A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a quot;flightingquot;, usually within a tube, to move liquid or granular are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semisolid materials, including food waste, wood chips
MetaLine Series 700 coatings can protect pressureless screw conveyors and troughs against wear and tear. The clearance between the screw and the trough shall be at least times as large as the conveyed material to prevent jamming between the wings and the elastomeric protective skin.
The screw and conveyor surfaces can also be covered with a nonstick coating, Common examples are limestone exiting a kiln and fly ash discharging from a boiler. A screw conveyor can be designed to cool the material as its transferred for instance, A cooling screw conveyor with twin screws is shown in Figure 2.
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 of trough loading and speed.
Bottom ash conveyors should be designed and constructed to incorporate advanced features that add to the overall performance of the conveyor system. For example, watertight bearings are essential if using a wet bottom ash handling system, like a submerged conveyor.
The coatings can be engineered for your specific application. The flight design of the screw conveyor can be modified to be a ribbon or even a shaftless type. Ribbon and shaftless screw conveyors are designed specifically for conveying sticky bulk solids. Sticky products adhere to the screw at the location where the flight meets the center pipe.

As part of our ash conveyor equipment line, Process Barron designs, fabricates and installs custom designed submerged drag conveyor systems for solid fuel bottom ash applications. ProcessBarron bottom ash submerged drag conveyors feature special watertight bearings and heavy duty welded chains that reduce stretching common with dual strand submerged conveyors.
Screw conveyors Spirotech Group design, manufacture and supply complete screw conveyor systems. Spirotech Group has been designing,manufacturing and delivering screw conveyors since the companys inception in 1979. As one of its foremost products Spirotech has strived to deliver a better quality product and service than its many competitors.
Fly ash drag conveyor systems from Process Barron come complete with motors, drives, couplings and gear reducers. ProcessBarrons typical ash conveyor design incorporates a single strand chain made of high strength drop forged CrMn steel. The fly ash conveyors forged links are heat treated to a surface hardness of 59/64 HRC to a depth of 0
