B&W supports pulverizers/mills manufactured by CE and others, including: CE/Raymond deep bowl mills. CE shallow bowl mills. Schenck Raymond roller mills.
Bowl is made to rotate at medium speed for proper pulverization of coal. Springs exert necessary pressure on rolls for grinding. Hot air through the mill besides removing coal moisture picks up the lighter particles and takes them through the classifier and drop down the higher size particles for further grinding.
Holmes Coal Pulverizers are bench-type units that perform well in reducing coal or coke from No.4 to No.60 sieve size. Models are available with manual or auger feed. All units have a one-piece balanced rotor and hard coated hammers driven by a single-phase motor with overload protection.
