Use and structural characteristics of the mill

Edit:Zhangjiagang Leyu Yiyi Machinery FactoryUpDate:2019-08-12

The mill is widely used in the grinding of mineral products in the fields of metallurgy, building materials, chemicals and mining. According to the fineness of the material to be milled and the fineness of the material to be discharged, the mill can be divided into a pendulum mill, a high-pressure suspension roller mill, a high-pressure micro-powder mill, a straight-through centrifugal mill, and an overpressure trapezoidal mill. Powder mill, three-ring medium speed mill, six types of mills.
After the material is destroyed to the required particle size, the material is sent to the storage hopper by the hoist, and then the material is evenly connected to the Raymond mill main grinding chamber through the oscillating feeder. The grinding roller swings outward due to the centrifugal force effect during the rotation. Pressed against the grinding ring, the blade shovel the material between the grinding roller and the grinding ring, and the grinding intention is reached due to the rolling of the grinding roller. The fine powder after grinding of the material is brought into the analysis machine with the circulating wind of the blower for sorting, and the finely coarse material falls back to the regrind, and the qualified fine powder enters the cyclone powder collector of the product with the airflow, and is discharged through the powder discharging tube. It is a product. In the Raymond grinding room, there is a certain amount of moisture in the material to be ground, heat is generated during grinding, water vapor is transpiration, and the pipelines of the whole machine are not tightly connected. The outside air is sucked in, so that the circulating air pressure is increased to ensure the mill is under negative pressure. In the state of operation, the added air flow is discharged into the dust remover through the residual air duct, and is purified and discharged into the atmosphere.
Structural features 1, three-dimensional structure, small footprint, strong set, from the block material to the product powder independently into a production system; 2, the fineness of the product powder is uniform, the screening rate is 99%, this is other milling 3, the machine transmission device uses a closed gear box and pulley, the transmission is stable, reliable operation; 4, the important parts are selected high-quality steel, wear parts are selected high-performance wear-resistant materials, the machine wear resistance , reliable operation; 5, the electrical system uses centralized control, the grinding workshop can basically complete unmanned operation, and the maintenance is convenient.
Grinding machine Scope: The mill is used to destroy non-flammable and explosive mines, metallurgy, chemicals, building materials, etc. with a Mohs hardness of not more than 9.3, such as barite, limestone, ceramics, slag, and humidity below 6%. It is a high-precision flour processing of more than 280 kinds of materials. The particle size of the product is adjusted in the range of 80-425 mesh. The machine can produce 30-80 coarse powder by adding special equipment.
