Syöttöruuvit

Syöttöruuvit, also known as screw feeders or volumetric feeders, are mechanical devices used to transport and dispense materials, often in a controlled manner. They typically consist of a rotating screw housed within a tube or trough. As the screw rotates, it engages with the material and moves it along the length of the screw, discharging it at the end. The design of the screw and its housing, as well as the rotational speed, can be adjusted to control the rate of material flow.

These devices are commonly employed in various industrial applications, including agriculture, food processing, chemical manufacturing, and pharmaceuticals. They are particularly useful for handling bulk solids, powders, granules, and pastes. Syöttöruuvit can be used for simple conveying purposes, but their primary function is often precise feeding or dosing of materials into a process. This precision is crucial in applications where consistent ingredient ratios or controlled reaction rates are necessary.

There are several types of syöttöruuvit, including single-screw, twin-screw, and helical screw feeders, each suited for different material characteristics and processing requirements. For example, twin-screw feeders can offer more vigorous mixing and handling of difficult-to-flow materials. Materials of construction for syöttöruuvit vary depending on the application, with stainless steel being common for food and pharmaceutical industries to ensure hygiene and corrosion resistance, while other metals or plastics may be used in less demanding environments. Maintenance typically involves lubrication and occasional inspection of the screw and housing for wear.
