What is the significance and measures to improve the speed of flotation?

Flotation speed refers to the flotation time required when a certain recovery rate (or flotation unit production capacity) is reached.

Increase recovery and shorten flotation time, which is to increase flotation speed. Therefore, increasing the flotation speed is the main work that should be paid attention to and researched in mineral processing .

The main measures to increase the speed of flotation are:

1) Reasonable adjustment of the prescription, pay special attention to the amount of foaming agent. In general, a slight increase in foaming agent will promote flotation speed. It must be noted: Excessive foaming agent will reduce the selectivity, therefore, in the case of a large selection of the time and the amount of collector, attention should not excessive amount of foaming agent.

2) In the appropriate range, increasing the speed of the flotation machine impeller, reducing the depth of the trough, and reducing the impeller and cover gap, etc., at best, can promote the flotation speed.

3) Pass the slurry through the flotation tank as soon as possible. The series trough is faster than the open trough, which also helps to increase the flotation speed.

4) The size of the selection slot must be appropriate. Generally speaking, the size of the selected tank cannot be too large. The selection tank is too large to allow the slurry to stay in the tank for too long. Not only will the concentrate foam be depleted, but it will also reduce the flotation rate.

5) Control the appropriate slurry concentration to get the maximum flotation speed.

Silicone Cup Lids

About silicone lids for cups
As we know,each cup has a lid,most of cup lid are made of glass or ceramics,but we also know that they break easily.And sometimes we need find something replace glass cup lid,and keep the cup beautiful.
But,what we can use to replace the glass cup lid?
How about Silicone Cup lid?It's made of green material ---Silicone
Silicone material is eco-friendly material,we don't worry about it will be harmful our body.It won't broken even we throw it heavily.
And it can prevent the dust into our cup inside well,and it won't so ugly,you can do the design according to your hobby.
Choose silicone cup lid,improve your life style.
