Double tube screw feeder
This spiral feeder is suitable for uniform and continuous feeding of dry powder materials such as coal powder, cement, grains, sand and so on. This equipment adopts a cycloidal pinwheel reducer and is equipped with a VF frequency converter, which has a wide speed range, stable operation, low noise, compact structure, and small volume. It can easily adjust the material flow and meet the requirements of different production processes.

Q=2*60π/4(D2-d2)(S-δ)nФ
In the formulation:
Q-feeding capacity of double tube spiral feeder (m3/h) δ- Spiral blade thickness (m)
D - Spiral blade diameter (m) n - Spiral speed (r/min)
d-Spiral rod diameter (m) Ф— the filling coefficient of the material (generally=0.9)
S - Pitch of the helix (m)
