Material Horsepower A straight edge placed at the first two known values, conveyor capacity and Material Horsepower Factor, will intersect a reference point on the centerline. A straight edge from the reference point to the third known value, conveyor length, will intersect the unknown value, Material Horsepower, on the last line.

Care should be taken to empty the conveyor before shut-down to avoid overload start-up conditions. Due to the fallback created in inclined screw conveyors by tumbling and agitation, the amount of material being pushed forward through the conveyor is reduced. To offset this loss of capacity, increased screw rotation is applied.

Since you have asked the questions using two mass units per time, I am assuming you are trying to compute the rate of delivery of some number or volume of screws per unit of time to the end of the conveyor. This simple computation could take sever...

The first type of screw conveyor was the Archimedes' screw, used since ancient times to pump irrigation water. They usually consist of a trough or tube containing either a spiral blade coiled around a shaft, driven at one end and held at the other, or a "shaftless spiral", driven at one end and free at the

It is done by drawing two ellipses one centered in the other. One ellipse is the width of the thickness of the root diameter of the screw with a length that fits the root diameter

14-7-2014· Based on MY interpretation of what my little slide rule indicates that if you're moving 10,000 lbs of portland cement per hour in an 20 inch diameter screw that is 45% (max recommended) loaded, the screw speed should be about 100 RPM. If the conveyor is 100 feet long the HP required is about 1.4 HP to move the material.

Derivation of the exact formula. To calculate the exact length of the spiral, we write the equation of the curve in polar coordinates: Here ρ is the distance between the axis as a function of the angle φ. φ is expressed in radians and is 0 at the beginning and increases by 2π every turn. So, every turn the radius ρ increases by h.

screw conveyor calculations As a specialist in the field of conveyor technology, Bechtel can also help you with design questions of screw conveyors. We provide you with the basic calculations for the determination of screw conveying speed, capacity per hour, weight of the material to be conveyed, as well as the calculation of the required power.

A screw conveyor with tubular housing and reduced pitch screw (1/2 or 2/3) is recommended for most applications. Loss in efficiency can also be overcome by increasing the speed or the diameter of the screw conveyor. Additional horsepower is required to overcome gravity and bulk material fall back.
