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

Biomass molding fuel is called BMF basically. They are briquettes, bars, pellets compressed from farming and also forestry wastes. The manufacturing process of biomass fuel includes: basic material collection, squashing, mixing, drying out, molding, discharge, cooling and packing. The molding process is carried out by specialized biomass tools Biomass molding fuel has high warmth value and also reduced pollutant exhaust, so it is an excellent alternative to nonrenewable fuel source.




Exactly how are biomass gas made?

Biomass molding refers to compressing completely dry as well as smashed farming wastes right into compact and strong briquettes or pellets. As the biomass products consists of high lignin content, it will thaw under high temperature and also serve as binders that glue the products with each other. Sometimes they need to be added with some binders or additives. The biomass molding devices has the processes of squashing, warm molding and shape maintenance.



The compressed biomass fuels are used in heating stove, commercial boiler as well as power plant. They have the advantages of high density, excellent burning efficiency, high heating performance, low ash residue, and low toxin emission. Besides, they are easy to spark, store, and transportation, with big market establishing possibility.



Biomass fuel molding devices.

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




Stamping briquette press

Stamping briquette press utilize the two-way squeeze of reciprocating pistons to mold biomass products right into briquettes. By changing the extrusion mold and mildew, stamping briquette press can generate briquettes of various shapes and sizes. As marking briquette press has short extrusion time, so the thickness of briquettes is relatively reduced.



Screw extruding briquette press

Screw squeezing out briquette press has the comparable framework as meat grinder. The molding structure includes a screw prop, compression chamber, holes on molds, as well as a slicer. When the raw materials are fed to the briquette press, the screw prop press them ahead until they pass through the holes on the moulds, where they are created into cylindrical bars. Afterwards, the slicer cut the bars into specific length.



Ring die pellet machine

The molding component is a ring die with numerous 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 products outside, and squeeze them into the holes on the ring die. When the raw materials pass through the holes and also appear, they end up being solid cylindrical pellets. Then slicers cut them short. Ring complete pellet mill has large ability, suitable for medium and huge wood pellet factory.



Apartment die pellet machine

In level die pellet machine, the roller is set up on an upright shaft and hold on to the advantage of the level die. The raw products fall on the flat die and the roller press them downward. After that they are squeezed out from the holes on level die and cut by a slicer. Apartment die pellet machine has smaller dimension as well as low cost, suitable for home use and tiny wood pellet manufacturing facility.



Demand on products to make molding fuel

Little size and high density

The greater the thickness and also fluidity of basic materials, the higher the manufacturing. The appropriate dimension of resources is under 5mm. It is suggested to crush the plant straws right into great granules with a wood pulverizer. If you utilize a knead machine to process the raw materials, there will certainly be several silks, which is tough to feed, as well as the production is reduced.



Appropriate water content

The suitable moisture content of resources must be 15%-18%. Too expensive or too low water material will certainly both affect the manufacturing as well as quality of biomass gas. If the moisture content is expensive, the raw material will certainly cause slipping in between the inner wall surface and also moulds, as well as also block the mould. If the dampness material is less than 14%, the raw product will certainly cause extreme rubbing to the moulds, and the manufacturing is low.
