Abstract

1,159,149. Mineral-mining machines. COAL INDUSTRY (PATENTS) Ltd. 13 Dec., 1966 [15 Dec., 1965], No. 53247/65. Heading B1F. The diameter of a, preferably . single start, screw conveyer 26, 27 of a mineral-mining rotary cutter is less than the overall diameter of the area cut by roller cutters 21, 22, 23 mounted on a disc 20 secured to the leading end. of the conveyer. The head has a central roller cutter 21, an outer ring of roller cutters 23 and roller cutters 22 located about the head between the roller cutters 21, 23. Dust created in the vicinity of the roller cutters is suppressed by fluid emerging from conduits 29 in the head.
