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

Biomass molding gas is called BMF in short. They are briquettes, bars, pellets pressed from agriculture and also forestry wastes. The production procedure of biomass fuel consists of: resources collection, crushing, blending, drying out, molding, discharge, cooling and packaging. The molding process is performed by specialized biomass tools Biomass molding fuel has high heat worth and reduced contaminant emission, so it is a suitable substitute for fossil fuel.



How are biomass gas made?

Biomass molding refers to compressing dry and also crushed farming wastes right into small as well as strong briquettes or pellets. As the biomass materials consists of high lignin content, it will thaw under heat as well as act as binders that glue the materials together. Sometimes straw pelletizer require to be added with some binders or additives. The biomass molding devices has the procedures of squashing, warm molding and also form upkeep.



The pressed biomass gas are used in home heating oven, commercial central heating boiler and also nuclear power plant. They have the advantages of high density, great burning performance, high home heating efficiency, reduced ash deposit, and also reduced pollutant exhaust. Besides, they are very easy to spark, store, as well as transport, with huge market creating prospect.



Biomass fuel molding equipment.

According to various molding modern technology, the biomass gas molding devices can be identified into 4 kinds: marking briquette press, screw extruding briquette machine, ring die pellet machine, and also flat die pellet machine.




Stamping briquette press

Stamping briquette press utilize the two-way squeeze of reciprocating pistons to mold biomass materials right into briquettes. By replacing the extrusion mold, marking briquette press can produce briquettes of different sizes and shapes. As stamping briquette press has brief extrusion time, so the thickness of briquettes is relatively low.




Screw extruding briquette press

Screw extruding briquette press has the similar structure as meat mill. The molding framework includes a screw propeller, 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 forward until they go through the holes on the moulds, where they are created right into round bars. After that, the slicer cut benches right into certain size.



Ring die pellet machine

The molding component is a ring die with several 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 exterior, and press them into the holes on the ring die. When the raw products travel through the holes and appear, they become solid round pellets. Then slicers reduced them short. Ring die pellet machine has large capability, appropriate for medium and also large timber pellet factory.



Flat die pellet machine

In flat die pellet machine, the roller is mounted on an upright shaft and cling to the advantage of the level die. The raw products fall on the level die and the roller press them downward. Then electric wood pellet mill are ejected from the holes on flat die and also cut by a slicer. Flat die pellet machine has smaller sized size as well as low cost, suitable for house use and tiny timber pellet manufacturing facility.



Demand on materials to make molding gas

Tiny size and also high thickness

The higher the density and fluidity of resources, the higher the manufacturing. The suitable dimension of raw materials is under 5mm. It is suggested to crush the crop straws right into great granules with a wood pulverizer. If you use a knead machine to refine the raw products, there will certainly be lots of silks, which is hard to feed, and the manufacturing is reduced.



Appropriate water content

The suitable dampness material of resources ought to be 15%-18%. hen feed making machine or as well low tide content will certainly both affect the manufacturing and quality of biomass fuel. If the moisture material is too expensive, the raw product will cause slipping in between the internal wall as well as moulds, as well as also block the mould. If the dampness web content is lower than 14%, the raw material will create severe friction to the moulds, and also the production is reduced.
