connect to the discharge from it. Drawings are not however considered design drawings for the concept of a process or system. There are several kinds of screw conveyor product lines discussed in this manual. 1. Screw Conveyors 2. Screw Feeders 3. Screw-Lifts The instruction for erecting any of these screw conveyors is generally the same.
Two types of troughs are typically used with inclined screw conveyors: U-trough and tubular housing. The U-trough design is simple, economical, and provides access for maintenance. U-troughs are used in most horizontal screw conveyor applications and inclined applications up to about 20 degrees.

Insert coupling shaft into opposite end of screw and install coupling bolts. DO NOT TIGHTEN. COUPLING BOLTS. Pull screw section away from drive or thrust unit to seat thrust connection. Insert hanger onto coupling shaft. Raise hanger and screw section until hanger top bar is flush with top of trough.
A standard Screw Conveyor inclined 15° upward will carry 75% of its rated horizontal capacity. At an inclination of 25°, a standard conveyor may only handle 50% of its horizontal capacity. These are estimated figures and will vary with the characteristic of the material being handled. Inclined Screw Conveyor capacities can be increased over ...
Screw feeders are designed to operate under flooded conditions with a head load of product on the screw or multiple screws. The unit must be designed to overcome the static condition of the screws and the force exerted by the product head load. The product head load exerts a downward force on the screws and creates frictional resistance.
For screw conveyor design purposes, conveyed materials are classified in accordance with the code system shown in Table A. This system conforms to that of the Conveyor Equipment Manufacturers Association (CEMA) which ranks each material in 5 categories. Table B lists the codes for many materials that can be effectively conveyed by a screw …
