Jet Flotation Machine

Microbubble Jet Type  Flotation Machine

Microbubble flotation machine is a compact, low-cost, high-efficiency microbubble jet flotation equipment other than flotation columns and conventional flotation machines, it  has no mechanical stirring mechanism using high-speed jets and fluid turbulence to achieve slurry aeration and mineralization.

Microbubble jet flotation machines have been the leading non-mechanical stirring flotation equipment for 30 years, and have been widely used in mineral processing flotation, fly ash removal, oil sand tailings deoiling and other fields.

 

  • When the micro foam floatation machine is running, the feed slurry is driven from the top of the flotation machine by the high-pressure pump, and the pressure energy of the pulp is converted into a fast flow jet through the nozzle at the upper part of the down pipe, and a negative pressure is formed in the sealing sleeve, and the air is sucked into the air through the air pipe, and the gas in the jet slurry rolls into the mineralized pipe, due to the highly turbulent action of the fluid. The gas is divided into numerous tiny bubbles and constantly collides with the ore particles to complete the mineralization process.
  • The mineralized bubbles are bubbling at the bottom of the underwash pipe, and float up to the pulp surface to form a bubble layer in the tank. The rising foam is discharged into the concentric trough after spraying and washing to be recovered.
  • The tailings slurry is discharged downward to complete separation.

Main Feature

Excellent  aeration performance and high mineralization efficiency

Short  flotation time and large treatment capacity ;

Large turbulence intensity and Strong  fine particle collection

Part of the tailings slurry of  TOMINE’S jet type  flotation machine flows into the raw ore pool. If the new feeding amount fluctuates, the amount of tailings slurry that flows into the raw ore pool will be adjusted accordingly to keep the liquid level of the raw ore pool constant and ensure the constant feeding
pressure of the flotation machine and the stable production process.

The floatation process and the bubble mineralization process of the TOMINE’S flotation machine are completed step by step in the undershoot pipe, which is different from the foam rising area, the concentrate area and the tailings area.

The operating conditions of each down flushing pipe of TOMIE’S flotation machine are the same, so it is easy to control and reliable to operate.

Pulp internal circulation , good environment for separation

Compared with conventional flotation machine:
  • 10% – 50% power saving
  • Flotation reagent saving 10% – 20%
  • No rotating parts
  • Less vulnerable parts
  • Low maintenance cost

High degree of self-control, easy operation and maintenance

  • Frequency control of feed pressure
  • Automatic detection and control of liquid level
  • Foam layer thickness adjustment is simple and convenient.
  • Replacement of spare parts does not require shutdown
  • Easy to operate, no need to guard

High beneficiation efficiency and small floor area

Jingrui flotation machine has high beneficiation efficiency, one equipment can replace one or even several flotation operations.

The processing capacity of the Jingrui flotation machine is calculated by the following flushing pipe as a unit. The volume of the cylinder is only used as the material transmission channel, in which multiple down flushing pipes can be inserted in parallel to increase the processing capacity of the whole system without affecting the separation index.

The installation land area of TOMIE’S  flotation machine can be saved 40% – 60%, which greatly saves the capital investment. In particular, the advantages of elite flotation machine are more prominent in the reconstruction and expansion of the old plant with tight space.

Wide separation size and wide application range

TOMINE’S New Vertical type flotation machine has wide separation size.

With its excellent performance, microbubble flotation machine has been widely used in the separation of coal, copper, lead and zinc, molybdenum, gold, nickel, antimony, platinum, graphite, cobalt, oil sand and potassium salt, etc., and has been widely used in various stages of flotation operations such as roughing, cleaning, scavenging and tailings re-concentration.
