Sieves Are Kept Clean

Rotating Drum Sieving Machines

07.05.2015 Sieving machines are often used to sort bulk goods for size. Unfortunately, the pores of these sieves are easily obstructed or blocked by build-up of material.  Brace has therefore developed rotating drum sieving machines whose pores are kept clean by a brush located outside the sieving drum.

The rotating drum sieving machine can sort large amounts of bulk goods with very low consumption of energy. The rotating drum sieve machine works in principle like this: The bulk material is delivered to the first sieving drum via a vibrating channel. The particles whose diameters are smaller than the width of the mesh size can pass through and are separated from the rest. The larger particles travel to a second sieving drum whose mesh size is bigger than those of the first sieve, and so on. The particles that are larger than the mesh size of the last sieve are collected separately as oversized granules. Usually, two up to four different sieving drums are used for the fractionation of bulk goods. The use of a sieving drum is recommended for the sorting of volumes from 30-50 litres per hour upwards. For the sorting of very sensitive goods or of goods that are easily electrostatically charged when handled, the manufacturer offers drum sieving machines that are optimized for these purposes and can even sort wet goods.
