BF Flotation Machine

BF Flotation Machine

Flotation machine is also known as flotation cell, which is the important ore dressing equipment like magnetic separator. Flotation machine is mainly used for the flotation of materials, which is the crucial ore dressing in the flotation production line. It is suitable for processing ferrous metals, and non metals, such as coal fluorspar and talc. Service online

Detailed introduction

Basis Requirements of Flotation Machine

One of our main products, Jaw Crusher is designed by our engineers with large reduction ratio, even granularity, simple structure, reliable operation, convenient maintenance, low cost, Jaw Crusher is widely used in mining, metallurgy, construction, highway, railroad, and chemistry industries.

  • 1. A good effect of inflation.
  • The flotation machine must ensure that the slurry can absorb enough amount of air (the external pressure of some flotation machines are pressed by the fan) and try to diffuse throughout the whole groove. Because the air is more uniform with fine dispersion, so that the particle and gas saturation opportunities can have more contact opportunities, and its flotation efficiency is also higher.
  • 2. The stirring effect.
  • Flotation machine have to ensure the mixing effect on the pulp, so that the particle will not in precipitation state but in suspension state, which can be evenly distributed in the groove. At the same time, it can promote some insoluble drug dissolution, so as to contribute the full reaction between agents and mineral particles.
  • 3. Recurrent activities.
  • The circulating of pulp in the flotation machine can increase the contact opportunities between particles and bubbles.
  • 4. It must be able to adjust the liquid level and it can work continuously.
  • In the flotation process, it sometimes needs to adjust the thickness of the foam layer and slurry flow rate. From the feeding, the flotation of concentrate to the discharging of tailings is the continuous process.


  • 1. Large inflation amount, low power consumption.
  • 2. It has three functions of air suction, slurry suction and flotation. Self flotation circuit can work without any auxiliary equipment. Horizontal configuration is easy for process changes.
  • 3. Automatic control device of pulp surface, convenient adjustment.
  • 4. Reasonable pulp cycle can minimize sand sediments.
  • 5. Low energy consumption, less wear, easy automatic control.
  • ZENITH Machinery has large numbers of flotation machines for sale, which has high quality, simple operation and complete models, such as copper ore flotation machine and gold flotation machine. We can provide onsite installation and flexible configuration according to different production situations for customers. Welcome to visit our company!
