A PATENT QUARTZ CRUSHER
[From Our Own Correspondent.]
WELLINGTON. August 7,
Mr Wm. Watson, of Garrick (Otago), has invented a quartz crushing machine, the merits of which Mr Pyke has brought under the notice of the Goldfields Committee. Its chief claim to attention is that it can be cheaply worked. It does not exceed 30cwt in weight, is self-feeding, easily portable, and will crush 15 to 20 tons per week with a quarter of a sluice head of water and a pressure of 90ft perpendicular, while its cost will be from LIOO to Ll5O. His scheme is that the ore shall be crushed in a one or three-stamper battery; that the tailings shall then be discharged into a centrifugal convex and concave grinding mill, where they are reduced to flour; next be caught in a circular trough of mercury; then pass on and drop 10ft or 15ft into another quicksilver bath for amalgamation. The cams are on the same shaft as the driving wheel, so that there is no gear to break. Mr Watson has found his reef, himself taken out forty tons, built his battery, and crushed the stuff within five months, doing everything single-handed. The Committee have decided to forward the plans to the Mines Department for consideration.
