1.Monitor crushing granularity in time
We can't change the hardness of ore, so we should start with the crushing grain.The adjustment of crushing particle size is important.The staff must supervise the crushing system, and if the size of the grain is changed in the production, it must be reflected to the crushing workshop immediately.Finally, the finer the granularity, the better.
2.Steel ball ratio, choose high quality liner
Steel ball ratio has a certain degree of influence on the fineness of overflow ball mill, it should follow adding amount of steel ball and configuration method in the instructions. Lining plate should choose wear-resistant.
3.Optimizing classifier
The lifting height of spindle of classifier is also an important factor that affects sand return and grinding fineness.General normal production requirements, grading machine spindle put in place.After the equipment repairs, because the ore and sand of the grading machine did not clean up, can not put the spindle down completely, resulting the amount of returned sand is less. In addition, the spindle did not put down,maybe due to the spindle did not clean oil for a long time. So in the process of operation,worker must pay attention to these problem.
