Task of the machine: to eliminate the foreign materials, impurities of a dimension superior or inferior to that of the material to be purified.

Two vibromotors move the screen box and the inflow case built onto it.

In the multi-purpose machine, the screening angle of slope the position and counterweights of the vibromotor are adjustable.

Vibrational motion helps to a great extent the self-classification of the material passing through the coating and precise work of the machine.

The machine is adequate for the cleaning of various granulous materials (maize, coffee, cocoa bean, etc.) as a milling or silo cleaning machine, and also for the purifying of sowing seeds. A suction or wind-cleaning box can be connected to the outflow.

Other than the vibromotor, it contains no moving part, thus requires no special maintenance.
