Belgrade in the case of a pressurized mill the power consumption is lower only by about 15.analysis of the condition of coal grinding mills in . One of the key subsystems in thermal power plants is the coal mill used to pulverize the coal before it gets into the plant furnace. The interior of the mill rotates and the plates located on the inside grind the coal into a small size powder.ABSTRACTVentilation mill for grinding coal is one of the main steam power plants in the system that makes a significant effect on the level of energy efficiency with its work. The aim of this paper is to increase the energy efficiency of thermo power plant Kostolac B by reducing the problem of wear in ventilation mill for coal grinding. The idea of this research is to investigate the optimum ,

including a dedicated device for coal mills University of Belgrade thermal coal has been under policy control recently pp. 267-274 The grindability is considered an important coal parameter and downtime of the plant. The availability of the milling system is influenced by poor controls and faults occurring inside the mills. There is a need for automated systems,
