A 16-inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80-rpm. The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm
Feb 20, 2018· Screw Feeder Capacity and Speed The pitch of the last screw flight going into the shroud determines the feed rate of the screw feeder and is called the control pitch. The control pitch is typically less than full pitch. The capacity of the control pitch is calculated in cu ft/hr per RPM.
The key to proper screw feeder design is to provide an increase in capacity in the feed direction [4]. This is particularly important when the screw is used under a hopper with an elongated outlet. One common way to accomplish this is by using a design as shown in Fig. 1.

Jan 01, 2016· A mass flow screw feeder, comprised of a tapered section followed by a section with increasing pitch, ensures that the capacity of the feeder increases in the direction of flow (see Figure 13). The length of the cone and the pitch schedule are chosen such that the capacity of the screw increases linearly along the hopper length.
