Biomass fuel molding devices and modern technology<br>
What is biomass molding fuel?

Biomass molding gas is called BMF basically. They are briquettes, bars, pellets pressed from agriculture as well as forestry wastes. The production process of biomass gas includes: raw material collection, crushing, mixing, drying out, molding, discharge, cooling and packing. The molding procedure is accomplished by specialized biomass devices Biomass molding gas has high heat worth as well as reduced pollutant emission, so it is an excellent replacement for nonrenewable fuel source.



Exactly how are biomass gas made?

Biomass molding describes pressing dry and smashed farming wastes into compact and solid briquettes or pellets. As the biomass products consists of high lignin content, it will thaw under heat as well as work as binders that glue the materials together. Sometimes they need to be added with some binders or ingredients. The biomass molding tools has the processes of crushing, warm molding and also shape upkeep.




The pressed biomass fuels are utilized in home heating cooktop, commercial boiler as well as nuclear power plant. They have the advantages of high thickness, good burning efficiency, high home heating performance, low ash deposit, as well as low pollutant exhaust. Besides, they are easy to fire up, store, as well as transport, with huge market creating possibility.



Biomass gas molding equipment.

According to various molding technology, the biomass fuel molding equipment can be identified into 4 types: marking briquette press, screw extruding briquette machine, ring die pellet machine, and flat die pellet machine.



Marking briquette press


Marking briquette press use the two-way press of reciprocating pistons to mold and mildew biomass products right into briquettes. By replacing the extrusion mold and mildew, stamping briquette press can produce briquettes of various sizes and shapes. As stamping briquette press has brief extrusion time, so the thickness of briquettes is reasonably low.



Screw squeezing out briquette press

Screw squeezing out briquette press has the comparable framework as meat grinder. The molding structure consists of a screw prop, compression chamber, openings on mold and mildews, and also a slicer. When the raw materials are fed to the briquette press, the screw prop press them ahead until they go through the holes on the moulds, where they are formed right into round bars. After that, the slicer reduced the bars right into certain size.



Ring die pellet machine

The molding part is a ring die with lots of holes on it, as well as 2 or 3 press roller inside the ring die. When feed machine for poultry are fed to the compression chamber, the roller press the raw products outward, as well as squeeze them right into the holes on the ring die. When the raw materials go through the holes and also appear, they come to be strong round pellets. After that slicers reduced them short. Ring die pellet machine has large capacity, appropriate for tool as well as big wood pellet manufacturing facility.



Flat 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 materials fall on the flat die and also the roller press them downward. Then they are squeezed out from the holes on flat die as well as cut by a slicer. Apartment die pellet machine has smaller size as well as inexpensive, ideal for house use as well as little timber pellet factory.



Requirement on products to make molding gas

Little dimension and high density

The higher the thickness and fluidness of resources, the higher the manufacturing. The appropriate size of basic materials is under 5mm. It is suggested to crush the crop straws into great granules with a timber pulverizer. If you make use of a knead machine to refine the raw products, there will be many silks, which is hard to feed, as well as the manufacturing is low.



Correct water content

The suitable wetness web content of resources must be 15%-18%. pellet mill press or too low water web content will certainly both affect the production as well as high quality of biomass fuel. If the dampness content is too high, the raw product will certainly cause sliding in between the inner wall surface as well as moulds, and also obstruct the mould. If the moisture content is less than 14%, the raw product will create severe rubbing to the moulds, as well as the production is low.
