LUM ultrafine vertical roller mill is a new type of superfine grinding equipment developed by SBM, based on German ultrafine roll mill technology. It is mainly composed of a motor, reducer, roller grinding device, disk device, compression body device, separator, and gas station. The idea of reality is that it can complete the ultrafine powder grinding, grading and conveying operation with the right process parameters, mechanical properties and refined flour quality.
The main motor drives the disc to rotate by the reducer, at the same time the wind into the air from entering the LUM ultrafine vertical mill, material by screw feeder outlet falls in the center of the grinding disk, under the action of centrifugal force, the material from the disc center to the edge of the area, and after grinding roller grinding plate, grinding roller compacted, bulk the material directly crushed, fine materials by extrusion of material bed is formed after the inter particle crushing.
Crushed material continues to move to the edge of the grinding disc, strong air flow until the wind ring away, while the particles larger again fall to the disc to crushing, air materials through the upper part of the separator, the rotor blade under the effect of coarse particles, returned to the grinding wheel grinding, fine powder qualified with the air flow out of the ground, be powder collector system collection, powder was collected to obtain superfine vertical roller mill of a product. Mixed material of impurities such as iron to the disc edge with the movement of materials, due to its own weight and can not be blown up by the wind, falling to the ball mill grinding chamber is mounted on bottom of the scraper scraping slag discharge port discharge machine.
The LUM ultrafine vertical mill grinding process is carried out in the confined space. The difference with Raymond machine is the biggest traditional vacuum cleaner production is not positive pressure air supply production, thus effectively eliminate caused in the process of grinding dust.
Ultrafine vertical mill at present in domestic is mainly used for processing of coal, calcium carbonate and other minerals, mature production technology. In the production process, the failure rate is low, equipment intact rate can reach more than 98%, and high production efficiency.
Ultrafine vertical roller mill has high reliability, good stability, directly reduces the maintenance, repair, and thus directly reduces the cost of repair material expenditure. The normal production situation, vertical mill repair material cost is the most direct roll grinding, grinding and so easy to wear replacement and repair parts. But the roller wear to a certain extent, also can be turned to repeated use, to extend the using period of roll sleeve.
