Raymond Mill

About Raymond Mill:

Raymond mill is widely used in the field of metallurgy, building materials, chemical industry and mining to process powder. The series is used in grinding the non-flammable and non-explosive stuff which has the Mohs hardness below 7, humidity less than 6%, such as gypsum, talc, calcite, limestone, marble, feldspar, barite, dolomite, granite, kaolin, bentonite, bauxite, iron ore etc., the final products change from 613 micron to 44 micron. Through the function of separator and blower, raymond mill can meet different customers demand.
The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.

Raymond Mill has almost several tens of years history, and the kefid Raymond mill has the same age with the first one all over the world.Currently, the most popular Raymond mill in the leading position are on the basis of Newell Company and occupies 70% market share. Raymond mill’s production and the development has closely related to the development of scrap industry.

Features and benefits:

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.
