How do I make the dry grinding process more efficient?

• In my mining company, we purchased a ball mill used in the dry grinding process. If we want to improve the production scale, we should improve the efficiency of dry grinding process.

• Answer:

  First, the smaller the feed size and the more uniform the feed size the higher the efficiency. Beyond that, the type of milling (http://mining.chinashibang.com/product/mtm_trapezium_grinder.html) raises a number of specific issues. Tips: 1. Minimize moisture content of feed material; high moisture content (over 2%) can cause material to cake inside the milling chamber. 2. Continously add grinding aids or additives, whether in powder or liquid form, while size reduction is taking place. Most dry milling processes require such materials. Their function is to do one or more of the following: a. minimize the effects of moisture inherent to the material be- ing processed; b. change the electrical charge on the surface of particles; c. reduce the negative effects of static charge that may develop; d. function as a lubricant between particles; and e. act as a partitioning agent between particles to prevent agglomeration. Trap: 1. Avoid over-grinding material that’s already smaller than desired size. Remove this fine material as soon as possible by some form of classification. This will increase process throughput rate and efficiency. Read More, you can refer to: http://mining.chinashibang.com/product/?name=grindingul
