The optimization of processing plants is one of the main concerns in the mining industry, since the comminution stage, a fundamental operation, accounts for up to 70% of total energy consumption. The aim There are three types of grinding media that are commonly used in ball mills: • steel and other metal balls; • metal cylindrical bodies called cylpebs; • ceramic balls with regular or high density. Steel and other metal balls are the most frequently used grinding media with sizes of the balls ranging from 10 to 150 mm in diameter [30].Grinding in Ball Mills: Modeling and Process Control

NOVEL SIMULATION METHODS FOR MILL CHARGES
The pilot mill is 1.414 m in diameter and 1.22 m in length. It is a grate-discharge mill, equipped with 12 rubber lifters of square size 0.1 m and a face angle of 45 degrees. Steel balls with a diameter ranging between 10-30 mm and a density of 7800 kg/m3 were used in the experiments. The test material, a hematite pelletFinite Element Analysis. To ensure the structural integrity of the ball mill, a quasi-static stress analysis simulation was conducted on SolidWorks.
