      Graphite ultrafine mill

      Graphite ultrafine mill

      Product introduction:

      Processing graphite can choose the mill equipment: YGM high pressure suspension roller Raymond mill : processing fineness between 15-425 mesh (fineness can be adjusted freely), HGM three-ring medium speed superfine mill : processing The fine


      Product description


      Graphite use:
      Graphite is a hexagonal or trigonal scaly crystal or massive aggregate, lead gray, opaque, semi-metallic luster, density of 2.09-2.23g/cm3, with a slippery feel, easy to dye hands. Graphite is a special non-metallic material with excellent properties of metal, coating, lubricity, high temperature resistance, corrosion resistance, acid and alkali resistance, plasticity, thermal conductivity, electrical conductivity, chemical stability and high temperature. Special heat resistance, graphite has a small coefficient of thermal expansion and is a light mineral known to withstand high temperatures. 
      Graphite has the distinction of crystalline graphite and earthy graphite. The use of earthy graphite is narrow. It is mainly used as a refractory material, and it is used to manufacture functional cement materials and non-metal electric heating elements. Because of its difficulty in sorting, it has a taste for development and utilization. Higher, the cut-off grade is fixed carbon content greater than 55%, industrial grade is fixed carbon content greater than 65%; crystalline graphite can be used as refractory material, hot metal forming material, conductive material, wear-resistant material, lubricant, sealing material, Corrosion-resistant and high-temperature materials, environmental protection materials, radiation protection materials, military and aerospace materials.

      Graphite mill, graphite mill machinery:
      Processing graphite can choose the mill equipment: YGM high pressure suspension roller Raymond mill : processing fineness between 15-425 mesh (fineness can be adjusted freely), HGM three-ring medium speed superfine mill : processing The fineness is between 325-3000 mesh (the fineness can be adjusted arbitrarily), and the fineness of the European version of the coarse powder milling machine is less than 3mm.
      Graphite mill can not only process graphite, but also ultra-fine powder processing of non-inflammable and explosive brittle materials with medium and low hardness and Mohs hardness ≤6, such as calcite, chalk, limestone, dolomite and carbon black. , kaolin, bentonite, talc, graphite, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomaceous earth, barite, gypsum, alum, graphite, fluorite More than 100 kinds of materials such as phosphate rock, potassium ore and pumice.

      Working principle of graphite mill


      Complete set of graphite mill includes hammer crusher, bucket elevator, storage bin, vibrating feeder, micro-grinding host, frequency classifier, double cyclone dust collector, pulse dust removal system, high pressure fan, air compression Machine, electrical control system. According to the needs of users, it can also be equipped with auxiliary equipment such as crusher, hoist, storage bin, electromagnetic vibrating feeder and electrical control cabinet. Users can equip ascending, storage silo, electric control cabinet, electromagnetic powder feeder, and crushing according to needs. Machine and other auxiliary equipment.
      After the bulk material is crushed, it is sent to the storage bin by the hoist, and then the electromagnetic vibrating feeder is evenly sent into the main machine grinding chamber. The material entering the grinding chamber is scooped up by the blade and is rolled between the grinding roller and the ring. Pressing and crushing, the fan blows the wind into the grinding chamber, blows the powder into the analysis machine, sorts it, and does not reach the fineness of the grinding chamber. The qualified fine powder enters the finished cyclone collector with the airflow. After the fine powder is separated from the air, it is discharged from the discharge port, and the air is returned to the fan from the upper return air duct. The air path is circulated and flows under a negative pressure state. In the grinding chamber of the ultra-grinding mill, due to the certain moisture content of the material to be ground, a certain amount of heat will be generated during the grinding to cause the water vapor to evaporate, and the flanges of the whole machine are not tightly sealed, so that the outside air is sucked in, so that the circulation The airflow increases, in order to ensure the normal operation of the mill under negative pressure, the increased airflow is discharged into the baghouse through the residual air pipe between the fan and the main engine, and is purified and discharged into the air.

       


      Performance Characteristic


      1. High efficiency and energy saving
      In the case of the same fineness of the finished product and the same motor power, the output of the jet mill, the agitator mill and the ball mill is more than double.
      2. Consumable parts have long service life
      The grinding roller and the grinding ring are forged by special materials, so that the utilization degree is greatly improved. In the case of the same material and finished product fineness, the wear life of the impact crusher and the turbo crusher is 2-5 times longer, generally more than one year. When processing calcium carbonate and calcite, the service life can reach 2 -5 years.
      3. High safety and reliability
      Since there is no rolling bearing or screw in the grinding chamber, there is no problem that the bearing and its sealing member are vulnerable, and there is no problem that the screw is loose and the machine is destroyed. 4. High product fineness
      The product fineness can reach D97≤5μm at one time.

      5. Environmental protection, cleaning The dust collector is used to capture dust, and the muffler is used to reduce noise. It is environmentally friendly and clean.
