Grinder machine brief introduction:
Grinder machine is a new kind of powder grinder mill, which is invented with great concentration and on the basis of many years of powder processing experiences. This invention starts an epoch of high efficiency and low cost in international mining industry. High Pressure Suspension 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). High Pressure Suspension 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.
Grinder machine Application:
The grinder machine can grind the following non-inflammable and non-explosive materials with the hardness below Scale 9.3 of Moh's and the moisture content below 6%,such as:
a) Minerals:limestone, calcite, barite, dolomite, potassium feldspar, marble, talcum, gypsum, kaoline, medical stone, rock phosphate,etc.
b) Metallurgy materials: manganese ore, iron ore.etc.
c) Chemical materials: active carbon, carbon black,etc.
d) Building materials:glass, ceram, fireproof materials, heat preservation materials,etc.
Grinder machine Working Principle:
Firstly, raw material is crushed by jaw crusher to the size required, then elevated into a hopper from which the material is transported through the electro-magnetic vibrating feeder evenly and continuously into the grinding chamber for powder-processing. The rollers oscillate outward to press the ring because of the centrifugal force and the shovel scoops up the materials, send to the middle between the ring and rollers to accomplish the grinding.After grinding, the rough materials will be recycled by the air from the fan back into the grinding chamber for regrinding and the fine powders are blew into the cyclone and poured out through the output-powder pipe as the final products.
