Screw Conveyor is a general type conveyor. Its mainly used for conveying granule, powder and compound material. Two models as your choice Horizontal Screw Conveyor and Inclined Screw Conveyor. According to customers different requirements and industry, we can do special design for
screw conveyor is affected by its diameter, intake length, angle of elevation, speed, and moisture content of grain. The length of a screw conveyor will affect power but not capacity. They also indicated that power requirements increase with angle of elevation to 45, then decrease as the angle goes to 90 and that as angle of elevation increases
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.
The driving power ...
Jan 05, 2007 Dir Sir, I want to kown how to calculate power for a screw conveyor. Could you give me a formula for it? If my parameter is screw pitch is 400mm, diameter of the screw blade is 400mm,the srew rotary revolution is 40 rpm.the capacity of the device is 25 cube meter per hour, degree of filling is 50% and the inclination angle is 3 degree. is there parameter enough?Could you give the formula to ...
requirements for inclined screw conveyors increase with the degree of incline .

TSHP 0.256 1.320 1.576 H.P. Assuming a drive efficiency of 85% resulting in a total drive horsepower of 1.853, a standard 2 horsepower motor would be selected for the drive input. The horsepower required for the above conveyor may also be determined graphically by the use of the two horsepower nomographs.
