The equipment is equipped with a built-in classifier wheel, which not only ensures the production of particle size products free of coarse particles but also avoids the inherent defects of the external grinding-classification circulation system. Moreover, compared with mills using external classification circuits, the internal classification design for coarse materials enables the overall process to be more stable and consume less energy. This type of machine is usually called an ACM.
The inner cavity of the machine body is cylindrical, the upper section is an air classifier and the lower section is an ultra-fine grinding mill. The grinding chamber is composed of a grinding disc and a grinding block, which is used to crush materials into fine powder. The grading chamber is composed of a classifying impeller, which can separate fine powder into two types of particle specifications: qualified and unqualified. The qualified particles are discharged through the discharge pipe and collected by the cyclone collector. Unqualified particles will return to the grinding chamber along the inner wall of the cavity and continue shattered.
The grinding disc and classifying impeller are driven by their respective driving systems, the speed of the classifying impeller is adjustable to meet different size requirements. The spiral feeding system is located on the inner wall of the machine and is used to send materials uniformly into the grinding chamber, the amount can be adjusted by rotational speed.
