What is the steel ball milling process for industrial silicon powder processing equipment?

The silicon block is dried and crushed and then fed into the steel ball mill. The ground silicon powder is taken out by the circulating air flow and separated by the separator. The coarse particles return to the steel ball mill, and the fine particles are passed through the steel ball mill. The cyclone dust collector collects dust and enters the finished product warehouse. Most of the dust-containing gas coming out of the cyclone dust collector is circulated, and a small part of the dust-containing gas is dusted by a first-level bag and discharged to high altitude after first-level washing.

To sum up: vertical mills, Raymond mills and steel ball mills are all equipment for industrial silicon powder processing. Raymond mills and steel ball mills were earlier used to grind silicon powder. However, due to the complex process and low efficiency, silicon powder The product has finer particle size, difficult to adjust process parameters, high noise, and requires a soundproof cover; the consumption of grinding media rollers, steel balls, and lining plates is large; the silicon powder contains high iron content; grinding requires high oxygen content in the system, so it must be It is carried out under nitrogen protection and consumes a lot of nitrogen. Therefore, Raymond mills and steel ball mills are rarely used to grind silicon powder in newly built silicone plants. Vertical mills are widely used in cement, non-metallic, chemical and other industries. Compared with Raymond mill systems, vertical mills have the following advantages: a. Vertical mill systems have less equipment, simple processes, and good system sealing; b. The vertical mill system uses one-stage dust collection, which is highly efficient and easy to operate, while the Raymond mill uses three-stage dust collection, with a complex process system and low efficiency; c. The Raymond mill is a suspension roller mill, while the vertical mill is a pressure roller Grinding, safety is good; d. The vertical mill system has low noise, the actual measurement is 85 decibels, and no sound insulation cover is needed; e. The energy consumption per unit product of the vertical mill system is lower than that of the Raymond mill system.

As a manufacturer of industrial silicon powder processing equipment, we have a variety of industrial silicon powder equipment such as Raymond mill, vertical mill, and ring roller mill for customers to choose from. Among them, the vertical mill system has a simple process, easy operation, safety, and good dust collection effect. The particle size and particle composition of the silicon powder are more suitable. The system has a high degree of automation. The equipment noise and energy consumption per unit product are low, and the nitrogen consumption is far low. The Raymond mill system will become an advanced equipment for industrial silicon powder processing in the future.
