Flotation Separator is the main equipment of the flotation process. By the single slot or multiple slots in series, inflatable flotation slurry mixing, the adhesion of air bubbles and mineral particles, air bubbles rise and form a foam layer is scraped or overflow out in the flotation tank.

The flotation machine instructions:

1, the boot should be checked of various parts before working. The bolt stop should be preceded by the manual instead of the wheel rotation, to prevent sediment deposition to increase the motor load.

2, the work should be careful to adjust the gate height of the surface remained stable, and garantee at any time the surface mineralization of ore slurry bubble scraping inflow groove.

3, the impeller and the stator should be kept a certain distance, wear and tear should be paied attention to, replace the pump body bearing every three months as maintenance time.

Wearing parts: the impeller, the stator.The pneumatic flotation machine is made by the principle of flotation column which combines the advantages of both flotation separator and the flotation column and can effectively overcome the shortcomings of both.The majority of ore flotation impact crusher available for selection, beneficiation costs are higher.

This flotation separator is characterized by the simple structure, easy maintenance, the minimum amount of reagent, long service life of the wearing parts and high recovery rates which can reduce the energy consumption more than 80% and make full use of gas. The pneumatic flotation separator can greatly reduce the flotation process stage and the equipment and infrastructure investment to a maximum extent.Pneumatic flotation separator: First, the structure is simple without mechanical stirrer or transmission components. Second, the pneumatic feature: the pneumatic flotation separator is aerated by the aerator and the size of the bubble is adjusted by the structure of the aerator. Third, countercurrent mixing is the feature of the mixing bubble with slurry.

Use: the process is composed simple and the grade is relatively high, which is easy for coarse and scavenging selection to select the ore. In addition, the structure of the flotation column is easy with small footprint, easy maintenance, easy operation and power saving.The application of the flotation method is regarded as a significant achievement in the mining technology in the 20th century. Besides the continuous disposition of the increasing various ores and opening new ways, flotation plays a vital role in promoting and improving metallurgical technological and economic indicators, comprehensively recycling all kinds of valuable components. At the moment, 90% of the nonferrous metal mineral output capitalizes on the flotation method for recycling. It is reported that almost the entire ores and mineral raw materials can adopt the flotation way to get processed. In addition, the flotation method is also used in the comprehensive recovery aspect of the metallurgy semi-finished products as well as these perspectives like salts, borax, rubber raw materials, paper, sugar refining, and chemical processing of raw materials etc. stone crusher:http://www.hx-crusher.com/crusher.html

Beneficiation of the following: 1), gravity concentration method (referred to as the re-election): re-election is to use mineral density in the medium (water, air, re-solution or suspension) in movement speed or the trajectory of different achieve the separation method.This method is widely used to select the Do not tin, tungsten, gold, iron, manganese and other minerals such as, but also for sorting certain rare metals and, more generally used in coal preparation.Gravity concentration machines: jigger, shaker, chute, spiral concentrator and hydrocyclones, etc..2), zooplankton dressing method (referred to as the flotation method): Flotation is based on the wettability of the mineral surface, leaving the useful minerals and gangue are separated from each other by adding the appropriate pharmaceutical method.

As the professional manufacturer of complete sets of mining machinery, such as magnetic drum separator, Henan Hongxing is always doing the best in products and service.
