Värähtelijäannostelijat

Värähtelijäannostelijat, known in English as vibratory feeders, are mechanical devices used to move bulk materials from a storage area to a process or another machine. They employ vibration to move the material. The vibration is typically generated by an electric motor with an eccentric weight or by an electromagnetic actuator. This vibration is transmitted to a trough or bowl, causing the material within it to move forward.

These feeders are widely used in various industries, including manufacturing, mining, and pharmaceuticals, for tasks such as dispensing, screening, and conveying. They are particularly effective for handling granular, powdered, or small discrete parts. Värähtelijäannostelijat can be designed in various forms, including linear feeders, bowl feeders, and screens, depending on the specific application requirements.

The rate at which material is fed can often be adjusted by altering the frequency or amplitude of the vibration, or by changing the angle of the feed track. This control allows for precise dosing of materials into downstream processes. Their simple construction and reliable operation make them a popular choice for automated material handling systems. Värähtelijäannostelijat are known for their ability to handle a wide range of materials and their relatively low maintenance requirements.
