We have talked about something about the effect of structure parameter on spiral cute before. So I think that most of you may know something about it, but do you know the effect of technological parameter on the spiral chute separator?

The effct of technological parameter on spiral chute separator is as follows:

The size of feed feed volume, directly affect the thickness of ore flow and speed.When separating coarse material feed volume should be large, choose don't fine grained material feed volume should be small.Roughing feed volume when appropriate, select feed volume should be small.Hematite production practice shows that, with the increase of feed volume, tailings grade rise, the concentrate grade is also slightly higher, metal recovery rate decline.Under the normal feed concentration, industrial ф 1200 mm spiral chute feed volume is 180 ~ 220 l/min.

Feed concentration feed concentration is too big, can increase the pulp viscosity, so that seam is bad, the particle sedimentation, influence layering effect and ore grain along the groove surface movement speed, concentrate grade and recovery rate of decline.And feed concentration is too small, not only reduces the processing power of chute, also make the ore material layer thin, does not have the density stratification, zoning of terms and conditions, and can make the slurry flow rate increases, re-election content to discharge at the delamination, settlement, cause the loss of tailings grade rise, the recovery is, however, the spiral chute is not sensitive to the change of seeding concentration, in a wider range of concentration, the
