It is important to understand, however, that as the angle of inclination increases, the allowable capacity of a given unit rapidly decreases. A standard Screw Conveyor inclined 15° upward will carry 75% of its rated horizontal capacity. At an inclination of 25°, a standard conveyor may only handle 50% of its horizontal capacity.
A screw conveyor is a versatile machine capable of fitting a wide verity of applications and moving an almost infinite range of bulk materials. One of the first questions asked when designing a screw conveyor is how is it being fed? This is a critical question and has a huge influence on the design of the inlet, trough, flighting, and drive.
Typical Conveyor Capacity. 1 in = 25.4 mm; 1 ft 3 /h = 0.028 m 3 /h ; 1 ft/min = 5.08 x 10-3 m/s; The product cross sectional area is defined by the idler trough shape and the product pile on top of the idler trough the trapezoid shape.

Note: High starting torque motors must not be used without design verification by Kase's Engineering Department. Example: A 12-inch carbon steel conveyor has been selected with a required shaft horsepower of 8.9 and a speed of 64 RPM. The drive to be used has an efficiency of 85%, thus requiring a drive input of 10.46 horsepower. Therefore, a 15 …

Normally short in length, Screw Feeders are designed to regulate the volumetric rate of material flow from a hopper, bin or storage unit. The inlet is usually flooded with material ( load capacity) but by incorporating changes in the construction of the flighting (diameter, pitch, etc.) and the speed of the feeder screw, the material discharge can be …
