Coarse grinding, Raymond mill and ultra-fine grinding
Milling equipment from the finished product can be 40-80 mesh fineness called the coarse powder mill, 80-325 mesh commonly known as Raymond mill, 100-2500 mesh is called ultrafine mill, focus today Under the coarse powder mill, coarse grinding is the combination of customer needs, based on the traditional mill, designed coarse grinding equipment, coarse powder mill to solve the user fineness of 3 mm below the finished product mix A demand for materials.
In the process of coarse grinding instead of Raymond mill, grinder, ultrafine mill and other traditional milling equipment can only process fine powder particles of a new high-tech products to meet the requirements of the meal processing, which is widely used In the quartz sand, silica sand, sand casting, abrasive abrasive sand and other fine sand industry, a high-efficiency ideal equipment composed of closed-circuit production line, can produce a variety of particle size products, the use of a wider range of better results. After the coarse flour mill into the market is very popular with industry customers, and make up for the other can only process the lack of machinery powder. It should be noted that the coarse powder mill is improved from the Raymond mill, the general mill can be about 1 millimeter of coarse powder, like 20 mesh -80 purpose powder can easily be processed to meet the rough The needs of powder market users, especially for the highway, refractory materials, building materials, water and oil in the area of some coarse flour mixture market, especially suitable. The characteristics of the coarse powder mill is the fineness of the range can not be adjusted, after the manufacturers set, this range can not be changed, compared to Raymond mill, a reduction of a link, so greatly enhance the yield. Coarse grinding with high production capacity, crushing ratio; low power consumption, product size coarse; simple structure, easy operation; small investment costs, is currently a rare coarse meal mill coarse grinding machine. In the metallurgical, mining, chemical, cement, coal dry stone, construction, sand making, refractory and ceramics and other industrial and mining enterprises, engaged in the material meal operations, mainly suitable for crushing compressive strength of not more than 320MPa (MPa) Soft and hard ore. During the operation of the coarse powder mill machine, the motor drives the roller hanger to rotate through the triangular pulley and the central shaft, and the grinding roller mounted on the roller hanger through the bearing and the cross arm shaft rotates with the roller hanger, Rolling along the grinding circle. Joined into the feed hopper bulk material through the three pan, three powder cone, evenly along the circumference fall between the grinding ring and the grinding roller, grinding roller crushed from the bottom discharge. Dust fan is the import and export of the mill to form a negative pressure, no dust pollution, while the heat discharged from the machine.
