Screw Conveyor Engineering Guide

The KWS Screw Conveyor Engineering Guide will provide assistance in the design of a screw conveyor or system, yielding optimum performance and efficiency.

Screw Conveyor Engineering Guide – Index

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. Required distance and incline the bulk material is to be conveyed
  4. Design conditions such as materials of construction, inlet feed conditions and operating temperature

The Engineering Guide provides the necessary information for selecting a screw conveyor in a series of five steps. These steps are arranged in logical order and are divided into separate sections for simplicity.

The five steps are:

  1. Establish characteristics of the bulk material to be conveyed.
  2. Determine conveyor size and speed based on capacity.
  3. Calculate horsepower requirements.
  4. Verify torque rating of components.
  5. Select conveyor components.
