Henan Sinoma how to choose Raymond Mill and ultrafine mill?

First, introduce the difference between Raymond Mill and Ultrafine Mill.

 

    Raymond Mill is widely used in barite, calcite, potassium feldspar, corundum, silicon carbide, talc, marble, limestone, dolomite, fluorite, titanium dioxide, lime, activated clay, activated carbon, bentonite, kaolin, cement , phosphorus ore, iron oxide, gypsum, glass, light calcium carbonate, coal dry stone, pulverized coal, carbon black, clay, insulation materials, Mohs hardness of not more than 9.3 , non-flammable and humidity below 6% Explosive minerals, chemicals, construction and other industries more than 280 kinds of materials, high - preparation milling process, R -type Raymond Mill finished particle size of 80-325 mesh within the scope of any adjustment, some materials up to 600 mesh.

    The ultra-fine grinding machine is a new series of successful grinding machines developed by our company. It is mainly suitable for the grinding and crushing of conventional materials such as kaolin, limestone, calcite, talc marble, Barite, gypsum, red iron oxide, iron oxide green, aluminum hydroxide, pigments, bentonite, clay and other humidity less than 8 %, high hardness <6 materials, fineness can reach 500-1250 mesh ( 0.025mm -0.01mm ), special materials up to 2500 mesh (0.005mm) or more.  

    Ultrafine grinding mill working process: After a large piece of material broken by the hoist into the storage warehouse, and then by the electromagnetic vibration feeder evenly into the host grinding room, the material into the mill room shovel shovel, enter The roller and the ring are crushed and smashed. The fan blows the wind into the grinding chamber, blows the powder into the analyzer, sorts it, and can not reach the fineness again and falls into the grinding chamber again. The qualified fine powder is With the airflow into the finished cyclone collector, the fine powder is separated from the air and discharged from the discharge port, which is the finished product. The air returns from the upper return duct to the fan. The air circulation is cyclic and flows under negative pressure.

    In the grinding chamber, because the material to be polished has a certain amount of moisture, when it is ground, it will generate a certain amount of heat to cause the water vapor to evaporate, and the flange connection seal of the entire pipe is not tight enough to inhale the outside air, so that the circulation air flow is increased. Ensure that the mill works normally under negative pressure. The increased air flow is discharged into the bag filter through the residual air pipe between the fan and the host, and is purified and discharged into the air.

   When customers purchase milling equipment, they must be aware of their own production needs, especially the fineness of materials; if the processing fineness is less than 325 mesh, Raymond milling equipment can be used; if the processing fineness is 300 Above, after selection of ultra-fine grinding equipment.
