Mine mineral extracting roller cutter nozzle holder - is cylindrical unit cemented into full length tightly encircling hole

摘要

The hole, aligned with the fluid supply system and accommodating the nozzle attachment, is provided in a nozzle holder, esp. for cutter rollers on machines for extracting minerals in underground mines, located inside a recess in a cutter roller. The holder (1) is cylindrical in shape, and is cemented into a hole which tightly encloses it and provides accommodation for it along its whole length. This is easily made, and easily fastened in position, and is tough and free from mechanical stresses, but also easily removed for repair by heating the adhesive.
