Screw Conveyors And How They Work

By Timothy Gibson


Mechanical systems for transferring materials in a production process automate this process the best they can. Makers of these have innovated and created better ones that are now in use across many industries. There are so many kinds of materials available as well as products of this kind, all benefitting production for companies that use them.

The handling of products in volume quantities is thus made easier, making the processing for them more streamlined. Screw conveyors may be efficient in transferring items to and from phases of one entire process. These are spiritual descendants of a system that is still in popular use in a lot of places for industry today.

There are two types of this kind of this automatic transfer mechanism, and these are the cranked screws and the crankless ones. Both are used for different processes, but the ones without cranks are more useful and efficient in many kinds of operations. The cranked system was discovered first, and the latter is a newer innovation.

Screws with cranks are those that are very useful still in many applications, since the processes are primarily efficient and workable. The latter of course will have the empty middle space which helps to pass materials through easily. But one disadvantage of the cranked screw is that it can be blocked up much faster than the other type of conveyor.

These may be only operated at horizontal, but are sometimes inclined when the needed passage requires it. Things able to move through these can be granular, liquid, or semisolid. Items can include things like boiler ash, food and solid waste, grains, chips, feeds for animals, food items, aggregates and some other products.

The screws are simply turned on and then run with either batteries or electric power. They will then transfer the materials to their prepared spaces, and perhaps crated out to some plant for disposal. The process is continuous as long as the screw turns and blockage, although it is expected from time to time, will be limited by this movement.

There are many innovative uses for these mechanisms as well, and they can be in the food industry. Although these are still studies, there might be found a way to make food processing easier with these. The types have varying kinds of rotation, based on the way they are designed.

The said kinds of screws will be attached in certain attachments, one is driven at the other end and anchored on one. Number two type will be free at one end and driven on another. The rotation speed is done with some controls that can either be manual or digital, and can address most needs for transferring materials in large volumes through the necessary space.

The quantities being fed into the system are measurable, and therefore their production can be calculated for. Basically, they are fast and efficient conveyors that handle loads all day, if need be. They are either run with batteries, stand alone generators, or through the grid, and some are powered by their own engines fueled by gasoline or gas.
