Raymond Mill

Raymond mill adopts mill disc revolution, mill draft rotation, spring adjustment rod structure, which is able to strengthen press, cutting ability, so as to enhance ability of the mill. It has advantages of high production, fine powder, continuous drying powder, grains are concentratedly scattered, fineness is continuous and adjustable, compact structure, low energy consumption, high efficiency, less power consumption, small working area, less investment each time, easy installation and maintenance, reliable operation and so on. It is suitable for dry and super fine powder processing of ore materials and is an optiumu equipment of mill industry, especially for small sized enterprises.

Raymond mill is widely used in metallurgy, construction materials, chemicals, ores to produce powder, which is suitable for non-flammable and non-exlosive ores with mohs hardness below 9.3, humidity below 6%, such as Gypsum, talc, calcite, limestone, marble and feldspar, barite, dolomite, granite, kaolin, bentonite, stone, bauxite, iron oxide red, iron ore and so on. Fineness of product ranges from 0.613mm to 0.44mm. With joint effects of analyser and fan, different requirements of customers can be fulfilled.

Features and benefits of Raymond mill

1. most raymond mills are used for handling with some frivolous material, but with the deepening of understanding and the superiority of the crushing steel, all kinds of raymond grinding mills are developed quickly and used wider and wider. Even to the entire scrapped cars and household appliances, processed with appropriate conveyor and sorting equipment, the composition of scrap broken lines can be easily finished ,so it is no need to dismantle of scrapped cars and household appliances and it is easily to product and process automatically to get pure crushed steel, non-ferrous metals and non-metallic materials available.
2.The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.
3.Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.
4.Compared with other milling plants, its passing ratio achieves 99%, this is what other mill can not reach.
5.The whole plant is a vertical structure of strong systematic characteristic, so it occupies small area. From crushing of raw material to grinding and packing is an independent production system.
6.Main parts of the whole plant are made from cast and steel of high quality. The technics is so subtly that insures the durability of whole plant.

Raymond Mill Working principle

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.

Application of Raymond Mill

Raymond Mill produced by our company 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 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.
