Biomass fuel molding equipment and technology
Biomass fuel molding tools and technology
What is biomass molding fuel?
Biomass molding gas is called BMF simply put. They are briquettes, bars, pellets compressed from agriculture and forestry wastes. The manufacturing procedure of biomass gas consists of: basic material collection, crushing, mixing, drying, molding, discharge, cooling as well as packaging. The molding process is accomplished by specialized biomass devices Biomass molding fuel has high warm worth and reduced contaminant emission, so it is a suitable replacement for fossil fuel.

Just how are biomass fuels made?
Biomass molding refers to pressing completely dry and smashed farming wastes into compact as well as strong briquettes or pellets. As the biomass materials contains high lignin web content, it will certainly thaw under heat as well as function as binders that adhesive the materials together. In some cases they require to be included with some binders or additives. The biomass molding equipment has the processes of crushing, warm molding and also form maintenance.

The pressed biomass gas are used in heating stove, industrial central heating boiler and nuclear power plant. They have the advantages of high density, great burning performance, high home heating efficiency, low ash deposit, and also low pollutant exhaust. Besides, they are easy to stir up, shop, as well as transportation, with big market developing possibility.

Biomass gas molding devices.
According to various molding modern technology, the biomass gas molding tools can be classified right into 4 kinds: stamping briquette press, screw extruding briquette machine, ring die pellet machine, as well as flat die pellet machine.

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

Screw extruding briquette press

Screw squeezing out briquette press has the comparable structure as meat grinder. The molding framework includes a screw propeller, compression chamber, holes on mold and mildews, as well as a slicer. When the raw products are fed to the briquette press, the screw prop press them forward until they pass through the holes on the moulds, where they are developed right into round bars. After that, the slicer reduced the bars right into certain length.

Ring die pellet machine
The molding component is a ring die with many holes on it, and 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 external, as well as squeeze them into the holes on the ring die. When the raw products pass through the holes as well as come out, they end up being solid round pellets. After that slicers cut them short. Ring die pellet machine has big capability, ideal for tool and big wood pellet factory.

fish pellet mill

In flat die pellet machine, the roller is mounted on an upright shaft and hold on to the advantage of the flat die. The raw materials fall on the level die and also the roller press them downward. Then they are squeezed out from the holes on level die and cut by a slicer. Apartment die pellet machine has smaller dimension and also low cost, suitable for house use and also little timber pellet factory.

Demand on materials to make molding fuel
Small size as well as high density
The higher the density as well as fluidness of basic materials, the greater the production. The appropriate dimension of raw materials is under 5mm. It is recommended to squash the plant straws right into fine granules with a timber pulverizer. If you utilize a knead machine to process the raw materials, there will be several silks, which is hard to feed, and the manufacturing is reduced.

Correct water material
The suitable moisture web content of basic materials ought to be 15%-18%. Expensive or also low tide material will both influence the manufacturing and also quality of biomass fuel. If the moisture content is too high, the raw material will certainly cause sliding in between the inner wall surface and moulds, as well as even block the mould. If the moisture material is lower than 14%, the raw material will certainly trigger severe rubbing to the moulds, and the production is reduced.
