Problems solved by technology

Although they have solved the problem of continuous discharge of ore concentrates, they have not been widely used so far due to the disadvantages of water consumption, high energy consumption, poor economic effect, the need to add water purification devices to prevent blockage of high-pressure water flow nozzles, and poor mechanical stability. promotional use
The concentrate discharge method of the multi-gravity concentrator (MGS) is to use a mechanical scraper scraper, which makes the equipment structure complicated, the scraper wears a lot, and the price is expensive

Embodiment Construction

[0014] figure 1 The labels in it are motor 1, drum 2, casing 3, ore feeding pipe 4, washing water pipe 5, air flow nozzle 6, concentrate ore receiving tank 7, tailings receiving ore tank 8, frame 9, universal joint 10 and universal joint support 11, air pressure regulating valve 12.

[0015] The motor 1 drives the transmission mechanism to drive the drum 2 to rotate around the horizontal axis. The raw ore pulp enters the inner wall of the drum 2 through the feeding pipe 4, and is stratified and sorted under the combined action of centrifugal force and gravity; the washing water pipe 5 is fixed on the frame 9; the support shaft of the high-pressure air flow nozzle 6 is connected with the steering shaft through the universal joint 10, and the universal joint seat 11 is fixed on the frame 9, and forms a rotating pair with the steering shaft. The pressure of the air flow through the air nozzle 6 is 0.4Mpa. It can not only discharge the concentrate by continuous injection, but als...

Abstract

An airflow method and apparatus for discharging ore from wet horizontal centrifugal ore dresser are disclosed. Said apparatus is composed of rotary drum, casing, ore feeding pipe, water supplying tube, high-pressure airflow spraying pipe and machine frame. Its advantage is low water consumption.

Description

Technical field [0001] The invention belongs to a method and device for discharging concentrated ore from a wet horizontal centrifugal concentrator, more specifically, it relates to a method and device for discharging concentrated ore from a horizontal centrifugal concentrator by using the blowing action of high-pressure airflow. Background technique [0002] For all drum type centrifugal concentrators, the tailings can be smoothly and automatically discharged without any problems. Only the concentrate clings to the inner wall of the drum due to the strong centrifugal force and cannot be discharged automatically. Therefore, solving the problem of automatic and continuous discharge of concentrates has always been the key to the successful development of drum centrifugal concentrators. [0003] According to the relationship between the rotation axis of the drum and the horizontal plane, the centrifugal concentrator can be divided into two types: horizontal and vertical: if th...
