Ruuvisyöttö

Ruuvisyöttö, a Finnish term that translates to "screw feeder" or "screw conveyor," refers to a mechanical device used for the volumetric or gravimetric transport of bulk materials. It consists of a rotating helical screw (or auger) enclosed within a tube or trough. As the screw rotates, it moves the material along the length of the device. This method is widely employed in various industrial sectors for handling powders, granules, and other solid materials.

The primary function of a ruuvisyöttö is to move materials from one point to another, often over short to medium distances. They can be configured horizontally, inclined, or even vertically, depending on the specific application and the material's properties. The capacity and speed of the ruuvisyöttö are determined by factors such as the screw diameter, pitch, rotational speed, and the motor powering the device.

Common applications for ruuvisyöttö systems include the food processing industry for ingredients, the agricultural sector for grains and animal feed, and manufacturing for plastic pellets, chemicals, and cement. They are valued for their simplicity, reliability, and relatively low cost compared to other bulk material handling systems. Maintenance is generally straightforward, contributing to their widespread use. The design can be adapted to handle abrasive, corrosive, or sticky materials by selecting appropriate construction materials and screw configurations.
