The BFC-SF20 screw feeder is a tubular or trough screw conveyor designed for controlled metered feeding of powders, granules and fine bulk materials. The 200 mm diameter screw rotates at low speed beneath a hopper to deliver consistent, volumetrically accurate flow. Variable pitch screws can be used to relieve hopper pressure and ensure uniform withdrawal. Fully enclosed design contains dust and prevents contamination. Ideal for cement, fly ash, lime, chemicals, food powders and other fine materials requiring dust-free controlled feeding.
