Silicon Metal Powder Screening Machine Solutions Introduction

Silicon metal powder screening machine, also known as industrial silicon powder classifier or silicon material screening equipment, is the core equipment in the metal silicon processing process, mainly used for fine classification and screening of metal silicon powder. The metal silicon powder screening machine has the advantages of strong processing capacity, high screening accuracy, excellent sealing performance, low operating noise, etc. It can improve the production efficiency of metal silicon powder and the quality of products, and meet the strict requirements of metal silicon powder particle size in different application fields.

Material analysis

Metallic silicon, also known as crystalline silicon or industrial silicon, is an important non-ferrous alloy additive. Silicon is a non-metallic element with a gray appearance, hard and brittle texture, high purity, good conductivity and thermal stability. Its particle size distribution ranges from fine powder to larger particles, with a certain specific surface area and surface activity. During the screening process, it is necessary to pay attention to the electrostatic effect of metallic silicon powder and adhere to the surface of the screen, affecting the screening efficiency.

The derivative products of metallic silicon include silicon micropowder (also known as silicon powder, micro silicon powder or silicon ash), silicon edge skin, black silicon and metallic silicon slag. In the production process of metallic silicon, the powder needs to go through a pretreatment stage, such as crushing and grinding. In this process, the metal silicon screening machine is mainly used for fine particle size classification.

Application

Metallic silicon (or industrial silicon) is an important industrial raw material, mainly used in the following aspects:

Manufacturing high-purity semiconductors: Metallic silicon is a key raw material for manufacturing high-purity semiconductor materials, and can be used to manufacture solar cells, high-power transistors, rectifiers and other electronic devices.
Important raw materials for organosilicon compounds: Organosilicon compounds have the advantages of high-temperature resistance, low-temperature resistance, oxidation resistance, ozone resistance, radiation resistance and electrical insulation, and can be used in construction, electronics and electrical, textiles, automobiles, machinery, leather and papermaking, chemical and light industry, metals and paint coatings, medicine and medical treatment and other industries.
Alloy preparation: For example, silicon aluminum alloy is a strong composite deoxidizer, which can improve the utilization rate of deoxidizers, purify molten steel and improve the quality of steel in the steelmaking process. Silicon aluminum alloy has the advantages of low density, low thermal expansion coefficient, good casting performance and wear resistance, and is used in high-end manufacturing fields such as aerospace vehicles and automotive parts. Silicon copper alloy has good welding performance and explosion-proof function, and is used to make safety equipment such as storage tanks.
Building materials: Metallic silicon can also be used to make building materials such as glass, concrete, bricks, and refractory materials.
