Raymond Mill Overview

Raymond mill is a kind of new-typed moderating-speed coal mill, which is developed on the basis of RP. Rraymond mill designed by SBM adopts German advanced-milling technology, combining the characteristics of similar domestic products. The structure of it is getting perfect by low consumption, low investment, environment friendly, small occupation area, and more efficient than the traditional mill, after many years of practice and improvement.

Raymond Mill parts

The Raymond mill consists of motor, reducer, case, milling device, separator, outlet, coal feeding pipe, loading device, control box and sealing apparatus. SBM is raymond mill manufacturer in China, sale raymond mill to many countries such as USA, Indonesia, Vietnam, India, Europe, Africa. The fittings are all of superior performance in the world at present. We ensure good quality and durability of the whole raymond mill machine.

Raymond Mill Application

Raymond mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mine ore mining etc. It can produce powder from more than 280 kinds of non-flammable and non-explosive mineral materials with Mohs hardness below 7 and humidity below 6%, such as barite, limestone, quartz, calcite, granite, porcelain clay, basalt, gypsum, coal, kaolin, talc, mica, feldspar,calcium carbonate etc. The final size of raymond mill is between 0.613mm—0.044mm(100 mesh to 325 mesh). So raymond mill is the optimal milling equipment in electric power, metallurgy and cement industries.

Raymond Mill Main Features and Benefits

1. The whole raymond mill 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.
2. Compared with other milling plants, passing ratio of Raymond mill achieves 99%, which other mill can not reach.
3. Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.
4. The electric control system is centralized controlled, so the automaticity is high, no people are needed in the operating room.
5. Main parts of the whole raymond mill plant are made from cast and steel of high quality. Such strict techniques insure the durability of whole plant.

Raymond Mill working principle

The working principle of Raymond Mill is as follows:
Firstly, raw material is crushed by jaw crusher to the size raymond mill required, then the crushed materials are 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 ring and roller to accomplish the grind.
After this, the ground stuffs are carried by the air from the blower into the separator for screening. The fine powers are blow into the cyclone collector and are poured out through the output-powder valve as the final products and the rough stuff after the screening will be recycled back into the grinding chamber for regrinding. The set’s airflow system is closely sealed up and circulated under condition of negative and positive pressure.

Raymond mill maintenance

Raymond mill havs many notices about operation and maintenance. Raymond Mill special maintenance and routine maintenance guidelines are as follows:
1. There must be someone that shall be specifically responsible for operation and maintenance of control cabinet of raymond mill.
2. regular check the cabinet, maintain meter display clear and bright, keep operating handle movement keep contactors and the Master electric shock without the dust.
3. regular check whether all components and connectors of raymond mill are loose or damaged.
4. every six months telemetry insulation resistance. Once discover problems, timely deal with them.
