There are two "inputs" to a ball mill circuit: the ore fed to the circuit and the power delivered by the grinding mill. A ball mill circuit has two "efficiencies": that of the ball mill grinding environment* and that of the classification system*. A ball mill circuit has two efficiencies because it has two main functions:
Casting defects formed in the preparation process of casting die steel are inevitable, [5][6][7] such as inclusion, trachoma, lack of meat, porosity, shrinkage cavity, shrinkage porosity, and so on.
