Grain separator | RHEWUM DFM

Grain separators for various and specific grain sizes

The DFM double frequency screening machines are high performance grain separators for the medium and coarse separation range. The drive principle of the DF type machine is based on the use of two out-of-balance motors running at 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 the loosening and mixing of the feed product. At the outlet part, the high motor frequency along with higher acceleration 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 almost, no vibrations will be carried into the surrounding structure.

Flexible sealing sleeves in the inlet and outlet ensure dust-free operation (FDA, ATEX).

The easy machine accessibility and the maintenance free drive motors minimize the service costs and shut-down periods.

Standard machine sizes are in the range of 3.0 m² to 36 m² (32.3 ft² to 387.5 ft²) per screen deck with up to five screen decks per machine. Additional grain separator sizes and custom designs are available on demand. Electrical power consumption of these machine sizes is usually within 4.0 kW and 16.5 kW (5.4 hp and 22.4 hp) (!).
