RDF fuel briquette press machine can compress agricultural and forestry wastes into briquettes by high-speed compression.It adopts new compression mode and the variable vertical ring die structure is produced in a flat ring mode.The principle of self-rotating centrifugal force is used to evenly distribute the raw materials into all the forming molds.The machine is consisted of conveyor system,forming system,outlet,heating and control cabinet.The briquette can increase the proportion of biomass, extend the burning time and facilitate storage and transportation.
