To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions.
Processing raw coal into pulverized coal involves several intricate steps that ultimately convert raw coal into fine powder primed for energy generation. However, it is crucial to handle pulverized coal …
In the late 19th century, American entrepreneurs and engineers recognized the potential of pulverizers beyond coal applications, focusing on agricultural uses.
