The advantages of special production line of metal silicon powder processing enterprises
At present, domestic metal silicon powder processing enterprises have their own processing metal silicon powder special production line, safe, environmental protection, low loss, effective! The configuration of the production line can be carefully designed according to the site investigation or the actual requirements of customers, which fully reflects the rationality, effectiveness, applicability, high output, low wear, low operating cost and environmental protection.
Silicon metal is a hard and brittle material. In the grinding process, fine powder is difficult to effectively control, the powder phenomenon is serious, resulting in a large waste of products, high production costs, particle size is not qualified, the product lacks competitiveness. For many years, the problem of silicon metal crushing has been troubling the processing enterprises of silicon metal powder.
After years of research and development and experiments, the domestic metal silicon powder processing enterprises according to the physical properties of metal silicon, successfully developed and produced a special production line for processing metal silicon powder, the market application of the production line has won the industry insiders and experts alike high praise.
Silicon powder processing refers to the process of smashing the smelted silicon blocks through a special process to produce silicon powder with a specific size range. In the past ten years, with the rapid development of silicone and polycrystalline silicon industry, the processing technology and equipment of metal silicon powder processing enterprises have become increasingly mature, from the original open crushing to the present closed, continuous, highly automated processing and production process.
At present, the main technology of silicon powder processing is roller grinding and punching and spinning. The main equipment is as follows: Roller mill and impact rotator are different in the grinding process to meet the quality and technical requirements. The former is ground into powder under gravity extrusion, while the latter is crushed by impact. Various mills can process and crush minerals with a Mohs hardness of 7.0 to 8.0. But in contrast, the roller mill has the advantages of small volume, simple structure, convenient maintenance, the control of fine powder rate is far higher than the punch.
The advantages of special production line for metal silicon powder processing enterprises:
1. The production line adopts unique structure design, and the material is crushed instantaneously. After the material is crushed once, the particles that meet the requirements of particle size are separated quickly without the need of two crushing, which effectively avoids the excessive crushing of material particles and greatly reduces the powder yield of fine powder.
2, production line with screening machine is a special screening machine designed for silicon metal powder after comprehensive testing and improvement of domestic screening equipment. The screening machine can not only greatly improve the screening efficiency, but also prolong the service life of the screen.
3. Equipment wear and maintenance rate The main mill of the production line is designed with a strong wear-resisting device, which greatly prolongs the service life of the mill. The equipment can run stably for a long time and the product quality is stable.
4. Particle morphology difference The product size distribution of the production line is uniform and normal. The surface of the product is polygon according to the electron microscope, and the specific surface area is large.
