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

Biomass molding fuel is called BMF in short. They are briquettes, bars, pellets compressed from agriculture and also forestry wastes. The production procedure of biomass gas includes: basic material collection, crushing, blending, drying out, molding, discharge, cooling as well as packing. The molding process is carried out by specialized biomass tools Biomass molding fuel has high heat value and also low toxin exhaust, so it is an optimal replacement for nonrenewable fuel source.



Exactly how are biomass fuels made?


Biomass molding refers to pressing dry as well as smashed farming wastes into portable and also strong briquettes or pellets. As the biomass materials includes high lignin material, it will melt under heat and also serve as binders that glue the materials with each other. Sometimes they need to be included with some binders or ingredients. The biomass molding tools has the procedures of crushing, hot molding and form upkeep.



The pressed biomass fuels are used in heating stove, commercial boiler as well as nuclear power plant. They have the advantages of high density, great burning performance, high heating performance, low ash deposit, and also low toxin exhaust. Besides, they are easy to stir up, store, and also transport, with big market creating possibility.



Biomass gas molding devices.

According to various molding innovation, the biomass fuel molding tools can be categorized into 4 types: stamping briquette press, screw squeezing out briquette machine, ring die pellet machine, and also flat die pellet machine.




Stamping briquette press

Stamping briquette press make use of the two-way press of reciprocating pistons to mold and mildew biomass materials right into briquettes. By changing the extrusion mold, marking briquette press can create briquettes of different sizes and shapes. As marking briquette press has short extrusion time, so the density of briquettes is relatively low.



Screw extruding briquette press

Screw squeezing out briquette press has the comparable structure as meat mill. The molding framework includes a screw prop, compression chamber, openings on molds, and a slicer. When the raw materials are fed to the briquette press, the screw prop press them forward until they pass through the holes on the moulds, where they are formed right into round bars. After that, the slicer cut benches right into particular size.



Ring die pellet machine

The molding component is a ring die with many holes on it, as well as 2 or 3 press roller inside the ring die. When Richi machine are fed to the compression chamber, the roller press the raw materials exterior, and squeeze them into the holes on the ring die. When the raw products go through the holes and come out, they come to be strong cylindrical pellets. Then slicers reduced them short. Ring die pellet machine has big capacity, suitable for medium and also huge timber pellet factory.



Flat die pellet machine

In level die pellet machine, the roller is installed on a vertical shaft and cling to the advantage of the level die. The raw products fall on the level die as well as the roller press them downward. Then they are squeezed out from the holes on level die and also cut by a slicer. Richi machine has smaller dimension as well as inexpensive, ideal for house use and also little timber pellet factory.



Demand on materials to make molding fuel

Tiny size and also high density

The higher the density and also fluidness of resources, the higher the manufacturing. The appropriate size of basic materials is under 5mm. It is recommended to squash the plant straws into great granules with a wood pulverizer. If you make use of a knead machine to refine the raw products, there will certainly be lots of silks, which is tough to feed, and the production is reduced.



Correct water content

The ideal moisture web content of resources need to be 15%-18%. Too high or also low water content will both affect the production and also top quality of biomass fuel. If the moisture material is too expensive, the raw material will certainly trigger sliding in between the internal wall surface as well as moulds, and even block the mould. If the moisture material is less than 14%, the raw material will trigger severe friction to the moulds, as well as the manufacturing is reduced.
