Biomass fuel molding devices as well as innovation<br>
What is biomass molding gas?

Biomass molding gas is called BMF basically. They are briquettes, bars, pellets pressed from farming as well as forestry wastes. The production process of biomass gas includes: basic material collection, crushing, mixing, drying, molding, discharge, cooling and packaging. The molding procedure is carried out by specialized biomass tools Biomass molding gas has high heat value and low toxin exhaust, so it is an optimal alternative to fossil fuel.




Just how are biomass fuels made?

Biomass molding describes compressing dry as well as smashed agriculture wastes right into small and strong briquettes or pellets. As richi pellet machine consists of high lignin material, it will melt under heat and serve as binders that glue the materials together. Often they require to be included with some binders or additives. The biomass molding equipment has the procedures of squashing, warm molding and shape maintenance.



The compressed biomass fuels are utilized in home heating cooktop, industrial boiler and nuclear power plant. They have the advantages of high thickness, excellent burning performance, high heating effectiveness, reduced ash deposit, and low contaminant exhaust. Besides, they are simple to spark, store, as well as transport, with huge market creating possibility.



Biomass fuel molding devices.

According to different molding innovation, the biomass fuel molding devices can be classified right into 4 types: stamping briquette press, screw squeezing out briquette machine, ring die pellet machine, as well as flat die pellet machine.



Stamping briquette press

Marking briquette press utilize the two-way capture of reciprocating pistons to mold biomass materials into briquettes. By replacing the extrusion mold, stamping briquette press can create briquettes of different sizes and shapes. As marking briquette press has brief extrusion time, so the density of briquettes is reasonably reduced.



Screw squeezing out briquette press

Screw extruding briquette press has the similar framework as meat grinder. The molding structure consists of a screw propeller, compression chamber, holes on molds, and a slicer. When the raw materials are fed to the briquette press, the screw propeller press them forward up until they pass through the holes on the moulds, where they are formed right into round bars. Afterwards, the slicer cut benches into specific size.



Ring die pellet machine

The molding component is a ring die with many openings on it, as well as 2 or 3 press roller inside the ring die. When the raw materials are fed to the compression chamber, the roller press the raw products external, and also press them into the holes on the ring die. When the raw materials travel through the holes as well as come out, they become strong round pellets. Then slicers cut them short. Ring die pellet machine has large ability, appropriate for tool and big timber pellet factory.



Apartment die pellet machine

In level die pellet machine, the roller is set up on an upright shaft and cling to the upside of the level die. The raw materials fall on the level die and also the roller press them downward. Then shrimp feed machine are squeezed out from the holes on level die and cut by a slicer. Flat die pellet machine has smaller sized dimension as well as affordable, ideal for house use and little timber pellet manufacturing facility.



Need on materials to make molding fuel

Little dimension and high density

The higher the density and fluidness of resources, the greater the production. The suitable size of raw materials is under 5mm. It is advised to squash the crop straws right into great granules with a wood pulverizer. If you make use of a knead machine to refine the raw products, there will be lots of silks, which is difficult to feed, and the production is low.




Appropriate water content

The suitable wetness content of raw materials ought to be 15%-18%. Expensive or as well low water web content will certainly both affect the production and high quality of biomass gas. If the dampness content is too high, the raw product will certainly create slipping in between the inner wall and also moulds, as well as also block the mould. If the wetness content is less than 14%, the raw product will cause severe rubbing to the moulds, and also the manufacturing is reduced.
