When the exact weight of the belt is not known, use average estimated belt weight (see Table 6-1) W m =weight of material, lbs per foot of belt length: Three multiplying factors, K t, K x, and K y, are used in calculations of three of the components of the effective belt tension, T
BELT CONVEYORS FOR BULK MATERIALS 1. INTRODUCTION: Belt conveyors consist of two powered pulleys with a continuous loop of belting material used to convey products. Belt conveyors are the most economical powered conveyor and are typically used for conveying products over long distances, at high speeds, or for incline/decline applications.

The belt conveyor consists of belt, drive and end pulleys, idlers and tension mechanism, loading and discharge devices. Its carrying capacity depends on the width of belt, angle of trough, and belt speed. Belt conveyors have a high mechanical efficiency because the load is carried on anti-friction bearings.
Screw conveyors are also more economical alternatives to a belt, pneumatic, or aeromechanical conveying device. Using multiple inlets and discharge points, screw conveyors efficiently distribute bulk materials to different areas. Plus, screw conveyor systems are able to contain corrosive or hazardous materials. Keeping Business …

Primary considerations for the selection of a screw conveyor are: Type and condition of the bulk material to be conveyed including maximum particle size and specific bulk density. Capacity or feed rate of bulk material to be conveyed expressed in pounds per hour, tons per hour, or cubic feet per hour. Required distance and incline the bulk ...
force on the screws and creates frictional resistance. As a result, additional torque is required to start and operate a screw feeder when compared to a screw conveyor. Special consideration is required when designing screw feeders. The starting torque requirements of screw feeders can be as much as 2-1/2 times the demand running torque.
