Screw Conveyor Engineering Guide
The engineering section of this catalog was compiled to aid you in the design of a conveyor system, yielding optimum performance and efficiency, for your individual conveying function.
Primary considerations for the selection of a screw conveyor are:
- Type and condition of the material to be handled, including maximum particle size, and, if available, the specific bulk density of the material to be conveyed.
- Quantity of transported material, expressed in pounds or tons per hour.
- The distance for which the material is to be conveyed.
In the next sections is the necessary information for the selection of a screw conveyor system, presented 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:
- Establishing the characteristics of the material to be conveyed.
- Locating conveyor capacity (conveyor size and speed) on capacity tables.
- Selection of conveyor components.
- Calculation of required horsepower.
- Checking of component torque capacities (including selection of shaft types and sizes).
All necessary calculations are expressed in graphic and equation form, and use of all charts, graphs, etc. will be explained fully at the end of each section.
Engineering data regarding the design of screw feeders and their selection, is presented in a separate section, immediately following the screw conveyor data.Any unusual applications, or special designs, should be referred to Kase Engineering Department.
