Abstract
The invention discloses a boiling type concentrating machine. Original ore pulp is conveyed into a spiral rotating hub through a feeding device in a peripheral feeding way, and moves downwards along the inner wall of the spiral rotating hub and a spiral line under the action of centrifugal force; and compressed gas in an air casing is sprayed into the spiral rotating hub through a gas spray device, and high-pressure water in a water jacket is jetted through small holes in the inner wall of the spiral rotating hub, slurry is overturned continuously, and the motion of an internal suspension is intensified, so that delamination of slurry is realized under the actions of centrifugal force and gravity force. Finally, ore concentrate is conveyed to the bottom of the rotating hub through a screw and enters an ore concentrate pipe, and tailings overflow through a hollow shaft of the feeding device, so that separation is realized; and meanwhile, an air compressor arranged in the concentrating machine is used for continuously charging high-pressure gas into the ore concentrate pipe, and small-density media are blown back into the spiral rotating hub, so that the aim of secondary separating is fulfilled. The invention provides novel gravity concentration equipment in which concentration principles on the aspects of gravity concentration, centrifuging, floating, precipitating and the like are utilized comprehensively and the production practice advantages of gravity concentration equipment of multiple types are combined effectively.
