best conveyor design. Since the Screw Conveyor selected is based on a maximum volume control of material to be handled, surge loads, overloads and choke feeding must be accounted for in the conveyor design. Screw feeders are popularly used for this control and are discussed in other pages of this catalog. CLASSIFY YOUR MATERIAL

A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a "flighting", usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline

Table B lists the codes for many materials that can be effectively conveyed by a screw …

Primary considerations for the selection of a screw conveyor are: 1. Type and condition of the bulk material to be conveyed including maximum particle size and specific bulk density 2. Capacity or feed rate of bulk material to be conveyed expressed in pounds per hour, tons per hour, or cubic feet per hour 3.

The purpose of a screw conveyor is to transfer product from one point to the next. Screw conveyors are always control fed at the inlet by another conveyor or metering device. Rotary valves, screw feeders, belt conveyors, grinders, or even other screw conveyors typically are connected to the inlet of a screw conveyor.

force on the screws and creates frictional resistance. As a result, additional torque is required to start and operate a screw feeder when compared to a screw conveyor. Special consideration is required when designing screw feeders. The starting torque requirements of screw feeders can be as much as 2-1/2 times the demand running torque.

Insert a coupling shaft into the next screw section and secure tightly with coupling bolts. Place screw in trough so that there is approximately 180° between lighting ends of mating screw sections. Slide screw section over the end of coupling shaft of the previous screw section. Secure tightly with coupling bolts. 9.
