The catalog of quartz sand deep processing products includes the production of photovoltaic (ultra-clear) glass sand, silicon micropowder, plate sand (powder), foundry sand (including 3D printing sand, coated sand), petroleum fracturing sand and other higher-grade quartz sand concentrates And downstream silica sand products. These quartz sand deep processing products are inseparable from the help of quartz sand deep processing equipment. As a manufacturer of quartz sand deep processing equipment, Guilin Hongcheng will introduce to you the advantages of quartz sand vertical grinding mill as quartz sand deep processing equipment today.
Quartz sand is a hard, wear-resistant, and chemically stable silicate mineral. Its main mineral component is SiO2. The color of quartz sand is milky white, or colorless and translucent. Shaped fracture, grease luster, and its chemical, thermal and mechanical properties have obvious anisotropy. After the quartz sand mined from the mine is processed, the product with a fineness of more than 120 mesh (less than 120 mesh) is called quartz sand, and the product with a fineness of more than 120 mesh is called silica powder. High-quality quartz sand deep-processing products are widely used as a basic industrial raw material in glass, glass fiber, ceramics and refractory materials, metallurgy, construction, chemical industry, casting, abrasive materials, electronics, optical fiber and other industries.
Turning quartz sand into high-quality quartz powder is a difficult deep-processing process of quartz sand. Currently, the main quartz sand deep-processing equipment for grinding quartz is Raymond mill and rod mill. Grinding with Raymond mill has low efficiency and high energy consumption. When using a rod mill, the above parameters are not as good as Raymond mill, and the product particle size cannot be controlled. Another problem is: as the fineness of micropowder increases, the iron content also increases, especially because of the invalid collision between the wear-resistant materials in the rod mill, the iron content is extremely high. In this case, it is difficult to remove the mechanical iron in it. How to greatly increase the production capacity of quartz micropowder mill while reducing the iron content, saving energy and reducing consumption is a technical problem that must be solved in large-scale production in this industry. In response to the above problems, the HLM type quartz sand vertical mill developed by Guilin Hongcheng provides help for reducing energy consumption per unit of product for grinding a large number of quartz. So, what are the advantages of quartz sand vertical mill as quartz sand deep processing equipment?

HLM quartz sand vertical mill is a high-efficiency energy-saving equipment for drying and grinding developed by Guilin Hongcheng. It not only has the advantage of Loesche mill that can be turned over for maintenance, but also has the characteristics of MPS roller sleeve that can be turned over for use and has a long service life. Integrating fine crushing, drying, grinding, powder selection, and conveying, it has high grinding efficiency, low power consumption, large drying capacity, easy adjustment of product fineness, simple process, small footprint, low noise, and no Dust pollution, low wear, convenient maintenance, reliable operation and other advantages. The grinding roller of the quartz sand vertical mill adopts a tire type, and the grinding plate liner adopts a bowl shape. On the one hand, it is to avoid the edge wear effect of the working surface of the grinding roller, and can be turned over for reuse, prolonging the service life. The surface tends to be steep, and the structure of a drum roller and a bowl is used to exhaust itself, and the principle of single roller self-preparing material bed is realized to control the material bed and reduce vibration. On the inside of the grinding roller, the gap between the roller discs is large, forming a material bed preparation area, the material bed is loose, and on the outside of the grinding roller, the gap between the roller discs is small, and the material bed is further dense, forming an efficient grinding area. In the whole grinding process, even if the specific surface area of the finished product is large, it can also achieve weak magnetism. On the contrary, the high-chromium cast iron mixed in the quartz powder is easily attracted by the magnet due to wear, so even if there is a small amount of mechanical iron in the powder It is easy to remove. According to the process control, our quartz sand vertical mill can control the mechanical iron pollution within 30ppm.
Compared with traditional quartz sand deep processing equipment, hlm vertical grinding mill has greatly improved stand-alone production capacity, which meets the needs of large-scale industrial production in the quartz sand deep processing industry. At the same time, the energy consumption and equipment consumption per unit of product are reduced by more than 40% compared with the Raymond mill grinding system. Quartz sand vertical mill has good adaptability for grinding high hardness and high fineness quartz powder. It is believed that it will surely drive other types of non-metallic mineral production enterprises to rapidly increase their enterprise scale and achieve low-carbon emissions.
