the liner.
Stirring arm sleeve: optional polyurethane, tungsten carbide, zirconia, etc.
Cylinder head: can be equipped with a floating shaft seal to reduce solvent loss or for inert gas protection.
