The kwS Screw Conveyor Engineering Guide will provide assistance in the design of a screw conveyor or system, yielding optimum performance and efficiency primary considerations for the selection of a screw conveyor are: 1 Type and condition of the bulk material to

Screw conveyors transfer bulk materials volumetrically and capacity is calculated in cubic feet per hour Screw conveyor capacity is affected when the flight pitch is reduced from standard full pitch Reducing the flight pitch reduces the capacity For example, a 1/2 pitch screw carries 1/2 the capacity of a full pitch screw at the same level

The main parts of a screw conveyor are, screw blade, screw shaft, trough, inlet and outlet gates, bearings and drive mechanism The screw conveyor is generally used to move grains horizontally However, it can also be used at any angle upto 90° from the horizontal, but the capacity correspondingly reduced as per the inclination of conveyance

A screw conveyor helps in effectively moving bulk products at ceiling height It is inexpensive to purchase and virtually maintenance free; this is why augers are the best type of machinery when you’re looking for a lowcost solution in conveying finegrained or smallsized materials in bulk

Drive Shafts: A screw conveyor drive shaft is an essential component as it transmits the rotary motion from the drive unit to the conveyor screw Because of the nature in which the shaft is being used it is made from a highstrength highquality coldrolled steel to

Use these 2 to 3foot conveyor sections alone or add to a roller conveyor to rotate and position material along a conveying line Ball Transfer Extensions Add length to a ball transfer conveyor with these 6" long extensions or integrate them into a roller conveyor for multidirectional movement

A screw fitted directly to a hopper upstream is often referred in the literature as screw feeder while the equipment alone is often referred as screw conveyor The screw conveyor takes sometimes the denomination of Auger screw A typical screw conveyor design is shown below : Figure 1 : Screw conveyor principle drawing and key components

It enables the movement of the screw conveyor and telescopic chute upwards and downwards When the system is installed in the area, the screw conveyor is lifted to 45º angle with the help of automatic screw jacks When loading is over, the screw jack lowers the screw conveyor automatically to the horizontal position 2 units work in parallel
