Pulverizer Wikipedia

网页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 steam-generating or pressurised rams. The material to be pulverized is introduced into the center or side of the pulverizer (depending on the design).
