Abstract
A milling roller module for a surface miner, includes a milling roller operating with undershot for loosening the material from the block being mined, a support frame for fastening the milling roller to the surface miner, and a takeup chute for supporting the intermediate conveying of the loosened material in the area of the milling roller and for transferring the material to the downstream discharge belt in a specific manner. The drives are placed into the milling roller and the feed lines are led into the milling roller together with the support frame for fastening the milling roller from the side in the upper third of the milling roller diameter. As a result, it is possible to perform mining operations up to a cutting depth that is equal to half the roller diameter. A takeup chute is provided to transfer the material from the milling roller onto the downstream discharge belt in a specific manner. This takeup chute is also used to limit the conveying space in the area of the milling roller together with ring segments arranged on it and on the milling roller and thus to reduce losses of material.
