The vertical sand mill has a very good refining effect on liquid paint latex paint, and materials with large particles can be ground to obtain finer materials. So under what circumstances do the larger particles refine the material to a good effect? What are the requirements for the material in the refinement process of the vertical sand mill?

1. When the material contains a lot of water, the material is likely to stick to the crushing cavity in the sand mill, and it is also easy to cause blockage during the conveying process after feeding, which reduces the crushing capacity of the sand mill. To solve this problem, the temperature of the material must be strictly controlled when selecting the material. If the temperature of the selected material is too high, sunlight or air drying can be used to reduce the percentage of moisture in the material.
Second, if you want to make the fineness of the crushed material very high, the smaller the sand making capacity is.
3. The more fine powder contained in the material before crushing, the more it will affect the crushing ability of the sand making machine to the material, because these fine powder are easy to be adhered and thus affect the transportation. Therefore, for materials with a high content of fine powder, a screening should be done in advance. Separate the fine powder from the material as much as possible to avoid affecting the processing capacity of the sand making machine.
Fourth, the greater the viscosity of the material itself, the easier it is to adhere. Materials with high viscosity will stick to the inner wall of the sand making chamber in the sand making machine. If timely and reasonable treatment is not carried out at this time, the processing efficiency of the sand making machine will be seriously affected. Therefore, when choosing materials, we must pay attention to the viscosity of the materials not to be too large.
