Abstract
17,087. Johnston, G. July 22. Roller mills for crushing or grinding auriferous quartz and other hard ores or substances. The ore &c. is fed, with or without water, at a slow speed and in a thin stream between rollers which are of different diameters and rotate with a high peripheral velocity. The apparatus comprises two crushing or grinding units, each consisting of a pair of rolls a, b of small diameter arranged adjacent to each other and between a pair of large rollers c, d. The rolls are driven by an endless band p passing round a pulley i on the driving shaft k and round pulleys h on the roller shafts e, so that the rolls a, b rotate in opposite directions to each other and to the adjacent roll c, d. Each roll is made with a renewable hard steel sleeve suitably fixed on the roll core or body. The rolls may run in contact with each other near their outer sides and be provided with peripheral grooves q to prevent the ore from escaping laterally. The ore is fed with water down a launder r into hoppers s, t, through the bottom of which it falls in thin streams between the rolls. The entrance to each receptacle s is provided with a perforated distributing-plate v. The ore may be treated successively in two or more such mills.
