Biomass fuel molding tools as well as technology<br>
What is biomass molding fuel?

Biomass molding gas is called BMF in other words. They are briquettes, bars, pellets pressed from farming and also forestry wastes. The manufacturing process of biomass gas includes: resources collection, crushing, blending, drying out, molding, discharge, air conditioning and also packaging. The molding process is carried out by specialized biomass tools Biomass molding gas has high heat worth and also reduced contaminant discharge, so it is an optimal substitute for fossil fuel.



Just how are biomass gas made?

Biomass molding describes pressing completely dry and also smashed farming wastes right into compact as well as strong briquettes or pellets. As the biomass products includes high lignin material, it will certainly melt under heat as well as act as binders that glue the products together. Sometimes they need to be added with some binders or additives. The biomass molding tools has the processes of crushing, hot molding as well as shape maintenance.



The pressed biomass fuels are made use of in home heating range, commercial boiler as well as nuclear power plant. They have the advantages of high density, good burning performance, high heating efficiency, reduced ash deposit, as well as reduced pollutant emission. Besides, they are easy to ignite, store, and transport, with big market developing possibility.




Biomass gas molding tools.

According to different molding innovation, the biomass gas molding tools can be identified into 4 kinds: marking briquette press, screw squeezing out briquette machine, ring die pellet machine, and also level die pellet machine.



Stamping briquette press

Marking briquette press use the two-way capture of reciprocating pistons to mold and mildew biomass products right into briquettes. By changing the extrusion mold, marking briquette press can produce briquettes of different sizes and shapes. As marking briquette press has brief extrusion time, so the thickness of briquettes is fairly reduced.



Screw extruding briquette press

Screw extruding briquette press has the similar framework as meat mill. The molding framework consists of a screw prop, compression chamber, openings on mold and mildews, and also a slicer. When the raw products are fed to the briquette press, the screw propeller press them forward till they pass through the holes on the moulds, where they are created into cylindrical bars. After that, the slicer cut the bars into particular length.



Ring die pellet machine

The molding part 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 materials external, and also press them right into the holes on the ring die. When the raw products go through the holes and appear, they come to be strong cylindrical pellets. After that slicers cut them short. Ring die pellet machine has huge capacity, suitable for tool as well as large timber pellet factory.



Flat die pellet machine

In level die pellet machine, the roller is mounted on an upright shaft and hold on to the benefit of the level die. The raw materials fall on the flat die as well as the roller press them downward. After that they are squeezed out from the holes on level die as well as reduced by a slicer. Apartment die pellet machine has smaller dimension as well as low cost, ideal for house use and small wood pellet manufacturing facility.



Requirement on materials to make molding gas

Little size and also high density

The greater the density and also fluidness of basic materials, the higher the production. The ideal dimension of raw materials is under 5mm. It is advised to crush the plant straws into great granules with a timber pulverizer. If you use a knead machine to refine the raw products, there will certainly be numerous silks, which is tough to feed, and the manufacturing is low.



Proper water content


The suitable dampness material of basic materials should be 15%-18%. Too expensive or too low water content will both influence the manufacturing and top quality of biomass gas. If hdpe pelletizing machine is too expensive, the raw product will cause slipping in between the inner wall surface and moulds, and also block the mould. If richi pellet is less than 14%, the raw material will create serious friction to the moulds, and the production is reduced.
