Screw Conveyors are one of the oldest and simplest methods for moving bulk materials and consist primarily of a conveyor screw rotating in a stationary trough. Material placed in the trough is moved along its length by rotation of the screw which is supported by hanger bearings, inlets, outlets and other accessories controlling the material and its disposition.
DESIGN AND SIZING OF SCREW FEEDERS By Marco Bortolamasi Johannes Fottner Abstract This paper is concerned with the design criteria of screw feeders: a non proper design and selection of this device, which is present in large part of industrial processes, could .
Screw Conveyors are versatile and can be employed in horizontal, inclined and vertical installations as well as multiple screw Live Bottom Feeders. Screw Conveyors can be sealed for dust free and vapor tight requirements. A Screw Conveyor can be used for heating and cooling products by utilizing jacketed housings and/or hollow flight screws.
Shafted screw conveyors are compact and easily adapted to congested layouts. Custom Conveyor's Shafted Screw Conveyors efficiently convey dry to semifluid and freeflowing to sluggish materials. Screw conveyors are available in a wide variety of materials and US Conveyor Equipment Manufacturers Association (CEMA) sizes.
Inclined Screw Conveyors Inclined screw conveyors typically operate from slightly above the horizontal position to 45 degrees from the horizontal position. Above 45 degrees an inclined screw conveyor is considered a vertical screw conveyor and must be designed in accordance with the CEMA guidelines for vertical screw conveyors.
The NBE line of applicationspecific flexible screw conveyors and hoppers is built to ensure power, performance, and longevity in harsh applications, in demanding environments, and in extreme duty cycles.

What Is a Screw Conveyor? Screw conveyors, also known as worm conveyors or spiral conveyors, transport material over a flat or inclined plane. A screw conveyor moves a regulated volume of material from the inlet point to an outlet point. Material at the inlet is regulated based on the size and horsepower of the conveyor.
