Screening

Screening

Sifting - Classifying:
Materials are usually sifted in line with grinding to control the upper or lower limit of the specified particle size. Sifting or screening to 1/2" down to 200 mesh or 12.5 mm to 75 microns is offered as a standalone service to separate oversize or undersize from powdered materials. Multiple-cut classifying is offered to separate powders into cuts or fractions of different specific particle size distribution ranges. Cryogenic screening can be done when needed for sticky or tacky materials.
