Ruuvikantajärjestelmät

Ruuvikantajärjestelmät, often translated as screw conveyor systems or screw feeders, are mechanical handling devices used to transport bulk materials. They consist of a trough or tube containing a helical screw blade, which rotates to move the material along the trough. The principle of operation is simple: as the screw rotates, it pushes the material forward from the feed inlet to the discharge outlet.

These systems are widely employed in various industries, including agriculture, food processing, chemical manufacturing, and waste management, for tasks such as conveying, feeding, mixing, and cooling of powdered, granular, or bulk solid materials. They are known for their robust construction, ability to handle a wide range of materials, and relatively simple design.

Ruuvikantajärjestelmät can be configured in different ways depending on the application. They can be horizontal, inclined, or even vertical, though vertical screw conveyors require specific designs to overcome gravity. Different screw designs, such as ribbon screws or paddle screws, can be used to accommodate materials with varying properties, like sticky or abrasive substances. Maintenance is generally straightforward, focusing on lubrication and checking for wear. Their enclosed nature also helps in containing dust and preventing material loss during transport, making them an efficient and often cost-effective solution for material handling needs.
