Chromium Processing | Process Flow, Cases

The ball mill is for grinding 0-20mm to small powder. It works together with the spiral classifier, so the overflow slurry from the classifier is about 80% 200mesh powder. The oversize particle from the classifier will go back to the ball mill grinding again, to form a closed-loop.

5 Comparisons to Think Before Choose a Spiral classifier …

2. Floor area. Obviously, the footprint of the hydrocyclone is significantly smaller than that of the spiral classifier. Usually, the area of the hydrocyclone is only 1/30～1/50 of the spiral classifier. The equipment footprint requirements also limit the application of spiral classifiers to a certain extent. 3.
