Raymond Mill Overview

After many years of practice and improvement by manufacturer Shanghai Shibang Machinery Company, the structure of raymond mill is getting perfect by low consumption, low investment, environment friendly, small occupation area, and more efficient than the traditional industrial grinding mill.

Raymond Mill Application

Raymond mill is mainly applied to the powder processing of mineral products in industries of metallurgy, construction, chemistry, and mining etc. Raymond mill 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 etc. The final size is between 613micron and 440 micron(0.613mmí¬0.044mm).

Raymond Mill Features and Benefits

1. The whole plant of raymond mill 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 or traditional raymond mill, its passing ratio achieves 99%, this is what other grinding mill can not reach.
3. Our raymond mill's driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.
4. The electric control system of raymond mill is centralized controlled, so the automatically is high, no people are needed in the operating room when the raymond mill is working.
5. Main parts of the whole plant are made from cast and steel of high quality. Such strict techniques insure the durability of whole plant.

Raymond Mill Working principle

Firstly, raw material is crushed by jaw crusher to the size required, and 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 of raymond mill 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 stuff is 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 airflow system is closely sealed up and circulated under condition of negative and positive pressure.
