Abstract: A device for grinding a chimney to be lined comprises a grinding cutter (16) which can be raised and lowered, together with its drive motor, in the open cross-section of the chimney. The drive motor is a fluid motor (12) supplied via a fluid hose (14) by a fluid source (10) located outside the chimney (2). Also described is a process for grinding the chimney to be lined using a grinding cutter (16) which can be lowered through the open cross-section of the chimney prior to grinding and whose effective cross-section expands radially as cutting proceeds axially outward. As the grinding cutter (16) is lowered through the open cross-section of the chimney to be lined prior to grinding, the drive motor (12) is entrained through said cross-section together with said cutter.

Abstract translation: 用于研磨要衬里的烟囱的装置包括：与烟囱的开放横截面一​​起可与其驱动电动机一起升高和降低的磨削刀具（16）。 驱动马达是通过位于烟囱（2）外部的流体源（10）经由流体软管（14）供给的流体马达（12）。 还描述了一种使用研磨刀具（16）研磨待排列的烟囱的方法，该研磨刀具可在研磨之前通过烟囱的开放横截面而降低，并且当切割沿轴向向外延伸时，其有效横截面径向膨胀。 当研磨刀具（16）在研磨之前通过待排列的烟囱的开放横截面降低时，驱动马达（12）与所述切割器一起被夹带穿过所述横截面。
