Kierrejärjestelmien

Kierrejärjestelmien, often translated as screw conveyors or augers, are mechanical conveying devices that utilize a helical screw rotating within a trough or tube to move bulk materials. The rotation of the screw imparts a force on the material, causing it to move axially along the length of the conveyor. This system is particularly effective for handling powders, granules, and semi-solids.

The basic components of a kierrejärjestelmä include the screw itself, which can be a solid shaft with a continuous helix, a ribbon screw for sticky materials, or a paddle screw for breaking up lumps. The trough or tube encloses the screw, preventing material from escaping and guiding its movement. A driving mechanism, typically an electric motor, provides the rotational power to the screw.

Kierrejärjestelmien are widely used in various industries, including agriculture for grain handling, food processing for ingredient transfer, chemical manufacturing for material transport, and waste management for sludge dewatering. Their simplicity, robust construction, and ability to handle a wide range of materials make them a popular choice.

Advantages of kierrejärjestelmien include their relatively low cost, compact design, and enclosed operation, which minimizes dust emissions and contamination. They can also be configured for gentle handling of delicate materials. However, they are not ideal for abrasive or very fragile materials as the screw action can cause degradation. Maintenance typically involves lubrication and inspection of the screw and trough for wear.
