HAVER EML : Test Sieve Shakers

As well as high-quality test sieves, an efficient overall concept also includes modern test sieve shakers. HAVER & BOECKER provides a multitude of systems for widely differing applications. HAVER Test Sieve Shakers generate a three-dimensional sieving action for fast and optimally reproducible sieving results. The product is accelerated vertically out of the mesh and at the same time fed over the surface of the sieve in a circular motion. This 3D process saves time and manual re-sieving.
HAVER & BOECKER also uses G-Control in all electromagnetically operated test sieve shakers (HAVER EML). G-Control is an automatic amplitude control system which continuously measures the acceleration of the whole sieve tower. This fully compensates for all natural oscillations of the sieving machine and the subsurface so a constant amplitude is guaranteed at all times, regardless of feed rate.
