Raymond mill

Application of Raymond mill / Raymond grinder

The machine is used for grinding the barite, limestone, kaolin, porcelain clay, and slag, etc, below scale 9.3 of Mohs hardness and 280-odd sorts of non-inflammable and non-explosive stuff in the trades of mining, metallurgical industrial, chemical engineering and building material for high fine powder generation and processing. The product size is adjustable in the range of 80-325 (600 the largest) meshes. It is possible to product 30-80 mesh coarse powder through special device in the machine.

Main fittings of Raymond mill

The Raymond 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.

The features & benefits of Raymond mill

a. The concrete base weight required is only 3 times of that of other similar machines thus the construction expenses is greatly reduced;

b. Small vibration while using and doesn't need shock-absorbing device;

c. Large load adjustment scope, so it can run under various environments;

d. Can bear very strong explosion pressure;

e. The grinding roller adopts new material and new craft, which ensures long service life and low maintenance cost;

f. There is gap between the grinding parts; it can start with load or offload.

Working principle of Raymond mill

When it is put into use, the materials to be grinded are put into the main frame through the feed-in bin on the side cover. Then it revolves round the vertical axis line by the milling roller hung on the star rack. With the centrifugal force by rotation, milling roller wings outside and presses fast on milling rings to make relieving tool carry materials between milling roller and ring, thus the materials are crushed by the rolling and milling of the milling roller.

Little common knowledge on 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).

Raymond grinder, Raymond mill for sale

The Raymond grinder (Raymond mill) is rather versatile and the Raymond grinder (Raymond mill) can be used to grind barite, calcite, kalium, steatite, marble, glass, feldspar, ect. Raymond grinder (Raymond mill) is widely used in the metallurgy, building, chemical industry, mine field. In the chamber of Raymond mill, since the stuff of Raymond grinder (Raymond mill) may contain moisture to some extent, the heat generated during makes the moisture evaporated. Raymond grinder further functions may involve drilling, boring or slot producing. Raymond mill can be broadly described as the process of reducing the material to finer size though Raymond mill is different from crushing and granulation.
