NEW CRUSHING MACHINE.

—o— Rosche’s Patent Direct-acting Steam Battery, for the reduction of quartz, has, says the Australasian, been before the public for some time, and has been already noticed in our columns. It has now been brought forward, with modifications and improvements, and, its new form, it has met with the approval of scientific men and practical quartz-miners. A practicable model of the machine is on view at t.e Ynlcixn Foundry, in a’Aecket-street, Melbourne, and a short time ayo this was seen in motion by many gentlemen well qualified to pronounce an opinion on its merits, and performed to their entire satisfaction. Rasche’s battery is a machine that works somewhat in the way of a steam hammer. Besides a boiler, cylinder, ami piston, and the necessary stamper, it has scarcely any other gear. Steam is admitted under the piston, wl-'chin rising carries up the stamp shafts (four in number) along with it. The necessary elevation having been reached, the stamps are liberated by a simple contrivance, and fall’ng upon the quartz under treatment, perform the desired crushing process. The chief merits claimed for the machine are cheapness and portableness. A fourstamp battery wilt cost 150/., the stumps being five bundled weight each, and the whole machine weighing about three tons, and the number of strokes varying from sixty to one hundred and twenty per minute, according to the area of the tables and the velocity of the discharge of the tilings. No part of t .e machine, we are informed, except of course the boiler, is beyond the power of a horse to carry on his back, and if the machine proves as efficient in practice as it promises to be, it will prove the means of introducing quartz-crushing apparatus into legions quite inaccessible to a dry reducing machinery. Persons interested in a quartz country difficult of access should see Rasche’s machine, and form their own judgment as. to its merits.
