To Meet the Conditions of Improving the Speed

The flotation of the flotation-cell.html">flotation machine has a key role in the beneficiation production and other production lines, as for the flotation machine equipment; to increase the recovery rate and shorten the flotation time is to improve the flotation rate. Therefore, to improve the speed of flotation should be the main work in the beneficiation production.
Fluid dynamics state in the flotation tank of the flotation process is a very complicated three-phase hybrid system, there should be sufficient stirring intensity in the tank so that the pulp can be fully suspended and the mineral particles and air bubbles are in full contact, increasing the collision probability between the mineral particles and the bubbles, but the agitation in the flotation tank should not be too strong, which will would undermine the separation environment. Therefore, the three requirements must be taken into account in determining the speed of the flotation machine:
Stirring speed is greater than the critical speed required by the suspension of the solid particles: if the flotation process conditions are met, the value of the above formula should try to take the maximum in order to meet the requirements of industrial production, in the pulp, the  maximum particle equivalent diameter takes 1mm , ore density generally should be smaller than 4 × l03kg/m3, then the (PP-p) desirability should be 3 × l03kg/m3; solid-liquid mass ratio is generally between 20% -40%. X takes 40; water kinematic viscosity should be v = 10 ^-6m2 / s; k takes the value of maximum 150; in terms of new flotation machine, the impeller diameter should be D = 0.06m. Therefore, to make the particles reach the fully suspended state, the flotation machine speed must be greater than 764.92rpm.
