After many years of practice and improvement, Raymond mill structure is getting perfect day by day. For low consumption, low investment, environment friendly , small occupation area, and more efficient than the traditional mill, it is widely used in the field of metallurgy, building materials, chemical industry and mining to process powder. The raymond mill is used in grinding the non-flammable and non-explosive stuff which has the Moh’s hardness below 7, humidity less than 6%, such as gypsum, talc, calcite, limestone, marble, feldspar, barite, dolomite, granite, kaolin, bentonite, bauxite, iron ore etc., the final products change from 613 micron to 44 micron.
Through the function of separator and blower, raymond mill can meet different customers’ demand. It has wide application 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.
Main working principle of this grinding machine:
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 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 set’s airflow system is closely sealed up and circulated under condition of negative and positive pressure.
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, etc. 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.
Overall attention that is needed for the grinder:
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.
