pelletiserad

Pelletiserad is a Swedish term that translates to "pelletized" in English. It refers to the process of converting loose material, such as powders, grains, or biomass, into small, dense, uniformly shaped pellets. This process is achieved through a pellet mill, which uses pressure and sometimes heat to compact the material. The binding agent is often inherent to the material itself, like lignin in wood, or can be an added binder.

Pelletizing offers several advantages. It increases the bulk density of the material, making it easier to handle, transport, and store. Pellets also tend to be less dusty than their original form, which is beneficial for both industrial processes and for consumer products. Furthermore, the uniform size and shape of pellets allow for more consistent burning in applications like biomass heating systems, leading to more efficient energy conversion and reduced emissions.

Common materials that are pelletized include animal feed, wood waste for fuel, fertilizers, and certain types of plastic. The specific composition of the material and the desired properties of the final pellets dictate the type of pellet mill and the processing conditions used. The pelletising process is a crucial step in making many raw materials more practical and efficient for various industrial, agricultural, and domestic applications.
