How to improve the production quality of vertical roller mill

Article source:admin Popularity:Dateline:2020-03-16 16:19

Relative to the price, the quality of the materials produced by the vertical roller mill is also very important. So how to improve the quality of the materials processed by the vertical roller mill?
 
The first is the particle size of the raw materials. The particle size of the raw material cannot exceed the size required by the index of the vertical roller milll. If it exceeds, the output particle size of the material will be too coarse, because the production capacity of the vertical roller mill is limited and cannot exceed the required particle size The size of the indicator. And when other conditions are kept unchanged, the raw material is coarser, the coarser the particle size of the produced powder, the finer the raw material, the finer the particle size of the produced powder. The hardness of the raw materials is also limited. The hardness of the raw material also affects the quality of the vertical roller mill machine. When other conditions are unchanged, when the hardness of the raw material is too large, the output particle size of the powder will be relatively large and the quality will be reduced.
 
In addition, in the production process, if the amount of raw materials is too large, the material will stay in the vertical roller mill for too little time. If the time is too small, the material will not be ground enough, so that the powder output will be insufficient. The particle size will be too coarse, and the production quality will be reduced. Therefore, in the production process, the amount of material to be controlled should be controlled. According to the production performance and model size of the vertical roller mill, the amount of input should not be too much or not.
 
Also, when the diameter of the steel rods in the vertical roller mill is too large, the gaps between the stacked steel rods will be larger, and the material flow rate will be faster, so the grinding time of the material will change. Short, this situation will also reduce the contact surface between the material and the grinding body, which will lead to insufficient grinding, so the diameter of the vertical roller mill steel rod should not be too large.
 
Then, when the speed of the vertical roller mill is too low, the impact force on the steel bar will be smaller, which will reduce the production capacity of the vertical roller mill, which is suitable for fine grinding. When the speed of the vertical roller mill is too high, the impact force on the steel rod will be greater, which is conducive to rough grinding. Therefore, to achieve different production granularity requirements in production, we must first adjust the speed to achieve the desired production quality.
