When we invest in vertical mills, the first is the selection process. Generally, when choosing, we will not only pay attention to its production capacity, but also pay attention to its quality, but when this high-quality equipment is used, it is inevitable The phenomenon of lower and lower output, then what is the reason for this phenomenon?
When the vertical mill is used, the decline in output is mainly caused by three factors, one is operation, one is wear, and the other is system performance. Let’s introduce these three factors separately:
This factor mainly refers to the feeding. If the vertical mill is producing, the feeding is unreasonable, which will cause obstacles to the production and reduce the production capacity, and the feeding is unreasonable, which mainly means that the properties of the added materials are not good. Meeting the production requirements of the mill, or the feeding speed exceeding the processing capacity of the machine, these are important factors that cause the production capacity to drop. For these phenomena, to ensure its production capacity, it is necessary to ensure reasonable feeding properties and continuous Uniform feeding speed.
When the vertical mill is in use, the internal parts will be worn to varying degrees. Generally speaking, the occurrence of wear will gradually reduce the performance of the parts. We know that the production of this machine is mainly assisted by different internal parts. If the performance of the parts decreases, it cannot assist the smooth progress of the production, and the production capacity will naturally decrease at this time. The wear of the parts of the pulverizer mainly includes the wear of the grinding roller and the lining plate of the grinding disc, the wear of the retaining ring, the wear of the nozzle ring, etc. The solution to these different wear phenomena is the degree of daily maintenance to delay the wear. When the wear is serious Time, timely replacement, in order to restore the performance of the mill.
This mainly includes two aspects, one is the phenomenon of air leakage in the system, and the other is the change in the thickness of the material layer. The former will cause the change of the pressure difference inside the vertical mill, so that the ground material cannot be taken away in time, which affects the air volume. And this phenomenon will also cause the blockage of the air duct, which is very unfavorable for production. For the change in the thickness of the material layer, if the material layer is too thin, the grinding stress is too concentrated and the grinding capacity is reduced, which will also cause the mill.
Large vibration and damage to the lining plate and tension rod. In addition, if the thickness of the material layer is too thick, the grinding force will be converted into lateral stress, sliding shear will also be formed between the materials, the slump of the material bed will increase, and the grinding efficiency will decrease. At the same time, the vibration of this series of pulverizers will be increased, whichever one is unfavorable for production.
The article mainly introduces how the output of vertical mill is getting lower and lower? For the introduction of this problem, the above analysis is more detailed, mainly due to three reasons: operation, wear, and system performance, and a detailed analysis of these three aspects is carried out. In the actual use process, the impact on the The factor of output needs to be dealt with in time to ensure the output of the pulverizer to ensure the customer’s investment income.
