    摘要： A milling device for excavating mining materials is disclosed. The milling device comprises a milling drum rotatable about a drum axis; a first group of excavating heads arranged around a periphery of the milling drum and driven to rotate about a first rotational axis extending substantially radially to the drum axis; and a second group of excavating heads arranged around the periphery of the milling drum and rotatable about a second rotational axis extending substantially radially to the drum axis. The first group of excavating heads includes a plurality of first excavating tools configured to perform a first, cutting operation, and the second group of excavating heads includes a plurality of second excavating tools configured to perform a second excavating operation different from the first, cutting operation.

    摘要： A milling device is disclosed. The milling device may have a shaft. The shaft may have a shaft axis (A). The milling device may also have a spindle drum rotatably mounted relative to the shaft axis (A) and rotatable about a spindle drum axis (B) coaxial to the shaft axis (A). Further, the milling device may have a plurality of tool spindles rotatably mounted in the spindle drum and rotatable about tool spindle axes (D). Each tool spindle axis (D) may be parallely arranged and spaced apart from the shaft axis (A) and may have a same distance to the shaft axis (A). The milling machine may also have a plurality of machining tools carried by the tool spindles. At least two of the plurality of machining tools may be positioned displaced from one another in a direction of the shaft axis (A).
