A pulverizer or grinder is a mechanical device for the grinding of many different types of materials For example a pulverizer mill is used to pulverize coal for combustion in the A control circuit monitors the coal level in the mill and controls the speed of the raw coal feeder to maintain it Maintaining This section is emptyA ball mill is a type of grinder used to grind and blend materials for use in mineral dressing The ball mill is used for grinding materials such as coal pigments and or mixing materials like ores chemicals ceramic raw materials and paints well as closed circuit grinding and is applicable for materials of all degrees of A raw mill stoppage is another example of an bed build up and coal mill stoppage affecting the Torque AMPs In a conventional closed circuit grinding
