It also calculates the voltage drop and maximum distances of the feeders.
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 … The "Screw Conveyor Design Procedure" on the following page gives ten step-by-step instructions for properly designing a screw conveyor. These steps, plus the many following tables and formulas throughout the engineering section will enable you to design and detail screw conveyors for most applications.
Example. A 10-inch conveyor 35 feet long with a capacity of 10 tons per hour at 45 RPM has been selected. From the Materials Table, a Horsepower Factor of 0.8 is found for the material to be conveyed. Under static equilibrium conditions, the screw rotates at a constant speed in response to the input torque T shown in the free-body diagram above. In addition, the load force F, normal force N, and sliding friction force Ff act on the power screw. tive motion.
