From our original E/EL ball-and-race type pulverizers for lower capacity applications, to the latest B&W Roll Wheel™ pulverizer capable of grinding up to 230,000 pounds of coal per hour (104,300 kg/hr), we set the standard for high availability, reliability and low maintenance.
Ring-Roll (Bowl-Mill) and Ball-Race Mills comprise the majority of coal pulverizers currently in service at power generating facilities. In this design the grinding rolls are stationary, while the ring (or bowl, as it is sometimes called) is rotated by a worm gear drive.
GE’s PV-PRO mill upgrade system uses a patented process for better control of coal fineness and reduced pulverizer wear for extended operations. Up to 6x life extension HCX2* ceramic inserted grinding elements significantly extend operating time between overhauls. Up to 3.5x life extension over high chrome and high chrome overlay.
B&W's pulverizers, found at power stations throughout the world. From our original E/EL ball-and-race type pulverizers for lower capacity applications, to the latest B&W Roll Wheel™ pulverizer capable of grinding up to 230,000 pounds of coal per hour
The four most common types of coal pulverizers are: Ball-Tube Mills. This type of mill consists of a rotating tube filled with cast alloy balls. Coal is introduced through two hollow trunnions on each side of the tube. As the tube rotates, the balls tumble onto the coal, crushing and pulverizing it. Impact Mills. Grinding Action is carried out by a series of hinged or fixed hammers revolving

02/06/2017 Crushers, grinding mills and pulverizers are types of grinding equipment used to transform or reduce a coarse material such as stone, coal, or slag into a smaller, finer material. Grinding equipment can be classified into to two basic types, crushers and grinders. Industrial crushers are the first level of size reducer; further granularization occurs in grinding mills or pulverizers.
Coal pulverizer design and operation is an important element integral to the long term success of Low NOx combustion systems. The increased use of Low NOx burners in the past 10 years has instigated a need for further development of coal pulverizer technology in an effort to ensure efficient operation of a power boiler for minimizing gaseous emissions (NOx, CO, HC) and unburned carbon in fly
