A vessel to remove solids from the tailings effluent as in a coal washery. The tank is about 60 ft (18 m) in diameter and 10 ft (3 m) deep. The tailings are fed in at the center with a flocculant. As the suspension travels from the center to overflow at the perimeter of the tank, the solids settle out and the clear water overflows, is collected, and is returned to the washer for reuse.
Industry:Mining
A vibrating conveyor in which the center of gravity of the complete assembly is held constant by having movement of the trough offset by opposite movement of some other element.
Industry:Mining
A vibrating conveyor in which the rate of free vibration of the trough on its resilient supports is approx. the same as the rate of vibration induced by the driving mechanism.
Industry:Mining
A vibrating ore screen in which the feed is from a saucer-shaped distributer onto a conical surface kept in vibration by a ratchet motion.
Industry:Mining
A vibration drilling technique that can be used in drilling, cutting, and shaping of hard materials. In this method, ultrasonic vibrations are generated by the compression and 3430 extension of a core of electrostrictive or magnetostrictive material in a rapidly alternating electric or magnetic field. The most easily assembled is a magnetostrictive transducer, and the most common magnetostrictive materials, which change in dimension when magnetized, are nickel and vanadium permandur.
