Since heavy equipment retrofitting is the most costly approach, process optimization with dedicated models and control systems is the most preferable solution for energy consumption reduction. While the classic technological measurements in mineral processing are well adopted by the industry, nowadays research focuses on new methods of the mill\u2019s internal dynamics analysis and control. This paper presents a retrospective overview of the existing models of internal load motion, an overview of the innovations in process control, and some recent research and industrial approaches from the energy consumption reduction point of view.<\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('80','tp_abstract')\">Close<\/a><\/p><\/div><div class=\"tp_links\" id=\"tp_links_80\" style=\"display:none;\"><div class=\"tp_links_entry\"><ul class=\"tp_pub_list\"><li><i class=\"fas fa-globe\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/www.mdpi.com\/1996-1073\/13\/24\/6735\" title=\"https:\/\/www.mdpi.com\/1996-1073\/13\/24\/6735\" target=\"_blank\">https:\/\/www.mdpi.com\/1996-1073\/13\/24\/6735<\/a><\/li><li><i class=\"ai ai-doi\"><\/i><a class=\"tp_pub_list\" href=\"https:\/\/dx.doi.org\/https:\/\/doi.org\/10.3390\/en13246735\" title=\"Follow DOI:https:\/\/doi.org\/10.3390\/en13246735\" target=\"_blank\">doi:https:\/\/doi.org\/10.3390\/en13246735<\/a><\/li><\/ul><\/div><p class=\"tp_close_menu\"><a class=\"tp_close\" onclick=\"teachpress_pub_showhide('80','tp_links')\">Close<\/a><\/p><\/div><\/td><\/tr><\/table><\/div>\n\n\n\n<p><p align=\"justify\">This paper, which is an overview of the innovations in process control presents an insight into the existing models of the internal load motion in tumbling mills.
