Product Description

The Dingbo three-ring micro powder mill(ultrafine mill) ID for super-fine grinding materials with hardness less than 6 in Moh's scale and humidity less than 6 percent such as kaolin, limestone, calcite, marble, talcum, barite, gypsum, dolomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment and so on. The granularity of the end products is 325-2500 meshes(0.044-0.0055mm).

Working principle
The main bearing and each dial are driven by electromotor of main equipment through reducer, and numbers of ring and rolls which are rolling in the ring channels are driven by dial through plunger. After being crushed by hammer crusher, the big materials become small ones and they are sent to the storage bin by elevator. The electromagnetic vibrating feeder sends them to the edge of dial by centrifugal force, and ground by the grinding rings and rolls. Then the materials fall into the second and third ring and crushed and ground. The high pressure centrifugal blower inhales air from the outside and blow the materials which are ground in the third ring to powder Seperator. The rotating turbo in the powder Seperator makes the coarse materials return to the mill and reground, while the fineness mixes with the air and be drawn to the cyclone and be discharged from the discharging valve which is in the bottom of it. The air which mixed with very little fineness are purified by impulse dust catcher and discharged by blower and muffler.
