Vibrosieve

The Vibrosieve is a circular unitised gyratory screen. It is the largest of its type available today, with three-component multiplane mechanical vibration.

The motivation is through a motor with a double extended shaft, fitted at both ends with eccentric weights. The whole drive assembly is mounted on a circular base by rugged springs which allow the unit to vibrate freely, and at the same time, the springs prevent transmitted vibration reaching the floor area on which the machine stands. Vibrosieves can be mounted one on top of the other within the screening assembly. The Vibrosieve is suitable for all types of screening operations within these four broad categories:

Dry Separation
Division of different materials on the basis of their particle shape.

Dry Classification
Division of materials into precise sized fractions.

Solid-Liquid-Separation
Dewatering of solids and clarification of liquids.

Solids Classification
Separation of sized fractions in a liquid medium. Highest screening efficiency is achieved by controlling the patterns of movement of solids on the screen surface. Control is achieved by varying the position of the bottom eccentric weight as shown in the diagram.
