Conveyors design

Power. The power requited to drive a belt conveyor is derived from the tensile forces requited to propel or restrain the belt at the design speed. These include the tensile forces produced by the frictional resistance of the drive, conveyor components, and material the acceleration of the material and the gravitational forces requited to lift or lower the material. Detailed information and methods of calculation can be found in belt conveyor design handbooks and in Reference 9. 

Linear transport velocity of the material is almost proportional to the product of frequency and stroke for these conveyors. However, the transport velocity and the depth that can be obtained with a specific material is dependent on the handling characteristics of that material. Manufacturers have accumulated data banks relating material characteristics to attainable conveying velocities for their proprietary conveyor designs. 

Nomographs for Preliminary Design A useful set of nomographs for determining conveyor-design parameters is given in Fig. 21-13. With these charts, conservative approximations of conveyor... 

Belt-conveyor designs use both roller and shder bed supports for the flat belt. The variety of designs available aUows proper selection of flat belts for heavy or hght loads and for various applications such as carton filling or emptying.

Particle size. The material handling properties of solid wastes are dependent upon particle size. This appfies as well to feed preparation and air pollution control which are affected by solid-waste particle size and cohesiveness. For wastes such as bulk soils, the amount of fines (from clay and silt) is critical for system design. Cohesiveness, which varies with moisture content, is important for Din and conveyor design.
