Power Mills Mill Technology GE Steam Power
Pulverizing solid fuel to powder enables its drying and transport for combustion in large furnace sizes. Fine grinding increases the fuel exposed surface area while simultaneously drying and controlling its distribution. 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 Pulverizer
