Vertical screw conveyors are an efficient method for elevating a variety of bulk materials from steep inclines to completely vertical. The compact design allows the vertical screw conveyor to fit almost any plant layout. With minimum moving parts, the vertical screw conveyor is a cost-effective and dependable component of any bulk material handling process.
A standard screw conveyor will often operate normally at angles up to 15º with only a small loss in capacity. Beyond that, adjustments and/or modifications are typically necessary. The design is a bit involved and these items should be taken into consideration:

Jan 09, 2008· Screw conveyors can be used to convey bulk materials at an inclined angle, but several areas of design should be examined first. Because of the incline of the screw, several conveying problems begin to occur. 1. The horsepower per unit of material increases 2. The efficiency of moving the material forward decreases.
This allows for direct connections and optimizes layout design flexibility. End-to-end and side connections not possible on shafted screw conveyors are common solutions available in the shaftless design. Vertical shaftless conveyors are available in a single unit up to 50 feet and systems in excess of 100 feet in elevation gain.

A 10-inch 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.
This Horizontal Screw Feeder feeds the powder to a Vertical Screw Conveyor. The Vertical Screw Conveyor is a tubular screw mounted at 90 deg to the Horizontal Screw Feeder to convey & elevate/ load the powder to the required height for filling into a weigh hopper and/ or one or multiple silos with a Distribution Screw (which is another ...
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 All of the charts & formulas for calculating speed and capacity for a screw, in the horizontal are no longer applicable, what now comes into play is product knowledge and experience for sizing and calculating speed and horse power for incline and vertical screws.
