Coal Pulverizers Market: Global Industry Trend

Coal Pulverizer are used for crushing coal pieces into very fine required particle size in range of micrometers for feeding boilers and ensure minimal energy wastage. The Coal Pulverizer firstly grind coal into a fine powder, followed by drying and classification that plays key role to segregate fine particles of the crushed coal and further send them to the boiler.
