Single and double screen PWP type vibration screens are destined for classification of aggregates and other loosematerials in dry and wet processes and for dewatering, elutriation, flushing, etc. The screens are equipped with inertia drives f1xed mounted in the screen sides, joined directly with electric motors.
Contra rotating unbalanced masses of drives cause centrifugal forces, which either delete themselves or sum up in certain positions, thus initiating harmonie movement with elliptical trajectory of the springy supported screen. Movement parameters and kinds of screens are selected depending on process requirements.
Depending on requirements of the ordering party the screen construction may be connected with strengthened bolts or the HUCK-BOLT type joints.
There is a possibility of constructing the screen according to special technical requirements of a customer.
