LUM superfine vertical mill is developed by Shanghai Yingyong based on the ultra-fine vertical mill, combined with years of experience in mill research and manufacturing. It is a device specially used in the ultrafine grinding industry, which can realize the functions of ultrafine grinding, grading and conveying. It is widely used in chemical industry, metallurgy, non-metallic minerals and other industries.
LUM ultra-fine vertical mill is mainly composed of electric motor, reducer, grinding roller device, grinding disk device, pressurizing device, powder separator, body and oil station.
Materials: coal, mica, talc, graphite, quartz stone, limestone, dolomite, kaolin, coal gangue and more than 200 kinds of materials
Application fields: chemical industry, metallurgy, mining, non-metallic mines and other industries.
The main motor drives the grinding disc through the reducer, while the wind enters the vertical mill body through the air inlet. The material falls into the center of the grinding disc through the downward feeding port of the screw feeder, and under the action of centrifugal force, the material moves evenly from the center to the edge of the grinding disc. When the material passes through the grinding roller channel area on the grinding disc, it is crushed by the grinding roller, and the large pieces of material are directly crushed.
The material being ground continues to move towards the edge of the grinding disc until it is brought away by the strong airflow at the wind ring. Larger granular will fall back onto the grinding disc for further grinding. Under the influence of the rotor blades, as the material in the air stream passes through the upper separator, the coarse particles return to the grinding disc again for grinding. The qualified fine powder comes out of the mill together with the air stream and is collected by the system's powder collector, and these collected powders are the products ground by the vertical mill.
In the process of material movement, impurities such as iron blocks in the material will reach the edge of the grinding disc along with the material. Due to their heavy weight, they cannot be blown up by the wind, so they will fall to the lower cavity of the mill, and will be scraped into the slag discharge port by the scraper, and finally discharged out of the machine.
By adjusting the rotational speed of the rotor of the multi-head separator, we can obtain different fineness qualified products. In addition, by adjusting the pressure of the hydraulic system, the pressure of the roller mill can be adjusted to accommodate raw materials of different hardness.
