AUTHOR: admin DATE: 30 May 2012 05:14:19

The technological process of powder grinding has an indispensible significance to the industrial development; especially that it has a wide application in building materials, coal mining and rocks powder manufacturing aspects. For this reason, the technological performance of the grinding mill has attracted a lot of attention from many mining machinery manufacturing companies.

Raymond mill

Raymond mill (Raymond roller mill) is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry and metallurgy, such as barite, calcite, feldspar, talcum, marble, limestone, clay, glass. The fineness of the finished product can be adjusted from 100 meshes to 325 meshes according to requirements. It is the main and widely used grinding machine.

Raymond mill belongs to a large sized powder grinding machine, the material feeding size can be below 100 mm, and the materials after being ground is able to go through the finest screen and the production ability generally reaches more than one tone an hour.

The Raymond mill can crush the large-size materials to the required feeding size and then will deliver the materials to the storehouse by the dustpan lift, which will be evenly delivered them to the crushing cavity of the main machine body by the electromagnetism vibrating feeder. And the materials which have entered the grinding cavity will receive the grinding between the grinding roller and ring, thus producing the powder, which will be brought to the analyzer to grade by the wind machine. And the required fine powder will enter the large cyclone collector by the air stream to receive the separation and collection .And at last ,the final products will be discharged out by the tripper .And during the working process, the shovel system have played a key important role ,which is positioned on the lower end of the grinding roller .And the shovel and roller will shovel up the materials to the space between the grinding rollers and form the pad layer which will receive the extruding force produced by the rotating of the rollers .And then the materials will be crushed ,thus achieving the aim of the powder making.

The Raymond mill is very suitable for the production of dry powder. The base plate, grinding roller and grinding ring of the machine are all made of steel so that steel materials are mixed with the grinding material which adds the steel removal difficulty. In addition, this equipment needs high plant and wide size. The type of grinding mill unload products with the help of the wind, for this reason, during the whole operational process, the dust prevention work should be done well. And what is more, because of its working features, the Raymond mill can never be started in an empty state.
