The HAZEMAG Feeder Breaker HFB is a complete horizontal roll crusher plant, which operates on the field-proven principle of crushing in the horizontal material flow.

The Feeder Breaker consists primarily of two machine components: the crushing roll and the chain conveyor. The arrangement of the crushing roll above the chain conveyor allows the chain conveyor to be employed as both the feed conveyor and the discharge conveyor.

The design and arrangement of the picks on the crushing roll, as well as the scrapers in the conveyor, are main factors that determine the product size but, with the height-adjustable crushing roll and adjustment of the chain conveyor’s conveying speed, via a frequency converter, the granulation size can be adjusted to suit customer requirements.
