Multi-deck plansifters are designed for a wide range of sharp separations in the medium to fine particle range from 20 μm (635 Me.). The material is transported using the microthrow principle.
By using the drive of two counter-rotating unbalance motors, which generate a linear vibration, the particles are subjected to a large number of individual throws until they leave the machine. The screening material moves in a linear motion over the horizontal separating surface. In this process, the screening machine operates with low vibration acceleration and thus with very low wear on both screen cloths and machine components.
