Bucket elevators have been developed from belt bucket elevators and are specially designed for coarse, highly abrasive bulk materials. They are particularly suitable as recirculation units behind high-pressure roller mills, which are increasingly used for pre-grinding in the cement and ore sector. Useful for jobs requiring the movement of materials between different floors, and utilizing limited space in production and factory layouts. This design allows for multiple in-feed and discharge positions with selective deposition if required.
