The Pennsylvania Coalpactor® is experiencing a strong surge of interest within the power industry. Though originally designed to handle coking coals, today it plays a key role for power plants with fluidized bed boilers. This is because it produces the sizes required for fluidized bed applications with greater efficiency than other types of coal crushers. In terms of output size, the Coalpactor fills the gap between Pennsylvania Granulators (ring hammermills) used to obtain ½” and larger sizes, and Pennsylvania Reversible Hammermills used for top sizes as small as 3/16”.

Similar to an impactor, the Coalpactor has breaker plates that are fully adjustable from outside of the frame in order to vary the output size. The machine offers lower cost-per-ton-crushed and lower horse power demand than other crushers. Rated capacity is maintained even when the coal is wet, or when crushing difficult materials like petroleum coke.

The design of the Coalpactor includes a crushing chamber which is formed by a pair of curved breaker plate assemblies on opposite sides of the rotor assembly. This assembly rotor is reversible, enabling both hammer faces to wear at a uniform rate. This extends hammer life and reduces maintenance. All internal parts are readily accessible for servicing.
