Biomass fuel molding equipment and technology
Biomass fuel molding devices and also innovation
What is biomass molding fuel?
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 gas consists of: raw material collection, squashing, blending, drying out, molding, discharge, air conditioning and packaging. The molding procedure is performed by specialized biomass tools Biomass molding fuel has high warmth value and reduced contaminant discharge, so it is an excellent alternative to nonrenewable fuel source.

Just how are biomass gas made?
Biomass molding refers to pressing dry and smashed farming wastes right into compact and also solid briquettes or pellets. As the biomass materials has high lignin material, it will certainly thaw under high temperature and work as binders that adhesive the materials together. In some cases they need to be added with some binders or ingredients. The biomass molding equipment has the procedures of crushing, hot molding as well as form upkeep.


The compressed biomass gas are used in heating range, industrial central heating boiler and nuclear power plant. They have the advantages of high thickness, great burning performance, high home heating performance, reduced ash deposit, as well as low contaminant exhaust. Besides, they are simple to ignite, store, as well as transport, with big market establishing possibility.

Biomass gas molding equipment.
According to various molding innovation, the biomass fuel molding devices can be categorized right 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 press of reciprocating pistons to mold biomass materials into briquettes. By changing the extrusion mold and mildew, marking briquette press can generate briquettes of various sizes and shapes. As stamping briquette press has brief extrusion time, so the density of briquettes is relatively reduced.

Screw extruding briquette press
Screw squeezing out briquette press has the similar framework as meat mill. The molding structure consists of a screw prop, compression chamber, openings on molds, as well as a slicer. When the raw products are fed to the briquette press, the screw propeller press them forward till they travel through the holes on the moulds, where they are created right into round bars. After that, the slicer reduced the bars into specific length.

Ring die pellet machine
The molding component is a ring die with lots of openings on it, as well as 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 press them into the holes on the ring die. When the raw materials travel through the holes and come out, they come to be strong cylindrical pellets. After that Richi machinery reduced them short. Ring die pellet machine has big ability, appropriate for tool as well as large wood pellet manufacturing facility.

In level die pellet machine, the roller is installed on a vertical shaft and cling to the advantage of the level die. home made pellet mill fall on the flat die as well as the roller press them downward. After that they are ejected from the holes on flat die and reduced by a slicer. Flat die pellet machine has smaller sized size as well as affordable, appropriate for home use and tiny wood pellet manufacturing facility.

Demand on products to make molding gas
Tiny size as well as high thickness
The greater the density and fluidity of raw materials, the higher the manufacturing. The ideal size of basic materials is under 5mm. It is advised to crush the plant straws right into great granules with a wood pulverizer. If you make use of a knead machine to process the raw materials, there will be many silks, which is tough to feed, as well as the production is reduced.

Correct water web content
The ideal wetness material of basic materials ought to be 15%-18%. Expensive or too low water content will both influence the production and also top quality of biomass gas. If the moisture web content is expensive, the raw material will trigger sliding between the inner wall surface and moulds, and even obstruct the mould. If the moisture content is lower than 14%, the raw material will certainly cause severe rubbing to the moulds, and also the production is low.
