Vertical Roller Mill

Transcription

1 Vertical Roller Mill Introduction The Vertical roller mill produced by our company is devoted to the resolve of energy-consumption in the industrial grinding mill. And after years designing and development, we first-class expert have developed this kind of new grinding equipment with high-efficiency and wide application. And the Vertical roller mill have also adopt the novel powder grinding principle,reasonable structure and high anti-abrasion alloy materials.and this kind of Vertical roller mill have absorbed many kinds of powder manufacturing technology and every performance of the Vertical roller mill have greatly over the traditional powder grinding equipment,particular to the materials with high hardness and processing. And this kind of Vertical roller mill can be processed by two ways of with or without the moisture.

2 This kind of Vertical roller mill have found their extensive application in the field of fertilizer, mining, building materials, chemical industry, metallurgy, thermal power, nonmetal, abrasive, brick, ceramic, steel, coal, etc. And the Vertical roller mill can also be used to crush the block materials into the coarse powder ( fine powder, the mixture of fine and medium sand ), such as cement (raw clinker), quartz, feldspar, calcite, gypsum, limestone, coal gangue, slag, talc, granite, feldspar, marble, barite, ceramics, glass,etc. And these are all high, medium, and low hardness materials with the Mohs hardness of below 9.5%. Working principle of Vertical roller mill During the operation of the Vertical roller mill, the reducer installed on the top of the main units will rotate with the central axis connected with the couplings. And then the central axis will drive the grinding roller cradle to rotate and the grinding roller installed on the cradle will roll around the inner surface of the grinding ring. And the materials will enter the feeding hopper from the side top of the machine and then be divided into two parts. And then the materials will scatter around the distributing plate which rotate with the central axis and then will be evenly entered the space between the grinding ring and roller along with the circle tunnel. And at last, the materials will be grinded and crushed by the roller and then be discharged by the outlet. Structure features of Vertical roller mill

3 Main structures of LM series Vertical roller mill are including the classifier, roller,plate, pressure,reducer, motor, shell equipment and so on. The separator is a kind of high-efficient and energy-saving equipment.and the roller is a kind of spare parts used to grind and crush the materials. And the pressure equipment is a kind of spare parts providing the pressure for the grinding roller, thus crushing the materials.the plate is installed on the output axis of the reducer, which is the place the materials is crushed by the roller. Technical advantages of Vertical roller mill The Vertical roller mill adopts novel principle of roller pressure powder grinding and the scientific design. And the Vertical roller mill have also absorbed multi-pregrinding technology and have the prominent advantages than the traditional Vertical roller mill, fine crushing mill, roller pressure and other kinds of impact crusher,which have really realized the pregrinding technology s high-efficiency,energy-saving and environment-friendly. 1. Short stay in the Vertical roller mill; the regrinding time will be reduced and the products quality is stable. 2. This kind of Vertical roller mill can adjust the hot wind temperature and features high dryer capacity and energy-saving. 3. The roller shaft and grinding plate of the Vertical roller mill have been

4 installed the anti-direct touch equipment, which can avoid the destructive impact and strong shaking. 4. With the compact structure, The Vertical roller mill have integrated the dryer, powder grinding, and grading into a single whole. 5. The roller and the plate of the Vertical roller mill adopt the quality materials, which have reduced the wearing consumption and expand the service life. 6. The equipment of Vertical roller mill has the whole sealing system, which have realized the function under the negative pressure, no dust and environment pollution. 7. The Vertical roller mill features better mechanical performance, simple operation, convenient maintenance, low wearing parts and long service life.
