The industrial screener type DF is a high performance-screening machine for medium and coarse separation range

The drive principle of the DF type industrial screeners is based on the use of two out-of-balance motors running with different speeds. The motor with the lower speed and higher out of balance weight is positioned at the inlet, whereas the motor with the higher speed and lower out of balance weight is positioned at the outlet.

At the inlet part, the higher amplitude accomplishes loosening and mixing of the feed product. At the outlet part, the high motor frequency along with higher accelerations ensures that critical materials are screened. By changing the direction of rotation the transport speed of the product can be specifically influenced. Due to this driving principle nearly no vibrations will be carried into the building.

A static machine case encloses the vibrating screening unit and enables fixed flange connections as well as a dust-tight screening process (FDA, ATEX).

The easy machine accessibility and the maintenance free drive by two out of balance motors minimize the service costs and shut-down periods. The out of balance drives positioned outside the screening aggregate allow to operate on high product temperatures (max. 450° C!).

The vibrating screening unit is encapsulated by a static housing allowing rigid connection of on- and off-going chutework.

Standard industrial screener sizes are in the range of 3.0 m² to 72 m² per screen deck resp. machine. Additional sizes and special constructions are possible on demand. Electrical power consumption of these machine sizes usually is within 2.5 kW and 19.0 kW (!)
