Sieving

Materials can be sieved from 10mm down to 75 microns. This can be used to remove oversize or undersize particles or to remove outsize contaminants. Sieving is frequently used as a final Critical Control Step in food processing.
Air swept sieves can be used to remove coarse particles or to sieve low density fine materials, they generally only provide two fractions oversize and undersize.
Oscillating and vibrating sieves can operate effectively down to 50 microns using ultrasonic cleaning. They offer the advantage of gentle action for friable materials and can provide more than one sieved fraction in one process step.
Custom Powders Ltd can offer more than 10 different sieving processes with oscillating sieves with brush or air jet cleaning, vibrating sieves with Ultrasonic or mechanical cleaning and a range of air swept sieves.
Process standards range from Industrial chemical, to food, to full GMP
