As an example, a regular flight conveyor may be able to convey 9 tons/hour whereas a cut flight screw would convey 5.7 tons/hour. Cut and fold. This is a slight variation of the cut flight screw. Rather than completely removing material from the flight, a small section is cut and folded out of the flight, creating a small arm.
Step 1 : define the requirement. Define the capacity required for the screw conveyor. The design of the screw must reach a capacity equal or greater than this value. Example : the requirement for a screw conveying sugar is 3500 kg/h. Step 2 : calculate the capacity of the screw conveyor. Assume a diameter D.

The simplicity of the screw conveyor design allows it to be used in many different applications. Besides transporting flakes, powder, grains, and granules, screw conveyors often find uses as agitators and blenders, as well as for bottling system conveyors. Mini screw conveyors work well in moving concrete and other non-flowing …
Ribbon type screw conveyors use ribbon-type flighting that creates a gap between the center shaft and flights to prevent buildup of sticky material that often affects the normal operation. ... When handling sticky materials or for mixing needs a ribbon flight screw conveyor is recommended. Standard sections range from 6" up to 24" in diameter ...

A 16-inch diameter screw conveyor will convey 2,496 cubic feet per hour at the maximum recommended speed of 80-rpm. The actual screw conveyor speed is calculated by dividing the Selection Capacity by the capacity at 1-rpm. 1,873/31.2 = 60-rpm. 60-rpm is the correct speed for a 16-inch diameter screw conveyor with cut and folded flights and ...
Coupling Bolts. Coupling bolts are manufactured from various high-strength carbon steels and 18-8 stainless steels. KWS stocks Grade 5 carbon steel and 18-8 stainless steel coupling bolts. The shank length of a coupling bolt is equal to the measured outside diameter of the center pipe of the screw to provide maximum shear area and strength.

A screw conveyor is made of a housing, typically a tube or a U trough, in which is rotating a screw flight or auger (helical shaped blade) that allows to mechanically move bulk materials. The screw can be shaftless, or having a shaft on which is welded the helical blade. Screw conveyors are a very popular equipment in solids processing industry ...
As per the formula, outside diameter can be found by reducing the inside flight diameter from the outside flight diameter and dividing the resultant value by the 2. And to find the cylindrical screw flights, divide the products of developed inside diameter and overall radius by the reduced value of developed outside diameter and inside diameter.
