Combined with special high-quality cast steel components and durable wear parts,our Raymond Mill is capable of exceptionally high crushing availability,cost-efficient crushing and low energy consumption.
The Raymond mill are mainly applied to crush the barite,limestone,ceramic,slag with the Mohs hardness of less than 9.3 degree and the super thin powder process of over 280 materials in the non-flame and explosive field of mining,metallurgy,chemicals with the moisture of lower than 6%. And the final particle size can be adjusted at the range of 80—325 monyh.
Structure features of Raymond mill
Main structure of Raymond mill
Main structure of the Raymond mill are including the main machine body,analyzer,wind machine,final products classifier,fine powder classifier and the wind pipes .And the main machine body are including the frame,inlet shell,shovel,roller,grinding ring,and the cover.
Working principle of Raymond mill
The materials will be delivered into the machine body by the feeding hopper installed on the sidewall of the cover shell. Abiding by the roller equipments swung on the star rack of the main machine body,it will make the revolution movement by surrounding the vertical axis and make the autorotation movement at the same time .Due to the centrifugal force,the roller will swing outside and give much pressure on the grinding ring so that the shovel can deliver the materials to the space between the roller and ring,thus achieving the crushing aims.
Wind classifying process of Raymond Mill
After the grinding,the wind machine of the Raymond mill will blow the wind to the main units shell and blow up the powder to the analyzer positioned upon the grinding room to receive the classifying .While the materials with over-coarse degree will fall down to the grinding room to receive the repeated grinding .And the standard particles will flow to the cyclone collector along with the wind stream and then be discharged out by the discharging gape at the form of final products. And the wind stream will return the wind machine by the return air positioned on the upper end of the large cyclone collector .And the air course is circular and can flow at the negative condition. And the wind increasment of the circular wind path will be discharged out by the waste air pipe between the wind machine and main units. And then it will enter the small cyclone collector and proceed the purifying processing.
Raymond Mill's Technical Data
Raymond mill or Raymond grinder is widely utilized to grind non-flammable and non-explosive elements like barite,calcite,potash feldspar,dolomite,gypsum,talcum,mica,marble,limestone,kaolin,clay,coal and so forth. It is actually ever the mainstream grinding machine in powder producing sector.
