Abstract
The rotor of a cutter for removal of ore from mine faces has several external material removing bits which are mounted in holders at the exterior of the rotor, and the holders have sockets for discrete spray nozzles which discharge streams of highly pressurized water against the mine face and/or against the bits. The nozzles receive water from discrete conduits whose discharge ends are threadedly connected with the respective nozzles and whose intake ends are connected to the outlets of manifolds which are installed in the interior of the rotor. The conduits extend from the outlets of the respective manifolds and through holes which are provided therefor in the rotor. The sockets in the holders receive spherical joints which allow for changes in orientation of the nozzles with reference to the adjacent bits.
