Silica has high hardness and high whiteness. The selection of the pulverizer is very important for the quality of silica powder in the milling process. It is very important to select a suitable mill, which can not only improve the performance of silica powder, but also prevent the equipment from failure and have a longer service life. A set of high-quality silica powder can greatly increase the efficiency of silica powder. How to choose the grinding equipment for processing silica powder?
First of all, consider the hardness of silica. The hardness range of the selected mill should be about Grade 9. The traditional Raymond mill generally requires hardness below Grade 6, so it is not suitable for the grinding of silica powder. The materials processed by MTW trapezoidal mill, vertical mill and other equipment can reach Grade 9, and the output is large and the efficiency is good. Therefore, the powder ground by this mill is of high quality, fine and even. Trapezoidal mill is an advanced equipment in the flour milling industry. It has the international leading level in environmental protection and energy conservation, with less dust, no noise and stable operation.
Secondly, the pulverizer shall be crushed by a jaw crusher before grinding, and other grinding and rough grinding equipment can also be equipped until it is suitable for the grinding size of the mill. This can not only ensure the efficiency of the grinding process, but also ensure the powder quality of the finished product. Because the hardness of silica is high, excessive feeding will damage the pulverizer to a certain extent.
In addition, the whiteness of silica powder is very high, which is also the reason why it is widely used. Therefore, the requirements for whiteness are particularly high. Due to the material problem of Raymond mill, a small amount of iron powder will be produced more or less. For silica powder, which requires high whiteness and iron content, filiform iron powder is not allowed. Therefore, the general miner suggests that you can equip a set of magnetic separator for magnetic separation to remove the iron element in the powder, In this way, the quality of silica powder can be guaranteed.
Finally, the grinding of silica powder can be better determined according to different uses. Some Raymond mills can be used for grinding, while some require new type of grinding equipment MTW trapezoidal mills. Some require particularly high fineness, and need to be equipped with MW micro powder mills or LUM ultra-fine vertical mills to achieve this. Select the grinding equipment, and then equip the corresponding crushing, conveying and feeding devices to complete the processing of the whole grinding production line.
Compared with general grinding equipment, the silica mill produced by SMMVIK Machinery has higher production efficiency, high quality of finished products, and very few needle and flake products. In addition, the silica mill produced by the company conforms to the development trend of modern industrial production systematization and large-scale, and has the advantages of strong completeness, especially suitable for large-scale production, which is a direction of the development of mining equipment. Moreover, the ultra-high degree of automation of the company's silica mill can basically realize unmanned operation, bringing you a more perfect production experience.
The vertical pulverizer is an ideal equipment for preparing silica powder. SMMVIK Machinery is a manufacturer of industrial pulverizing equipment. The vertical pulverizer produced by SMMVIK Machinery has a wide range of uses, and can be widely used in metallurgy, power, cement preparation, waste gas desulfurization, waste slag treatment and non-metallic ore powder grinding. It is a good choice for preparing silica powder.
