How to produce silicon powder
Silicon powder deep processing uses physical methods to process and purify industrial silicon powder. This technology uses ordinary industrial silicon as the production material, which is processed through physical methods and controlled by an automated operating system. It achieves the goal of improving the grade, eliminating impurities, maintaining the hardness of the silicon crystal, and producing quasi-high purity silicon powder without changing the structure. Silicon powder production process: After cleaning qualified industrial silicon with purified water, it is crushed into small particles. After primary electromagnetic selection, it is sent to the first and second stages of Raymond grinding and ultra-Raymond grinding to 200 to 400 mesh. An appropriate amount of purified water is added during the grinding process, and the ground silicon liquid flows into a sedimentation tank for liquid phase deposition. Then, a catalyst with an acid value of 6 is added and stirred for 2 to 3 hours to separate impurities in the silicon liquid; after drying, it is subjected to air crushing for electromagnetic separation and screening and finally enters vacuum packaging through a cyclone collection device. The silicon powder production equipment comprises a cleaning device, primary magnetic separation, grinding system, sedimentation system, drying system, magnetic separation, and cyclone collection system. Auxiliary facilities include a power supply system and a water purification system. The central machinery of silicon powder production equipment includes: Raymond mill, sedimentation system, magnetic separation, cyclone collector, recovery system, wind crusher, purified water device, axial flow saw; Electrical equipment includes transformers, high-voltage cabinets, low-voltage control systems, and power distribution; Environmentally friendly dust removal equipment.
