Different biomass materials have different properties: tough (cellulose-rich materials such as dry straw, hay, etc.) and hard (twigs, weeds, etc.). A shredder is used to cut biomass fuels into predetermined sizes based on the user's specific demand, such as fuel preparation for gasification stoves, animal feed processing, material processing for making compost, etc.
There are different types of shredder: those that are multifunctional (cutting right on the field, in the warehouse, etc.). These devices run on electricity or gasoline (depending on demand).
