APPARATUS FOR THE MILLING CUTTING OF ROCK, MINERALS OR OTHER MATERIALS.

摘要

The apparatus (14) according to the invention for the milling cutting of rock, minerals or other, in particular hard, materials which can preferably be used as a part-face heading machine (10) in underground mining, has a tool drum (15) which is mounted on a drum carrier (13) rotatably about a drum axis (16) and on the peripheral shell surface (17) of which are disposed, in distributed arrangement, a plurality of tool carriers (18), which carry cutting tools (19) and can be rotatingly driven, wherein their shaft axes (20) run transversely to the drum axis (16). In order to be able to mill out the rock or the like particularly effectively from the working face in both feed directions of the apparatus, which feed directions run substantially parallel to the drum axis (16), it is proposed with the invention that a first group (A) of tool carriers and a second group (B) of tool carriers are provided, wherein the rotational direction (21 A) of the first group (A) is counter to the rotational direction (21B) of the second group (B), and wherein, in a particularly preferred embodiment of the invention, the shaft axes of the tool carriers of the first group (A) and of the second group (B) are oriented at different setting angles (22A, B) relative to the radial direction (23) of the tool drum.
