Overview

The flotation machine is a kind of mechanical equipment that realizes the froth flotation process and selects the target mineral from ore. Since it was equipped with a concentrator in the early 20th century, its structural design has been greatly developed after many years of development.

- Applicable Materials:

gold ore, aluminum ore, lead ore, zinc ore, nickel ore, aluminum talc, bauxite, and potassium feldspar

How it works

As the impeller rotates, the slurry in the tank is sucked from the lower end of the impeller to the gap beween the impeller blades. At the same time, the low-pressure air fed by the blower enters the same place through the air shaft of the hollow shaft and the air distributor of the impeller. After the slurry and the air are pushed upward from the periphery of the upper impeller after they are fully mixed in the gap between the blades. The stator then stabilizes and orientates the mixture to enter the tank. The bubbles first rise to the foam stabilizating zone. After the collecting process, they overflow from the overflow weir and enter the foam tank. Another portion of the slurry flows into the lower part of the impeller, and then is stirred and remixed by the impeller to form mineralized bubbles. The remained slurry flows into the next tank until it eventually becomes the tailings.

Classification

There are many models for our flotation machine mainly including SF series, BF series, KYF series and XCF series, among which the BF series flotation machine is developed on the basis of the SF series one.

Outstanding Advantages

The SF Series Flotation Machine

1. The widened pulp area is useful for improving aeration capacity and reducing the degree of tumbling.

2. The high degree of foam refinement maximizes the flotation effect.

3. It features simple structure, high processing capacity, ease of operation and of maintenance.

The BF series Flotation Machine

1. It has low operating cost and saves one third or even one half of power consumption.

2. It features high sorting precision and reduces the fine coal ash by 1~2%.

3. It is equipped with liquid automatic control and electric control devices to enhance foam refinement and flotation effect.

4. The impeller of the stirring device is made of grinding rubber to improve its wear resistance.

5. The impeller consists of a closed double-section cone that can cause strong sub-slurry cycle.

6. With the functions of sucking air, sucking slurry and flotation, each slot can form its flotation circuit by itself without any auxiliary equipment.

7. The reasonable slurry circulation can minimize coarse sand sedimentation.

8. It has high sucking capacity and low power consumption.

KCF series and XCF series Flotation Machines

1. They adopt a U-shaped tank, a hollow shaft inflation device, a suspension stator and a new cone impeller that is similar to high-speed centrifugal pump wheel. Also, they have slurry in a large amount, a small pump head, low power consumption and simple structure.

2. A porous cylindrical air distributor is installed in the impeller chamber to allow air to be dispersed uniformly in most of the impeller blades in advance, providing a large slurry-air contact interface.

price

There are different kinds of specifications for the flotation machine according to the requirements for operating conditions, capacity and energy consumption; thus, its price varies.

FTM Machinery will offer price cuts to customers in light of your investment and we promise you are bound to get a high-quality flotation machine with great service at a favorable price. If you would like to inquire about the price, please click the online consultation.
