A ball mill is a crucial piece of machinery used in grinding and mixing materials in various industries. It works by rotating a cylinder with steel or ceramic balls, causing the balls to fall back into the cylinder and onto the material to be ground. Ball mills are used extensively in the mining, construction, chemical, and pharmaceutical ...

Finally, conventional coal mill control is discussed in Lindsley (2000) and Liptak (2006). In the present work, a novel nonlinear coal mill model is derived for modelbased real time applications based on a former study (Mercangoez Poland, 2011). One of the objectives is to consider a tradeoff between model complexity and model accuracy ...
