coal jet flotation
The jet flotation machine is a coal flotation equipment independently developed in China. It achieves aeration flotation by utilizing the negative pressure generated by the high-speed pulp flow passing through the jet injector. Its core component, the inflation and stirring device, integrates the functions of inflation, stirring and circulation, and has advantages such as microbubble precipitation and emulsification of chemicals.
Simple structure, no moving parts: The equipment operates stably, has a low failure rate, and is easy to maintain and operate.
Low energy consumption: The energy consumption per unit processing capacity is significantly lower than that of traditional flotation machines, achieving remarkable energy-saving effects.
High processing capacity: The processing capacity per unit volume is 6 to 10m³/(m³·h), suitable for large-scale production.
Strong microbubble precipitation capacity: It can generate a large number of fine bubbles, increase the flotation speed and the recovery rate of clean coal, and is especially suitable for the flotation of fine coal slime.
Emulsification function of the reagent: It can emulsify the flotation reagent into fine oil droplets, improve the dispersion of the reagent and the efficiency of bubble mineralization, and reduce the dosage of the reagent by
Uniform aeration and high separation efficiency: The bubbles are evenly distributed, the aeration volume utilization coefficient is high, there are no dead zones in the flotation cell, and the separation effect is good.
Strong adaptability: It can handle refractory coal and fine-grained coal slime, and is suitable for different coal qualities and complex mineral compositions.
Easy to automate and scale up: The equipment operates smoothly and is convenient for achieving automated control, making it suitable for large-scale production in modern coal preparation plants.
