Description

Quartz powder independent classification system

Technical Field

The utility model relates to a quartzy powder stand alone type grading system.

Background

The intermittent ball mill is produced intermittently, and cannot be matched with a grading system for continuous grinding and grading, so when the average particle size of materials in the intermittent ball mill reaches ultrafine powder, compared with a continuous ball mill grading system, the intermittent ball mill has more ultrafine powder and more coarse particles, and the coarse particles of more than 20um of D504-5um ultrafine powder produced by the ordinary intermittent ball mill are within 5 percent.

The classification efficiency of the classifier is correlated with the cut particle size, the higher the classification efficiency, and the lower the cut particle size, the lower the classification efficiency. If the cutting particle size is 60um, the grading efficiency can reach more than 80 percent, and a large amount of products can be recycled; if need produce high-end superfine powder product, need amputate the coarse grain more than 20um, cut the particle size and set up to 20um, at this moment, the classification efficiency of grader is at 50 ~ 60%, can cause the waste of a large amount of products.

In conclusion, when the existing quartz powder independent classification system is used for independently classifying high-end ultrafine powder, the classification yield is too low under the condition that coarse particles are cut cleanly, and further a large amount of products are wasted
