Circulating mixing grinder is a version integrating stirring grinder an stiffing type mixing cylinder. It is normally used for grinding materials with granularity up to micrometer class, which have high-quality requirements and are difficult to be ground and distributed. The machine can have material ground within a very narrow range of granularity. Abrssive medium and grinding chamber expending less money can process a great deal of materials. Liquor mateials can be monitored continuously and other additives be added into mixing cylinder at all time during grinding. For those sensitive compositions, they can be added before the end of grinding, because liquor mterial stays a very short time in grinding chamber, but most of grinding time in mixing cylinder. In this way temperature of liquor material can be effectively controllde.
