In 1886, Loy Satany and Fred Hepworth patented a soil pulverizer, followed by Frederick Meier's patent for a clod crusher in 1892. Throughout the next century, pulverizers diversified and advanced. By the late 1940s and early 1950s, engineers had increased pulverizer speeds, leading to the development of the jet pulverizer in 1954.

All efforts must be taken to prevent coal from accumulating or settling in any of the pulverizer components. Dry coal that is allowed to remain in the pulverizer system can spontaneously ignite. Raw coal to the pulverizer must be uninterrupted and controllable. Precise feeder control and minimal stoppages above and below the feeder are crucial.

Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.
