There are many ore materials processed by Vertical Roller Mill. In order to respond to the national energy conservation and emission reduction call, many industries currently use vertical mills for processing, thus achieving the effect of energy saving and emission reduction. There are many types of micro-grinding materials. The powder sorting machine, the grinding roller device, the grinding disc device, the pressing device, the reducer, the motor, the casing and the like are composed. The rotary part of the ultra-fine classifier is the core component of the classifier. The dynamic balance will directly affect the performance, output and service life of the classifier.
When the vertical mill is used to process limestone materials, the centrifugal type separator is used in combination with the sand making line. The traditional sand washing machine wastes natural resources, although the economic benefits can be guaranteed, but the environmental benefits are poor. However, the use of a screening machine has a complicated structure and requires frequent replacement of the screen, which is complicated in steps and labor-intensive. The influence of the ultra-fine classifier on the working condition of the mill is mainly reflected by the power class of the powder, the cycle load rate and the grinding power of the mill. The influence of excessive stone powder content on cement and asphalt concrete volume parameters have important significance for the performance of asphalt mixture.
During the working process of the Vertical Roller Mill separator, the material enters the classifier from the feed port, passes through the inner cavity into the throwing disc, and then passes through the centrifugal action to the inner chamber of the classifier. The large blade provides updraft, coarse The material is blocked by the auxiliary blades and discharged from the coarse feed port. The fine material is taken up by the ascending airflow to the outer bin. When it reaches the return air blade, it enters the inner bin along the gap of the return air blade to form a circulating airflow and can be sorted three times, and a small part of the fine powder is discharged from the fine powder port. The complete set of equipment can not only increase production, but also improve the quality of pulverized coal and stabilize the thermal system.
