In order to solve the problem of low efficiency for fine particles flotation in reverse flotation of bauxite ore, a deep pneumatic flotation machine was designed to improve the flotation efficiency of ultra-fine particles for bauxite reverse flotation, and experiments of this flotation machine were also systematically carried out in reverse flotation for Henan bauxite resources. The main components of the ore flotation equipment(flotation machine for sale)are the slurry pile trough, the mixing device, the inflatable device, the discharging mineralization bubble device, the engine, etc.The impeller of the flotation machine is driven by the transmission spinning of the engine triangle to form the centrifugal formation and produce the negative pressure.
1. The slurry pile is trough: it includes the port feeding in the pulp and the switch device, which is made up of a trough welded and a switch both welded with the steel plate and the steel rod.
2. The mixing device: it is used for mixing pulp and preventing ores in the tub precipitation. It is mainly made up of the pulley, impeller made by the wear-resisting rubber and the vertical axis.
3. The inflatable device: it consists of catheter intake pipes. When the impellers are rotating, the negative pressure produced in the cavity of the impellers absorbs the air through the hollow pump line, which will be dispersed into the pre pulp and form the bubbles. The ore pulp with large amount of bubbles is thrown to the stators due to the rotating force of the impellers to fine the bubbles in the ore pulp and eliminate the rotating flow of the ore pulp in the flotation cell. Then large numbers of bubbles go up vertically to offer necessary conditions for the process of flotation.
4. The eliminating mineralization bubble device: it scrapes the bubbles above the surface of the cell, with the engine driving the reduction machine generally.
There are many reasons that can affect the flotation efficiency of iron ore concentrator, such as the granularity composition of the materials, the feeding size, the inflatable degree, the scrape of bubbles of fine ore, the content of drug, and the flotation flow. When flotation machine is working,after the bubble gets into the steady area, the bubble flows to the bubble cells from the down flow weir through the process of enrichment. Another part of ore pulp flows to the bottom of the impellers, through the mixture in the impellers forming the mineralized bubbles again. The rest ore pulp flows to the next groove until being the tailings.
