Ruuvisyöttimet

Ruuvisyöttimet, also known as screw feeders or screw conveyors, are mechanical devices used to convey or feed bulk materials. They consist of a trough or tube and a helical screw rotor that rotates within it. As the screw rotates, it pushes the material along the trough from the inlet to the outlet.

These devices are versatile and can handle a wide range of materials, from fine powders and granules to larger lumps and flakes. They are commonly employed in industries such as agriculture, food processing, chemical manufacturing, and mining. Ruuvisyöttimet are valued for their simple design, reliability, and ability to control the flow rate of materials. They can be designed to move materials horizontally, vertically, or at an incline.

Different types of ruuvisyöttimet exist, including standard screw conveyors, live bottom screw feeders, and volumetric screw feeders. The specific design chosen depends on the characteristics of the material being handled, the required throughput, and the application. They are often constructed from materials like stainless steel or carbon steel to withstand corrosive or abrasive conditions. Maintenance typically involves lubrication of bearings and inspection of the screw and trough for wear.
