A 10inch conveyor 35 feet long with a capacity of 10 tons per hour at 45 RPM has been selected. From the Materials Table, a Horsepower Factor of 0.8 is found for the material to be conveyed. The table also indicates Series 4 hanger bearings and shafts.

SPIROLINE ® conveyors feature a Utrough with a low RPM shaftless spiral screw riding on a special low friction long life trough liner. Material handling can place a lot of pressure on equipment, as many of the industries SPIRAC serves feature harmful, possibly corrosive substances.

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. These are estimated figures and will vary with the characteristic of the material being handled.

Most CEMAapproved screw conveyor manufacturers have the capacity calculation and the CEMA guidelines as part of their screw conveyor design software. Inclined Screw Conveyors Inclined screw conveyors typically operate from slightly above the horizontal position to 45 degrees from the horizontal position. Above 45 degrees an inclined screw ...

A screw in the horizontal is a conveyor or feeder, but as a screw is inclined it very quickly becomes a lift or pump. All of the charts & formulas for calculating speed and capacity for a screw, in the horizontal are no longer applicable, what now comes into play is product knowledge and experience for sizing and calculating speed and horse power for incline and vertical screws.
