Abstract：

Froth flotation is an effective separation method for fine minerals.Incorporated the principle of the flotation equipment with less power consumption,high energy conversion,two new types of flotation devices were designed by coupling jet technology.The effect of jet inspiration and stirring inspiration on particle size distribution of bubbles,bubble mineralization and flow field uniformity were researched.Jet inspiration and stirring inspiration aare combined in the Ⅱ type,which can realize large inspiratory capacity,uniform distribution of bubble size and stable flow field.The Ⅱ type is able to get large inspiratory capacity and uniform three phase flow field under the lower energy consumption and lower speed.The energy transformation and flotation efficiency are affectd by operating mode and structural parameters,such as inflow pressure,gas-liquid ratio,nozzle spacing,section ratio and so on. The flotation device achieves the purpose of pretreatment and flotation.

Key Words： jet inspiration;stirring inspiration;flotation;nozzle;inspiration way
