Why Use a Screw Conveyor
  • Perfect for dealing with dry and semi-fluidious materials.
  • The most cost efficient way to convey cement
  • Easily distribute your bulk material to multiple locations with multiple inlets and discharges
  • Can be totally enclosed to address corrosion or protect hygroscopic materials from the elements.

Principles of Selecting Your Screw Conveyor
Establish General Performance Criteria
  • Items such as conveying distance, material considerations, and flow rates should all be considered
Classify Your Material
  • There are lots of factors that go into this process. Deca can help, but you should come prepared to discuss things like moisture content, abrasion, particle size, temperature and any other unique considerations your material might require.
Determine Capacity
  • This is typically measured in pounds per hour. Establishing your maximum flow rate will be critical to ensuring that your screw conveyor provides many years of service. Getting this wrong can mean production backups, early failure or early replacement for a larger model.
Determine Speed and Diameter of the Screw
  • Once you’ve classified your material and established the performance requirements, Deca can help you arrive at the equipment particulars that best address your specific needs.
Determine Components and Options
  • Because of our vast experience with conveying equipment, Deca can help you think through any potential challenges your particular situation may present and then pick the right components and options to address them so that you get the best possible outcome. We’ll discuss things like motor and bearing selection, flighting material and design in addition to much more.

About the Screw Conveyor
  • Archimedes is credited with developing the earliest screw conveyor as a means of removing water from a ship. While the basic principle of the screw conveyor has gone unaltered the internal helical design he employed and been refined via technological advancements of the industrial age. Today, screw conveyors are highly tuned, and can move materials in almost any direction. This flexible, cost efficient conveyance has shuttled them into use just about anywhere powders and liquids need to be moved. They are simple to install and require little to no ongoing maintenance. The screw conveyor is arguably the best all-around method for moving material in the world today!
  • Deca Vibrator is standing by to offer you experienced support in applying this essential method of bulk material conveyance to your operations. Don’t delay, call us today!

N/A ES Screw Conveyors are manufactured in carbon steel with a suitable surface finishing and powder coating. They are made up from a tubular trough that is equipped with at least one inlet and outlet spout, a welded flange at each tube end, helicoid screw flighting welded on a centre pipe with a coupling bush at each end, two end bearing assemblies complete with self-adjusting shaft sealing unit (one of the bearing assemblies incorporated in the drive unit), a number of intermediate hanger bearings depending on the overall length of the screw conveyor. Furthermore, ES Screw Conveyors are equipped with a gear motor that suits the application.
ES Screw Conveyors are of the medium-heavy-duty type.

Applications

N/A In over forty years the ES-type Screw Conveyor has become a synonym for cement feeding and conveying in concrete batching plants all over the world. In this period Deca Vibrator industries Inc have supplied many units which have been operating ever since. After the turn of the new millennium it is hard to find a batching plant manufacturer anywhere in the world who would not appreciate the unrivalled technical features and quality of the ES. Apart from cement, ES-type Screw Conveyors are nowadays also used for filler and other materials similar to cement
