Coal Pulverizer. A coal pulverizer is a mechanical device used to grind coal into fine powder for combustion in a furnace or boiler. It is an essential piece of equipment in power generation plants, where it is used to pulverize coal and feed it into the furnace to produce steam, which is then used to generate electricity.
At the heart of fuel efficiency in batch type heat treatment plants, the coal pulverizer is a critical component. We also offer energy efficient technology.
optimal primary air distribution, permitting pulverizer operation at recommended primary air-to-fuel ratios. As a result, the rotating throat reduces coal spillage that can occur with poor air distribution and high pressure drop that occurs when operating at higher than recommended primary air-to-coal ratios.

Coal feeds onto a steel rotating table. Tapered, cylindrical, or spherical rollers on top of the table, under spring pressure, exert force on the coal particles on the table. When the table rotates, the coal passes between the rollers and the table and gets ground due to attrition. The hot air under pressure carries this ground coal upwards.
Metered hot air for drying and coal transport enters the base housing and flows upward through a stationary swirl ring having multiple sloped nozzles surrounding the rotating …
Raw coal produces agglomerates from the pulverized coal and reduces the capacity of the bowl mills. Drying is carried out by injecting hot air into the mills while grinding. The temperature of the air is dependent on the moisture content in the coal and usually varies between 65 to 80°C. 1.4 Pulverized Coal Fineness
In Part I of three parts, we'll examine the essentials of pulverizer capacity, what should be done after a coal pulverizer fire or other incident, and how to tune up pulverizer performance.

Single Pass Air System: With a single pass air system, air is drawn into the mill base, travels through the classifier, bag filter and fan and is then vented out to atmosphere. In addition to being dust free, the air swept grinding zone prevents over-grinding by the air stream lifting the particles of certain sizes out of the grinding zone.
