A. Indicated capacities are typical for normal materials, 0.7 gr./cm3 bulk density.

B. The low-capacity screw is sensitive to hard flowing material, or electrostatic charge, especially at high revolutions. Therefore, it is not recommended for use when a current of over 60% is required. Whenever possible, it is recommended that you use the medium-capacity screw and not the low-capacity one.

C. Maximum capacity is limited due to the size of the hopper and the filling rate of the venturi loader. With larger hopper (optional) equipped with a slide filling valve instead of the venturi loader, higher maximum capacities may be achieved: 25 kg/h for the High-capacity (3) screw, and 40 kg/h for the Extra-capacity (4) screw.

D. Extra-capacity screw is recommended for "hard" dispersing (flowing) materials.
