Boiling type concentrating machine

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 screwand 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 likeare utilized comprehensively and the production practice advantages of gravity concentration equipment of multiple types are combined effectively.

Description

technical field [0001] The invention relates to mineral processing equipment, in particular to a boiling type mineral processing machine. Background technique [0002] With the rapid development of the mining industry, countries around the world are more concerned about resource utilization and environmental pollution, which puts forward a new requirement for mineral processing equipment: high efficiency, high cost performance and no pollution. Among the traditional beneficiation methods, amalgamation method and cyanidation method have serious environmental pollution due to the use of chemical agents, and improper handling is more likely to cause irreversible damage to the human body, while the cost of biological oxidation method is very high. Although the traditional gravity beneficiation method has the advantages of no need to add any chemicals and no pollution, its enrichment ratio is not high, and the quality of the concentrate cannot meet the needs of smelting, such a...

Problems solved by technology

Among the traditional beneficiation methods, the amalgamation method and the cyanidation method have serious environmental pollution due to the use of chemical agents, and improper handling is more likely to cause irreversible damage to the human body, while the cost of the biological oxidation method is very high

Although the traditional gravity beneficiation method has the advantages of no need to add any chemicals and no pollution, its enrichment ratio is not high, and the quality of the concentrate cannot meet the needs of smelting, such as jigging, chute, dense medium beneficiation, etc., or the production capacity is small , such as a shaker; these shortcomings restrict the development of gravity beneficiation equipment and the expansion of application fields
