Since we have talked about the effect of structural parameter and the technological parameter on spiral chute separator, but have you known there is also other factors that may have an effect on the separation of spiral chute. And today we will say something about it.
The effects of ore properties on spiral chute separator is in the following:
Effective sorting spiral chute feed particle size fraction is 74 ~ 20 microns, the chute is suitable for processing different diameter grade is different also, was elected don't iron ore, ф ф 600 mm and 400 mm spiral chute processing the granularity of the lower limit of 20 microns;ф 1200 mm spiral chute choose don't size limit to 30 m/mu.In order to obtain good effect, the spiral chute, like all other re-election equipment, requirements for material has a narrow particle size range.Therefore, rounding out the top and classifying the supplies will be very important.
Particle shape selected mineral grains assumes the circular, polygonal, flake or irregular shape, motion state in ore flow is vastly different.Similar to round a flake or diamond mine ore grain movement speed is fast, so the gangue minerals are rounded and heavy mineral flake or irregular shape, is very favorable for separation.
Mineral density in the density difference of objective mineral and gangue minerals in the ore the bigger the selected points.Evaluation for the mineral separation easily program, could be determined using the following formula: Type in the delta - purpose mineral density;The delta - gangue mineral density. When M1, the material can be sorting;The M = 0.75 ~ 1, separation effect is poorer.If M0.75, basically not separation.
In the process of spiral chute separator (http://www.chinaquarry.com/products_show/pro30.html), mineral sand is conveyed to the spiral chute by the feeding port, and to pour water to the chute at the same time can adjust the density of the mineral pulp with the features of top-down and rotary circle, which...
