Raymond mill machine

1. Brief introduction of Raymond Mill:Raymond mill produced by our company is mainly used to grind non-inflammable and non-explosive materials with hardness below 7 and moisture content below 6% such as barite, calcite, potash feldspar, talcum, marble, limestone, ceramic, glass, etc Raymond grinder can be used in mining, chemical industry, construction materials, metallurgy and so on.The final products can be adjusted freely from 100 mesh to 425 mesh.

2. Characteristics of Raymond Mill:

·Its using structure needs only small square meters to install and makes the whole set more compact and integrated, starting from raw material to crushing, to grinding, to powder-output and packaging all in one system.

·The equipment stands out in ensuring the evenness and fineness of powder-products with 99% pass-through mesh rate at any fineness-level you adjusted. In this respect, the equipment finds no competitor.

·The grinder’s transmission system consisting of well-sealed  gear-case ensure smooth-transmission and efficient operation.

·The key components of the grinder are made of high-quality steel and therefore the grinder runs with stable and reliable functions.

·The central-control is adopted for its electrical system with the best-selected device.

·In the department of grinding automatic operation can be realized.

·The vibrating feeder is small in size, light in weight, and feeds evenly, which reduces the cost of energy and is easy to use, maintain and repair.

3. Advantages of Raymond Mill:

·Comparing with other grinder, under alike of the power condition, the output can increase 20-30%,the Roller’s pressure on account of the action of the high barometric maxima spring can increase 800-1200kg.

·Mineral that  hardness is smaller 9.3 stages can process, crush.

·Completed product that particle sphere that diameter maximum is very extensive, particle is 0.613mm (30 mesh), the normal particle is 0.033mm and the smallest particle is 0.013mm.(1000mesh).

·The effect of the elimination dust attain the national standard.

·The accommodation of the analyzer is very convenient.

·Grinding apparatus adopt lap multistage seal, and the seal is effective.

4. Working Principle of Raymond Mill:

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.
