Overview of Grinding Mill:

Stone grinding mill is a new kind of mill, which is invented with great concentration and on the basis of many years of powder processing experiences. This invention started with an epoch of high efficiency and low cost in international mining industry. Stone grinding mill can be used to grind non-inflammable and non-explosive materials with Moh's hardness below 9.3 and moisture content below 6%, such as barite, limestone, pottery, scoria. Size of final products can be adjusted between 80-425 mesh (The fineness can reach 1000 mesh).Stone grinding mill can produce coarse powder between 30-80 mesh by adding special equipment. This machine is widely used in the fields like mining, chemical industry, construction materials, metallurgy, etc.


Working Principle of Stone Grinding Mill:

In the mainframe of Stone grinding mill, there are strong springs with pressure as high as 1000-1500 kg equipped on the roller suspender. Stone grinding mill works, the roller rotates around the principal axis, and clings to ring under the effect of the strong spring and eccentricity. Its press is 1.2 times of Raymond mill under the same press condition, so the production is largely increased. When the materials are sent into the grinding chamber, they are brought to the space between the roller and ring and get grinded. Then the powder grinder will be blown into separator. The fine powder after departed with the air is discharged through the outlet as final product. The large-sized powder falls back for regrinding. The air will be back to the blower for repetition of the above process. The left air wil come to the bag filter to get cleaned. When the wear and tear between roller and the ring reaches certain degree, it adjusts the length of the strong spring, , so to keep the invariable pressure between the roller and the ring, to make sure the stable production and the fineness.
