In 1824, French physicist Sadi Carnot advanced the coal pulverizer's significance by designing an engine based on the thermodynamic cycle, which utilized pulverized coal. In the late 19th century, American entrepreneurs and engineers recognized the potential of pulverizers beyond coal applications, focusing on agricultural uses.

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.

Coal is crushed to desired fineness between spheres or cylindrical rollers. After that, air from the boiler is heated to around 330°C (650°F). The raw coal is then fed into the pulverizer where it is ground into fine coal …
