Screw Feeder Horsepower Requirements The horsepower and torque requirements for a screw feeder are much higher than a comparable screw conveyor. A screw feeder must start up with a flood loaded inlet and the head load weight of the bulk material in the inlet section. Bulk materials also tend to pack when under pressure in a hopper, bin or silo.
Horsepower is defined as the power required to safely and feasibly convey a bulk material a fixed distance in a screw conveyor. The horsepower required to drive a screw conveyor is called Total Shaft Horsepower, or TSHP. TSHP is a function of the characteristics of the bulk material being conveyed and the friction inherent in the screw conveyor.

Mar 04, 2006· There is no short cut for deciding the load torque. This cannot be calculated from motor side. 5) Having decided the load torque, you can decide the required power at motor shaft, available motor size, gear ratio and so on. 6) I will suggest you to take the help of conveyor designers, who may be also available in your country.

Two screw conveyors with diameters of 20 and 25 cm were evaluated at four screw clearances (6, 9,12 and 15 mm) and five screw rotational speeds (200, 300, 400,500 and 600 rpm).
for screw conveyors While a screw conveyor may be viewed as a simple mechanical device, grain operators rely heavily on this equipment to move dry bulk materials from one process to another. The mechanical power transmission equipment used on these conveyors is exposed to a wide range of tough operating conditions, including numerous

An auger conveyor (or screw conveyor) consists of a helicoid screw rotating within an enclosed tube or open U-tube (Fig. 3.7).Its invention is credited to Archimedes ( BC) who used it to pump water from the holds of ships (CEMA, 2003).With only one moving part in contact with grain, low-cost augers are simple and find extensive use especially in intermittent use conveying systems.

Screw Conveyors. Screw conveyors, also known as auger conveyors or industrial screw conveyors, are systems designed to transfer free-flowing and non-free-flowing, dry and semi-dry bulk materials.Note: Since the operation of the system involves a screw cutting through the bulk materials, we do not recommend using screw conveyors to process substances that are sticky or do not break down …
