At first, you might think that the differences between the belt and tubular drag systems cannot be more obvious. The former is an open system with motor-driven pulleys moving a closed belt loop in one direction, and the latter is a closed system with a tube, chain or cable, and discs.However, a belt conveyor can also be closed, bringing it closer to a tubular conveyor design.
For most applications, it is recommended to use a screw conveyor with a tubular casing and a reducing screw (1/2 or 2/3) and a larger diameter. It is also necessary to increase the speed of the large-incline screw conveyor. Additional power is required to overcome gravity and loose material falling. Design and Selection of Inclined Screw Conveyors
Screw Conveyor Design. Screw conveyors are mechanical conveyors, just like tubular cable systems. They consist of a tube or a trough through which a helix (or an auger) rotates, moving the material forward as it does. Auger conveyors are great for moving materials such as: Meat, Animal feed, Grain, Boiler ash, Bone meal, Food waste,

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.
Screw Conveyors can be operated with the flow of material inclined upward. When space allows, this is a very economical method of elevating and conveying. ... Other aids in conveying on an incline are the use of shorter than standard …
Screw Conveyors are performing their assigned tasks in virtually all types of industries and, in addition, special designs are being developed for use ... styles of troughs …
Tubular – The tubular screw conveyor trough is useful for inclined applications (>15°) because the ID of the tube is ½" from the OD of the screw and helps to prevent the material from falling back over the flight as it is conveyed up the incline. The tubular trough is also useful for conveying sticky materials because the close ID/OD ...
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 All of the charts & formulas for calculating speed and capacity for a screw, in the horizontal are no longer applicable, what now comes into play is product knowledge and experience for sizing and calculating speed and horse power for incline and vertical screws.
The new KWS tubular screw conveyors operate on a 38-degree incline and proper screw conveyor design is very important for successful operation. The screws are mounted on larger-than-standard pipe to minimize deflection over …
for Vertical Screw Conveyors. As the degree of incline increases, conveying efficiency is reduced and horsepower requirements increase due to the effects of gravity and bulk material …

Elica's Screw Conveyor uses a rotating helical screw blade within a tube for transporting bulk materials. Screw conveyors can be operated with the flow of material inclined upward. This is a very economical method of elevating and conveying. The standard screw conveyor is made of electric welded steel tube with hanging bearings at every 2 meters.
Conveyor loadings may sometime exceed the recommended % of Loading, listed in the materials table. Considerations as to the material characteristics may justify up to 95% loading of tubular or shrouded conveyors.
Tubular housings are typically used when a screw conveyor is inclined over 15-degrees. Conveying efficiency is greatly improved with tubular housings because bulk materials are contained and fall back is reduced. ... Tubular housings are also used for weather-tight applications and used to hold internal pressure in a screw conveyor. ASME coded ...

SPIRAC's horizontal, inclined and vertical shaftless screw conveyors - with no intermediate or end bearings, low RPMs and low power usage - are an extremely reliable conveying option. For many facilities, space is at a premium, which is why the shaftless screw conveyor is designed to integrate into many configurations.
Inclined screw conveyors are used to move material at an angle, typically operating from slightly above horizontal to 60 degrees from horizontal, the conveyor consists of a screw located in a tube or trough, inclined at an angle to the horizontal .The screw rotates inside the tube, pushing the material up the conveyor. It is usually used in various industries to convey materials such …
