American Pulverizer's FCC Series Frozen Crackers are designed to handle a high volume of rain, sleet, snow, or moisture-frozen coal and limestone directly from rail cars or open storage. The ratchet-adjustable breaker plate allows breaking to pre-frozen lump size. Sectionalized cutter discs reduce maintenance and can be removed individually without needing to take out and replace the entire drum.
Wide intake and discharge openings permit dumping frozen coal or limestone directly into wide open-throat hoppers and eliminates wedging and jamming encountered in ordinary hoppers with narrow throats.
Bulldoze or shovel frozen material directly into the hoppers. The cracker prevents jamming and keeps feeding into the plant without interruption, even in the worst weather conditions. The overall height of these machines is less than 45 inches providing easier access for maintenance in close quarters.
Frozen Crackers have a chain driven reduction unit that provides high running torque at a low rpm. They also have a spring-loaded toggle mechanism that allows the breaker plate to open if overload occurs. Stainless steel pins are used to prevent seizing due to corrosion.
FCC roll shafts are forged from heat-treated steel. Tapered roller bearings are high-quality, self-aligning, and grease lubricated.
