Overview Of Raymond Mill↑

After many years of practice and improvement, the structure of Raymond Mill is getting perfect by low consumption, low investment, environment friendly, small occupation area, and more efficient than the traditional Mill.

The Application Of Raymond Mill↑

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, trona etc. The final size is between 613micron and 440 micron(0.613mmâ€

The Features & Benefit Of Raymond Mill↑

• The concrete base weight required is only 3 times of that of other similar machines thus the construction expenses is greatly reduced ;
• Small vibration while using and doesn't need shock-absorbing device;
• Large load adjustment scope, so it can run under various environments;
• Can bear very strong explosion pressure;
• The grinding roller adopts new material and new craft, which ensures long service life and low maintenance cost;
• There is gap between the grinding parts; it can start with load or offload.

Main Parts Of Raymond Mill↑

The Raymond Mill mill consists of motor, reducer, case, milling device, separator, outlet, coal feeding pipe, loading device, control box and sealing apparatus. The fittings are all of superior performance in the world at present. We ensure good quality and durability of the whole Raymond Mill machine.

Working Principle Of Raymond Mill↑

Firstly, raw material is crushed by jaw crusher to the size 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 stuff 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.

Maintenance Of Raymond Mill↑

1. Prior to installation of the equipment, all the people who will be assigned to operate the equipment have to be technically trained to know the principle and rules of operation. Someone should be specially selected and put in charge of the operation.
2. To ensure normal operation of the equipment, a manual containing strict rules and procedures for its operation, maintenance and repair should be well prepared and followed. Tools, replacement parts for maintaining, repairing and lubricating oil and grease must be available for immediate use.
3. After a period of usage, the equipment should be checked, to replace worn-and-torn parts such as rollers, rings and shovels. Be sure to fasten connecting-bolts, nut collars to fix rollers properly. Be sure to lubricate the parts sufficiently.
4. Roller should be replaced after 500-hours use. To check bearing in them and replace broken ones, and then fill enough oil and grease (with oil-pump or grease-gun).
