Particle size distribution of chromite sand afs45-50
chromite sand has an AFS (American Foundry Society) particle size distribution of 45-50, meaning its average particle size ranges from 0.320 mm to 0.270 mm. The specific distribution is as follows:
AFS 45: Average particle size is approximately 0.320 mm.
AFS 50: Average particle size is approximately 0.270 mm.
Particle size distribution range
AFS 45: The main particle size is between 0.355 mm and 0.250 mm.
AFS 50: The main particle size is between 0.300 mm and 0.212 mm.
application
Casting: used in molding sand to improve the surface quality of castings.
Refractory materials: used to make refractory bricks and castables.
Chemical industry: as raw material for chromium compounds.
Things to note
Granularity control: The appropriate AFS value needs to be selected according to specific needs.
Dispersion concentration: Dispersion will affect performance and needs to be strictly controlled.
Summarize
AFS 45-50 chromium ore is suitable for foundry, refractory materials, chemical industry and other fields.
