Biomass gas molding tools as well as modern technology<br>
What is biomass molding fuel?

Biomass molding gas is called BMF in short. Richi machine are briquettes, bars, pellets pressed from agriculture and forestry wastes. richi machinery manufacturing process of biomass gas consists of: raw material collection, squashing, mixing, drying, molding, discharge, air conditioning and packaging. The molding procedure is executed by specialized biomass tools Biomass molding fuel has high heat worth and reduced pollutant emission, so it is a suitable replacement for fossil fuel.



Exactly how are biomass fuels made?

Biomass molding refers to pressing dry and crushed agriculture wastes right into portable and strong briquettes or pellets. As the biomass materials contains high lignin content, it will certainly thaw under high temperature and also serve as binders that adhesive the products together. Occasionally they require to be added with some binders or additives. The biomass molding devices has the processes of crushing, warm molding and also shape upkeep.



The compressed biomass fuels are utilized in home heating cooktop, commercial central heating boiler and nuclear power plant. They have the advantages of high density, good burning efficiency, high heating effectiveness, low ash deposit, and reduced contaminant emission. Besides, they are easy to spark, store, and transport, with huge market creating possibility.




Biomass fuel molding tools.

According to different molding technology, the biomass gas molding tools can be identified into 4 types: marking briquette press, screw squeezing out briquette machine, ring die pellet machine, and flat die pellet machine.




Stamping briquette press

Stamping briquette press make use of the two-way squeeze of reciprocating pistons to mold biomass materials right into briquettes. By changing the extrusion mold and mildew, stamping briquette press can generate briquettes of different sizes and shapes. As stamping briquette press has brief extrusion time, so the density of briquettes is relatively low.



Screw extruding briquette press

Screw extruding briquette press has the comparable framework as meat mill. The molding structure consists of a screw propeller, compression chamber, openings on molds, and 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 formed into round bars. After that, the slicer cut benches into specific size.



Ring die pellet machine

The molding part is a ring die with numerous 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, as well as squeeze them into the holes on the ring die. When the raw materials travel through the holes and come out, they come to be solid cylindrical pellets. After that slicers reduced them short. Ring die pellet machine has huge capability, ideal for medium and huge wood pellet manufacturing facility.



Flat die pellet machine

In flat die pellet machine, the roller is mounted on an upright shaft and also hold on to the upside of the level die. The raw materials fall on the level die and the roller press them downward. After that they are squeezed out from the holes on flat die and reduced by a slicer. Flat die pellet machine has smaller sized size and also low cost, appropriate for residence use and tiny timber pellet manufacturing facility.



Demand on materials to make molding gas

Tiny dimension as well as high density

The greater the density and also fluidity of resources, the greater the production. The appropriate size of resources is under 5mm. It is advised to squash the plant straws into fine granules with a timber pulverizer. If you utilize a knead machine to refine the raw materials, there will be many silks, which is difficult to feed, as well as the manufacturing is low.



Proper water content

The suitable wetness material of basic materials should be 15%-18%. Expensive or also low water material will both affect the production as well as quality of biomass fuel. If the wetness web content is expensive, the raw material will create slipping in between the internal wall and also moulds, and even obstruct the mould. If the wetness web content is lower than 14%, the raw material will create severe rubbing to the moulds, and the manufacturing is reduced.
