It mainly shows in the following works:
1. Classification for section I closed circuit grinding
2. Classification for section II closed circuit grinding
3. Regrinding for fine mine classification
4. Mud-removing before selection and after selection
Dam and backfill for gangueIn closed circuit grinding system, it features high classification efficiency and fine overfall fineness under high mine concentration.
Classification efficiency is higher for 5-10% than common screw grader. It benefits for enhancing grader utilizing coefficient.Choose proper specification and mode of cyclone
according to grinding processing capacity, overfall fineness and sedimentation concentration.
This is precondition of getting the most optimized work condition.
Our company is able to offer stand-alone, parallel connection machine or machine series in such specs as Φ75, Φ100, Φ125, Φ150, Φ200, Φ250, Φ300, Φ350, Φ500,Φ610,Φ660 and Φ750.Fine sand, less than 37μm, in gangue can not be used as dam materials during selecting mine. After the classification by cyclone, coarse granule left in the bottom of dam, fine granule move to the tail of gangue. Fine granule graded naturally during the movement. There is section full of clean water, which can be used for calling back of water. In the process of filling tail, we utilize cyclone for grading and concentrating to separate coarse granule so that to reduce load of filtering machine and to reach at the best effect. Use cyclone to finish dam and filling work so that to solve problems such as leaking mine, sink and overproof water discharged. So it can receive obvious economic and social benefit.
