Model 4R3216

• Mining and Oil Refining Machinery & Accessories

The Raymond Grinder, Model 4R3216 is mainly used to grind non-inflammable and non-explosive materials with Moh’s hardness below 7 and moisture content below 6% such as barite, calcite, potash feldspar, talcum, marble, limestone, ceramic, glass, etc. The final products can be adjusted freely from 100 to 425 meshes. Working principle: the 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.

It is used in mining, chemical industry, construction materials, metallurgy and so on.

Three-dimensional structure, land saving, easy to be a whole set; screen passing rate can reach to 99%; the transmission is steady and reliable; and centralised control for the electric system and convenient to operate.

Roller number: 4; maximum feed size (mm): 25; fineness of product (mm): 0.2-0.044; capacity (t/h): 1.8-4.5; weight (t): 15 and main frame powder (kW): 37.
