How to conduct an iron powder screening test?

Introduction to Iron Powder
Aggregates of iron particles with a size less than 1mm. Color: Black. It is the main raw material for powder metallurgy. According to particle size, it is customarily divided into five levels: coarse powder, medium powder, fine powder, ultrafine powder, and ultrafine powder. Particle size ranging from 150 to 500 μ The iron powder composed of particles within the range of m is coarse powder, with a particle size ranging from 44 to 150 μ M is medium powder, ranging from 10 to 44 μ M is fine powder, 0.5-10 μ M is extremely fine powder, less than 0.5 μ M is ultrafine powder. Generally, it will be able to pass the 325 target sieve with a particle size less than 44 μ The powder of m is called sub sieve powder. To achieve higher precision screening, air flow classification equipment can only be used. However, for some easily oxidized iron powder, JZDF nitrogen protection classifier can only be used. Iron powder mainly includes reduced iron powder, atomized iron powder, and cast iron powder; They are named after different production methods.
Application of Iron Powder
An important metal powder in the powder metallurgy industry. Iron powder is widely used in powder metallurgy production, accounting for approximately 85% of the total consumption of metal powder. The main market for iron powder is the manufacturing of mechanical parts, and the required amount of iron powder accounts for approximately 80% of the total production of iron powder.
Classification of iron powder
Iron powder screening can generally use a rotary vibrating screen for coarse screening, but high-precision classification requires an ultrasonic vibrating screen. For iron powder classification that is prone to oxidation and explosion, only nitrogen protection classifier and airtight ultrasonic vibrating screen can be used for high-precision classification.
