Introduction to Raymond Mill
As a major grinding manufacturer , China Mining equipment Co., Ltd. have developed this new kind of suspension grinder with strong pressure on the basis of international advanced technology .And the Raymond Mill also have some relative names ,such as new energy-saving Raymond Mill ,pendulum Raymond Mill equipment, super thin suspension grinder ,etc. And this kind of Raymond Mill can be applied to the powder manufacturing with high-pressure and closed circuit in the field of small mines,chemicals, building materials, metallurgy, etc. And the Raymond Mill has found its extensive application to crush the non-flammable and explosive materials with the Mohs of lower than 7degree and moisture of below 6% ,such as quartz, feldspar, calcite, talc, barite, fluorite, rare earth, marble, ceramics, bauxite ore, iron ore, copper ore, phosphate rock, iron oxide red, slag, slag, cement clinker, activated carbon, dolomite, granite, iron oxide yellow, bean cake, chemical fertilizer, fertilizer, coal, coke, lignite, magnesite sand, chromium oxide green, gold, red mud, clay, kaolin, coke, gangue, porcelain clay, swelling Run soil, medical stone rhyolite, leaf wax rock, shale, purple stone, Diego rock, basaltic rock gypsum, graphite,etc. And the final particle size range of the Raymond Mill can be adjusted by the specific requirements (0.125-0.044 amount to 100monyh-325monyh ).
Working principle of Raymond Mill
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 unit by the 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 be graded 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 the air stream will be absorbed by the wind blower on the upper end of the large cyclone collector .And the whole air stream system of the Raymond mill is closed circulation and will proceed the circulation under the positive and negative condition.
Products advantages of Raymond Mill
1) The technical advantages of the Raymond Mill: developed by China Mining equipment Co., Ltd., the Raymond Mill with large, middle, small type energy-saving have adopted the modern design manners and taken the advanced crushing theory as the guidance. And the design of grinding roller is installed on the both end of the star rack central axis , which can make the grinding roller situated in a natural and balanced condition. And the main unit has been proceeding the well function with small vibration.
2) The occupation area grinding roller have covered in the cavity of the main unit is small so that the working space will become larger .And then the high-pressure wind of the blower will reach larger working area so that the fine powder have more chances to get out of the main unit and enter the cyclone collector ,which can avoid the repeated grinding of the super-thin powder with no efficiency. And that’s the reason that the output of the new type Raymond Mill with energy-saving is higher than the traditional Raymond Mill with three grinding rollers .
3) the new type Raymond Mill with energy-saving only has two grinding roller with lower working load ,which can save the energy by 25% and improve the output by 20% than the traditional Raymond Mill with three grinding rollers. And the the new type Raymond Mill with energy-saving adopt advanced technology and also have created the considerable economic benefits for more than eight hundred of clients.
Main structures of Raymond Mill
The main structure of Raymond Mill are including the main machine body ,analyzer ,wind machine ,final products classifier ,fine powder classifier and the wind pipes .And the main unit of the Raymond Mill are including the frame ,inlet shell, shovel ,roller ,grinding ring, and the cover .
