High Quality Silicon Metal Powder
What Properties Does Silicon Powder 325M for Thermal Spray Have?
1. High temperature resistance
Metal silicon powder has strong high temperature resistance, so adding an appropriate amount of metal silicon powder multiple times in the production of refractory materials and powder metallurgy can greatly improve the high temperature resistance.
2. Wear resistance
Usually we add metallic silicon powder in the production of some wear-resistant castings to improve the wear-resistant performance of the castings.
3. Deoxygenation
Metal silicon powder, as the name suggests, contains a certain amount of silicon, which can have an affinity with oxygen to generate silicon dioxide, which reduces the smelting reactivity during deoxidation and ensures the safety performance of deoxidation!

What Is The Production Process Of Metal Silicon Powder?
The production process of metal silicon powder: ① Bagged silicon blocks → Lifting and unloading by crane or forklift → Jaw crusher → Bucket elevator → ≤15mm silicon block silo → Electromagnetic vibrating feeder → Grinding mill → Cyclone Separator → Powder collection bin → Screening machine (vibrating screen) → Finished silicon powder → Bag filter → Dust collection tank → Exhaust gas exhaust fan. ② Silicon block → Crushing → Belt → Bucket lift → Pulverizer → Gas-solid separation → Screening → Empty the finished product warehouse ← Exhaust fan ← Bag filter ← Blower ← → Coarse powder is returned to the mill ↑ Enter N2 → Fine powder recovery ③ Raw materials Silicon block bin → Belt weighing → Primary crushing → Screening (rotary vibrating screen) → Secondary crushing and rotary crushing ← Electromagnetic vibration of feeder ← Bucket lifting → Screening → Coarse powder return to bucket and medium powder storage → Secondary Screening→Fine powder bin→Bag filter→Exhaust fan→Tail gas venting to package fine powder.
Silicon Nitride Powder 325m
In the entire production process of metal silicon powder, ultrasonic vibrating screens are manufactured according to process conditions and technical requirements. Ultrasonic technology is used in the material screening process. The high-frequency electrical oscillation generated by the oscillator is converted into sinusoidal and longitudinal oscillations by the converter. These fluctuations are transmitted to the pre-adjusted rod resonator and then evenly transmitted to the screen surface. So as to achieve the effect of thorough screening.
