FIELD: mining.
SUBSTANCE: invention relates to an apparatus for the milling cutting of rock, minerals or other materials in particular of hard materials. Apparatus for the milling cutting has a tool drum working member, which is mounted on a drum carrier rotatably about a drum axis and on the peripheral shell surface of which are disposed, in distributed arrangement, a plurality of tool carriers which carry cutting tools. Tool carriers can be rotatingly driven, wherein their shaft axes run transversely to the drum axis. It is proposed with the invention that a first group of tool carriers and a second group of tool carriers are provided, wherein the rotational direction of the first group is counter to the rotational direction of the second group.
EFFECT: technical result is good milling cutting results for cutting tools in both rotational directions of a tool drum working member.
