Rubber sieve balls are made of natural rubber (NR), silicone (MQ), nitrile (NBR), EPDM and styrene-butadiene rubber (SBR) in three dimensions with a diameter of 30 mm, 37 mm and 47 mm. The main application of the balls is to clean the sieves from the contaminants deposited in the sieving process. Depending on the rubber base, the balls have different physicochemical parameters.
EPDM balls – minimum order quantity 500 pcs.
