Raymond Mill/Micro-powder Grinder/High Pressure Micro-powder Mill/Raymond Mill Manufacturer

Progress compared with traditional mill

After many years of practice and improvement, Raymond mill's 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 series 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, it can meet different customers’demand.



Raymond mill is used for grinding the barite, limestone, kaolin, cerames, ahd slags, 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.


Performance characteristics of high-strength raymond mill, sand maker :

Raymond mill is used for ultra-fine powder processing of 280 materials, with the Moth's hardness of 9.3 below and humidity of 6% below, in the works of non-flammable mine, chemical industry and building materials, etc. The materials include barite, calcite, potash feldspar, pencil stone, marble, dolomite, fluorite, limestone, active carbon, bentonite, etc.

The particle size of finished product can be adjusted from 80-325 meshed. And it can reach 2000 meshed at the maximum.

High pressure suspension mill working principle:

In the main frame, a 100-1500 kg powered pressure spring is fixed to the roller suspender. After the grinder is put into effect, the roller rotates around the main shaft, and rolls closely against the ring pressed by the high pressure spring and centrifugal force. And its rolling pressure ration is 1.2 times higher than that of the raymond grinder under the same power condition and the production output is raised to substantial degree.

When a certain degree of wear of roller and ring is effected, it is recommended to adjust the length of the spring to maintain the constant pressure between the roller and the ring. As a result, the stable output and fineness are ensured.
