The mill structure and working principle of analysis

With the expansion of the mill of the scope of application, the working principle and structure of vertical mill also reminded everyone to explore interest. The working principle and structure today Tongli heavy machine to introduce vertical mill, to help you quickly understand the use of vertical mill.

The main structure of vertical mill by the separator, grinding roller device, a grinding table device, a pressure device, reducer, motor, shell and other components. The separator is an important part of decision milling product thickness, comprising a driving device, a speed adjustable guide vanes, rotor, casing, coarse powder blanking cone outlet, etc., is a kind of powder selecting device, energy saving, fast and efficient. The grinding roller is the main component of rolling grinding of materials, it is loaded in a bent arm grinding machine, under the action of external force, pressed in the disc materials, driven by a millstone, then transferred to the grinding roller, so that the material is compacted and crushing. Grinding disc is fixed on the output shaft of the reducer, the upper millstone for bed, with an annular groove material bed, the material is in an annular groove is roll grinding crushed. Provide milling pressure grinding roller component pressurizing device, which is composed of high pressure oil station, hydraulic cylinder rod, an energy accumulator and the like, can exert enough pressure to make the material crushing and grinding roller. The speed reducer is the main power transmission components, grinding disc speed reducer output pumping speed is.

Working principle: motor driven vertical mill reducer rotating disc through, at the same time, the hot air can enter from the air inlet vertical mill, the material from the feed opening falls on the disc center, due to the centrifugal force, the material is moved from the center to the edge of the grinding disc disc, the disc mill by an annular groove, the grinding roller compacted by shattered, crushed material continues to move to the edge of the grinding disc, until the wind ring away, and the large particles and fall into the disc to crush. In a flow of materials through the upper part of the separator, guide blades under the action of the cone bucket fell, crude material from a disc, a fine powder with air toghter grinding, dust collector is the collection, the powder is collected is the vertical mill of a product. The material is in contact with the shell in the process of drying gas, achieve humidity dry products required. By adjusting the separator guide blade angle small mill irreconcilable separator rotor speed, can achieve the required thickness of products.
