Rotating cutting drum having tapered and curved conveying surface |
摘要 |
A cutting tool, particularly for a mining machine includes an elongated support having a first end and an axially spaced second end. The support also includes an outer circumferential surface having at the first end a first outer dimension and at the second end a second outer dimension which is smaller than the first dimension. The outer surface includes a portion adjacent to one of the ends and having a non-linear configuration with an exterior dimension which gradually decreases in direction from the above-mentioned one end towards the other of the first and second ends. A plurality of cutting units are located on the outer circumferential surface of the support along a line circumferentially embracing the support.
