Request an estimateFor maximum efficiency a crushing circuit will generate a reduction ratio between 5:1 and 7:1 Using a two stage crushing circuit with a reduction ratio between 3:1 and 4:1 at each stage reduces fines and also decreases the number of particles filtered back to the crusher
Mineral processing procedures are complex and 70:1 is the maximum practical reduction factor (ratio) for a ball mill the target is 18 What is the crushing ratio (size reduction ratio) – kefid
