choosing a screw conveyor system for your tough material articleto handle a toxic material, choose a screw conveyor with a vaporand dusttight housing. the conveyor should have extremely tight shaft seals, such as gaspurged seals or flangetype gland seals with multiple rings of packing material. also use a dust control system that captures and removes toxic fumes and dust at the conveyor discharge. engineering guide screw conveyors bulk material handlingscrew conveyors are typically designed to convey bulk materials at 15, 30 or 45percent trough loading, depending upon material characteristics of the specific bulk material. as a general rule, trough loading of 45percent can be used for light, freeflowing and nonabrasive bulk materials. screw conveyors, screw conveyor components ampauger screw screw conveyors are designed for bulk material handling in industrial and agricultural applications with the use of rotating helical screw blades also known as augers. they can be utilized in vertical and horizontal configurations to move anything from solids to liquids. screw conveyors, screw conveyor components ampauger screw standard screw conveyor a typical screw conveyor consists of a trough, screw (auger), trough cover, discharge spouts, coupling and end shafts, bearings, hangers, and associated hardware. their sole purpose is to transfer material from one point to the next, these can be used in 0° to 45° incline applications. screw conveyor design calculation an engineering guidea typical screw conveyor design is shown below : figure 1 : screw conveyor principle drawing and key components. 2. design procedure of a screw conveyor how to calculate the size and capacity of a screw feeder ? known : capacity required of the screw conveyor, material unknown : screw size and characteristics. 2.1 general formula screw conveyors ampfeeders wamgroup wam incscrew conveyors ampfeeders as the worldwide leading manufacturer of screw conveyors and screw feeders, with more than half a million units supplied in four decades, wamgroup offers screw conveyors and feeders tailored for specific purposes and a variety of industries. screw conveyor capacity engineering guidea larger screw conveyor diameter will be required for lower screw conveyor speeds. maximum lump size must also be considered when designing a screw conveyor. please refer to the bulk material lump size section for further information. the capacity table is only intended for designing control fed screw conveyors.
