Description

A molding device for biomass fuel production

technical field

The utility model relates to the technical field of biomass production equipment, in particular to a molding device for biomass fuel production.

Background technique

Biomass fuel refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste, which is mainly different from fossil fuels. The application of biomass fuel is actually mainly biomass briquette fuel, which is a new type of clean fuel that uses agricultural and forestry waste as raw materials and undergoes crushing, mixing, extrusion, drying and other processes to make various moldings and can be directly burned.

The existing granule molding machines generally have the disadvantages of unstable performance and low productivity, and the existing granule machine, when the filler is too much and too thick, will overload the machine, commonly known as the phenomenon of "jamming".
