For many mineral processing plants, tocontrol of grinding fineness and increase the recovery rate of ore concentrateis an important factor to increase enterprise benefit. So how to effectivelycontrol the grinding fineness, we must first fully understand the factors whichaffect the grinding fineness.

 

1. Ore hardness: It can have reasonable oreblending to make the mineral well-distributed and the massive and powder oreratio reasonable and balanced. In addition, at the ball mill feeding place, dueto long time abrasion, there may be ore leakage of the belt and most of themare mine smalls. This part of ore leakage must be promptly added to the mill.If they are piled up for a long time, they must be added intensively, causingthe uneven feeding and unstable production.

 

2. Crushing particle size: The ball milloperator must supervise the crushing system. If the feeding particle sizechanges in the process of ball mill production, it must be immediatelyreflected in the crushing workshop. The smaller the particle size is, thebetter it will be.

 

3. The ball mill type, rotate speed andfeeding capacity: Consult and communicate when purchasing.

 

4. Ball mill grading: Ball mill grading isan important factor affecting grinding fineness. With a group of professionaltechnical team, Xuzhou H&G Wear-resistant Material Co, Ltd. canprovide you with the best steel ball ratio guidance and help for the control ofgrinding fineness of ore dressing plant and the increase of the recovery rateof ore concentrate.

 

5. The grader principal axis can improve theheight. After the inspection of the equipment by the ball mill operator in somedressing plants, the circulating load will be little due to the uncleantreatment of the ore sand in the grader.

 

6. The blade abrasion: When the blade isworn, there will be little sand return volume and the ore grinding finenesswill be thicker.

 

We can do better improvement andmaintenance if we have a better understanding of the factors affecting oregrinding fineness.
