What does pelletizing mean?
Pelletizing is the process of converting finely divided materials into small, compact pellets. The pellets are typically uniform pieces that are easier to store, transport, meter, and feed into machinery than the original powder or loose material. The term is especially common in the manufacture of plastic resins, biomass fuels, animal feed, fertilizer, and other granulated products. Depending on the material and intended use, pelletizing may involve compression, extrusion, agglomeration, or a combination of these methods. It can also refer to the industry as a whole, as when a company describes its pelletizing capacity. The word belongs primarily to manufacturing, agricultural processing, and energy contexts. Although it has a straightforward literal meaning, it forms part of the vocabulary of modern bulk-material handling, where consistency in pellet size and moisture content can affect storage, transport, and the performance of downstream equipment.

Where does pelletizing come from?
Pelletizing derives from pelletize, which combines pellet with the suffix -ize. Pellet comes through Middle English from Old French pellet, a diminutive related to pelte, meaning a skin or hide, ultimately from Latin pellis. The related English words pellicle and pelt also trace to Latin roots concerning skin, although they developed with different meanings and uses.
