What is a Concrete Screw Conveyor

Concrete screw conveyors are an alternative to belt conveyors. Instead of a belt, the mechanism used to move material is a screw blade. The helical shape of the screw is what moves the material.

Deca’s line of screw conveyors are especially designed for cement and flyash. Modular construction with all connections splined, heavy duty gearboxes, special intimidate bearings and swivel spouts.

Standard screw conveyors with motor, gearbox, inlet & discharge with same diameter as trough tube, motor and gearbox on inlet side.

Options: Drive on discharge end, heavy duty hanger bearings, and swivel spouts ranging from 6” to 12” on top and or bottom

Screw conveyors are especially designed for cement and flyash. These are modular in construction. Screw conveyors’ intermediate bearing engineered for minimum product obstruction, which transmits no torque and has better alignment. The bearing requires low maintenance.

Features and Benefits

• Designed specifically for the unique needs of the cement and flyash industries.
• Modular Construction
• Splined Connections
• Heavy Duty Gearbox
• Specialized Intimidate Bearings

Available Options:

• Drive on discharge end
• Heavy duty hanger bearings
• Swivel spouts ranging from 6” to 12” on top and or bottom

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!
