The main motor drives the grinding disc through the reducer, while the hot air enters the broken body from the inlet, and the material falls in the center of the grinding disc through the inlet. Under the action of centrifugal force, the material moves evenly from the center of the grinding disc to the edge. When the grinding disc is grinding the roller table area, the roller is crushed and the bulk material is pressed directly. Crushed and fine materials are extruded to form a material bed for intergranular comminution. The crushed materials continue to move to the edge of the grinding disc until the strong airflow is taken away by the wind ring. In the material taken by the airflow, the larger particles are re dropped to the grinding disc under its own gravity, and the rest of the materials enter the high efficiency dynamic separator into the powder classification, and in the efficient dynamic separator with the air flow. Under the action of the blade, the material that does not meet the requirements of the fineness is returned to the grinding disc for grinding. The material that meets the requirements of the fineness is collected in the pulse dust collector with the gas flow through the pipe, and the finished powder is discharged through the discharging device. When the refractory debris, such as iron, mixed with material in the host, moves to the edge of the grinding disc, it can not be blown by the wind because of its own weight, and the scraper plate which is installed in the bottom of the mill is scraped into the slag outlet at the bottom of the grinding disc and expel the outside of the main engine.
LUM series superfine Vertical Roller Mill is a new type of ultra-fine grinding equipment designed and developed on the basis of many years of mill production, based on the common Vertical Roller Mill, using the new Taiwan grinding roll technology and the German powder selection technology. LUM series superfine Vertical Roller Mill s has been set up for ultra-fine grinding, classification and transportation of superfine Vertical Roller Mill, and has become an equipment for ultrafine flour milling industry.。
The models of LUM series Vertical Roller Mill are LUM1125, LUM1232 and LUM1436. Fineness of the finished product: 400-800 orders (D97) for one time and 800-2000 orders for two powder selection; the grain size of the finished product is less than 2 mu m as high as 70%, and the processing ability: 5-18t/h, equivalent to 4-5 micro milling. All kinds of models are controlled by PLC/DCS automatically, so as to achieve unmanned operation. Besides, LUM series Vertical Roller Mill adopts thin oil lubrication system, greatly reducing downtime and lubricating oil consumption. LUM series Vertical Roller Mills are equipped with wearing parts of high-performance materials, and extend the service life of equipment. [see specification parameter table for specific technical parameters]
[feed granularity]: <10mm;
[production capacity]: 5-18t/h;
[application]: the Vertical Roller Mill is widely used in chemical industry, metallurgy, nonmetal mine and other industries.
[applicable materials]: Moir hardness below 5, density below 3.2, compressive strength below 150Mpa, non flammable explosive ore, non corrosive brittle material granular and powdery material. Such as limestone, calcite, talc, barite, dolomite and other nonmetallic minerals.
When the Vertical Roller Mill works, the material falls in the center of the grinding disc through the spiral feeder, and the centrifugal force produced by the reducer to drive the grinding disc is driven by the main engine, so that the material moves evenly around the grinding disc. When the material passes the roller track on the grinding disc, the roller is crushed and the large pieces of the material are crushed directly. The smaller particles are subjected to the material. After extrusion, the material bed is formed to comminution between particles.
After being crushed, the material continues to move to the edge of the grinding disc, and is graded by the air flow from the inlet of the inlet to the pulverizing machine. Under the action of the blade of the pulverizing machine, the powder that does not conform to the particle size requirement falls into the grinding disc and regrinded, and the standard powder is collected through the pulverizing machine and the pulverized dust collector is collected and collected. The body is the finished powder. The iron and other impurities mixed in the material, because it is difficult to grinding and its own gravity, through the edge of the grinding disc, can not be taken away by the air flow into the mill lower cavity, the scraper plate is sent to the spit mouth, and the outside of the main engine is discharged.
LUM series Vertical Roller Mill is equipped with automatic control system, which enables remote control and simple operation. At the same time, the Vertical Roller Mill adopts PLC/DCS automatic control method of grinding roller pressure, precise control of grinding pressure and no manual operation.
The equipment adopts the principle of Vertical Roller Mill layer grinding, the retention time of the material in the grinding is short and the repetition grinding is reduced, so the iron content in the product is very few, and the brightness and purity of the product are high. The particle size of the product with a particle size less than 2 mu m can reach 70%, which achieves 325 orders of low residue and can increase two times of powder selection, and select more fine-grained products.Learn More
