Worm feeders of WF-type
Are designed for handling bulk products (with bulk density from 0,4 to 4,5 t/min) to weight batcher, mixing machines and other devices.
Are transporters where loads move by dragging on fixed chute (pipe) with swiveling rotor blades.
Worm feeder consists of a chute, a screw auger with lead-in and transporting parts and a head section. Feeder’s drive is carried out with the help of electric motor and worm reducer (or geared motor). Feeder’s lead-in part is equipped with variable vanes (with variable pitch). Auger’s transporting part is built as closed screwed surface with 120, 200, 250, 400 mm pitch. Diameter of a pipe or a chute can vary between 89 and 1000 mm.
Worm feeders of more than 8m in length are constructed out of a number of transporting sections. The feeders can be produced with right and left (upper/lower) wire section layout with relation to the auger axis.
