karuselliruokkija

Karuselliruokkija is a Finnish term that translates to carousel feeder or rotary feeder. It refers to a mechanical device used to control the flow of bulk materials, such as powders, granules, or small solids, into or out of a process. These feeders are characterized by a rotating rotor, often with pockets or cells, that picks up material from an inlet and discharges it at an outlet. The speed of rotation dictates the rate at which material is fed.

Carousel feeders are commonly employed in various industrial applications, including agriculture, food processing, chemical manufacturing, and mining. Their primary function is to provide a consistent and controlled rate of material transfer, which is crucial for maintaining stable process conditions, accurate weighing, and preventing dust emissions. They can also serve as a seal to prevent air leakage between different pressure zones.

The design of a karuselliruokkija typically includes a housing, a rotor, and seals. The rotor can be manufactured from various materials depending on the application and the nature of the material being handled. Options range from cast iron to stainless steel and even specialized plastics. The size and number of pockets on the rotor are designed to match the required feed rate and the characteristics of the bulk material. Maintenance usually involves checking for wear and ensuring proper lubrication.
