onstant torque from zero speed up to base motor speed. Determine the VFD Size. The VFD must be sized for at least 2 times the full-load amps o. the motor to allow for the high inrush of current during screw feeder starting. For example, a typi. al 20 hp premium eficient motor is rated for 49-amps at full-load and 230-vol.

Advantages of Using Vertical Screw Conveyors. Ideal for handling dry to semi-fluid materials from free-flowing to slighlty sluggish. Capacities available up to 6,000 cubic feet per hour. Ability to elevate bulk materials up to 30-feet without use of internal bearings. Totally enclosed design for dust and vapor-tight requirements.
The capacity calculation for screw conveyors takes into account the outside diameter of the screw, the outside diameter of the center pipe, the pitch of the screw and the trough loading. The calculation determines the capacity that will be conveyed with each revolution of screw rotation. Most CEMA approved screw conveyor manufac-

The authors of the article at hand merely found one recent publication (Karwat et al., 2021), where research findings from discrete element simulation of a screw conveyor were explicitly compared with results obtained from the Conveyor Equipment Manufacturers Association (CEMA) standard calculations.
The calculation determines the capacity in cubic feet per hour that will be handled with each revolution per minute of screw rotation. It is not necessary to memorize this calculation. Most CEMA approved screw conveyor manufacturers have the CEMA capacity calculation and guidelines as part of their screw conveyor design software.
