Abstract: 622.232.72 Owing to the increasing power of narrow-web cut~er-lo aders and the ur~ellability of existing cutter designs, it is necessary to create better cutters, which, in addition to improved reliability and service life, will have less energy consumption in the coal-cutting process and will give better-quality cut coal. One solution to this problem may lie in the use of conical-profile disk-type cutters, which can chip off large coal fragments, in cutter-loaders.The design, geometrical parameters, and …
