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

Biomass molding fuel is called BMF in other words. They are briquettes, bars, pellets compressed from farming as well as forestry wastes. The production process of biomass gas includes: basic material collection, crushing, blending, drying out, molding, discharge, air conditioning and packing. The molding process is executed by specialized biomass devices Biomass molding fuel has high warmth worth and also reduced pollutant discharge, so it is an ideal alternative to fossil fuel.



How are biomass fuels made?

Biomass molding describes compressing dry and also crushed farming wastes into portable and also solid briquettes or pellets. As the biomass products consists of high lignin material, it will certainly thaw under high temperature and function as binders that glue the products with each other. In some cases they need to be added with some binders or additives. The biomass molding devices has the procedures of squashing, warm molding as well as shape upkeep.



The compressed biomass fuels are used in home heating cooktop, commercial boiler and power plant. They have the advantages of high thickness, excellent burning efficiency, high home heating effectiveness, low ash deposit, as well as low pollutant discharge. Besides, they are easy to stir up, shop, and transport, with large market developing possibility.



Biomass gas molding tools.

According to various molding innovation, the biomass gas molding tools can be identified into 4 kinds: stamping briquette press, screw squeezing out briquette machine, ring die pellet machine, and flat die pellet machine.



Stamping briquette press

Stamping briquette press make use of the two-way squeeze of reciprocating pistons to mold biomass materials into briquettes. By changing machine a pellet , marking briquette press can produce briquettes of various shapes and sizes. As marking briquette press has brief extrusion time, so the thickness of briquettes is reasonably reduced.



Screw squeezing out briquette press


Screw squeezing out briquette press has the comparable structure as meat grinder. The molding structure includes a screw prop, compression chamber, holes on mold and mildews, as well as a slicer. When the raw materials are fed to the briquette press, the screw propeller press them forward till they go through the holes on the moulds, where they are formed right into round bars. Afterwards, the slicer cut the bars right into particular length.



Ring die pellet machine

The molding component is a ring die with many openings on it, and also 2 or 3 press roller inside the ring die. When the raw products are fed to the compression chamber, the roller press the raw materials outside, as well as press them into the holes on the ring die. When the raw materials travel through the holes and also come out, they come to be strong round pellets. After that slicers cut them short. Ring die pellet machine has huge capacity, suitable for tool and huge wood pellet manufacturing facility.



Apartment die pellet machine

In flat die pellet machine, the roller is set up on an upright shaft as well as hold on to the upside of the flat die. The raw products fall on the level die as well as the roller press them downward. Then they are ejected from the holes on level die and reduced by a slicer. Apartment die pellet machine has smaller dimension as well as low cost, suitable for home use and also small wood pellet manufacturing facility.



Requirement on materials to make molding gas

Tiny dimension and also high density


The greater the thickness as well as fluidity of resources, the greater the production. The ideal dimension of raw materials is under 5mm. chicken pellet making machine is advised to squash the crop straws right into great granules with a timber pulverizer. If you use a knead machine to refine the raw materials, there will certainly be lots of silks, which is tough to feed, as well as the manufacturing is reduced.



Correct water material

The ideal moisture web content of resources need to be 15%-18%. Too expensive or also low water material will both influence the manufacturing and also high quality of biomass fuel. If the wetness content is too high, the raw material will create sliding in between the inner wall and moulds, and also obstruct the mould. If the dampness web content is less than 14%, the raw product will certainly cause severe rubbing to the moulds, and the production is reduced.
