Stone powder grinding mill machine can be used in more than 150 kinds of different types of stone materials 300-2500 mesh powder making, such as: calcium carbonate, calcite, gypsum, dolomite, feldsapr, carbon black and so on.
The main bearing and each dial are driven by electromotor of main equipment through reducer, and numbers of rings 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 middle of first dial evenly; the materials will be driven to the edge of dial by centrifugal force, and fall into the ring channels and are pressed, crushed 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 Separator. The rotating turbo in the powder Separator 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.
Stone Powder Grinding Mill Machine Features
1. High-efficiency and low consumption
With the same end-products fineness and motor power, its output is over 1 time of that of Jet Mill, Mix Mill, and Ball Mill.
2. Easy-damaged parts with longer working life
The grinding roll and ring are made of special materials. Generally, their work life is more than one year, but, which could come up to over 3 years, when it processes calcium carbonate and Calcite.
3. Security and Reliablity
Because there are no rolling bearing and bolts in the grinding chamber, we can not see the problems of bearings and sealings easily damaged and machine destroyed due to the bolts looseness.
4. Cleansing and Environment Protection
Adoption of Pulse dust collector and muffler reduces the industrial dust pollution and noise, which reaches the National Standard.
