ruuvinsyöttölaite

Ruuviinsyöttölaite, often translated as a screw feeder or auger feeder, is a mechanical device used to deliver a controlled flow of bulk materials, typically granular or powdered solids, into a process. It operates by rotating an internal screw (auger) within a trough or tube. As the screw rotates, its flights move the material from an inlet hopper or chute towards an outlet.

The design of a ruuviinsyöttölaite can vary significantly based on the application. Key features include the screw diameter, pitch, length, and the material of construction, which must be compatible with the substance being conveyed. The speed of rotation is a critical factor in controlling the feed rate, which can be adjusted to meet specific process demands. Some feeders are equipped with variable speed drives for precise control.

These devices are commonly employed in industries such as agriculture, food processing, chemical manufacturing, and mining. They are used for tasks like accurately dosing ingredients, transporting materials between different stages of a production line, or discharging silos and hoppers. The enclosed nature of many ruuviinsyöttölaitteet helps to contain dust and prevent contamination, making them suitable for handling sensitive or hazardous materials. Maintenance typically involves lubrication and inspection of the screw and drive components.
