HAVER-Test Sieve Shakers produce a three-dimensional sieving action. The material is distributed over the whole sieving surface. For difficult products, sudden interruption of the sieving action using intermittent drives intensifies the sieving and in many cases reduces the sieving period.
HAVER Test Sieve Shakers have no rotating parts, are extremely durable, maintenance free, very adaptable and have a low noise level. Due to the use of a special spring system and cast iron parts, the construction is heavy and sturdy. This avoids unwanted vibrations being transmitted to the stationary parts of the sieve shaker and its stand.
