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


Biomass molding fuel is called BMF in short. They are briquettes, bars, pellets compressed from farming and forestry wastes. The production procedure of biomass gas consists of: basic material collection, squashing, blending, drying, molding, discharge, cooling and packaging. The molding procedure is accomplished by specialized biomass tools Biomass molding fuel has high warmth value and also reduced pollutant discharge, so it is an ideal replacement for fossil fuel.



How are biomass fuels made?

Biomass molding refers to pressing completely dry as well as crushed farming wastes into small and also strong briquettes or pellets. As small chicken feed pellet machine has high lignin content, it will certainly thaw under high temperature as well as function as binders that adhesive the products together. Occasionally they require to be added with some binders or additives. The biomass molding devices has the procedures of crushing, hot molding as well as form upkeep.



The pressed biomass fuels are utilized in heating oven, commercial central heating boiler and nuclear power plant. They have the advantages of high thickness, good burning efficiency, high heating effectiveness, reduced ash residue, as well as reduced pollutant discharge. Besides, they are simple to fire up, shop, and also transport, with huge market creating possibility.



Biomass fuel molding equipment.

According to different molding innovation, the biomass fuel molding devices can be classified right into 4 types: stamping briquette press, screw extruding 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 and mildew biomass products into briquettes. By changing the extrusion mold and mildew, stamping briquette press can create briquettes of different shapes and sizes. As marking briquette press has brief extrusion time, so the density of briquettes is relatively reduced.



Screw squeezing out briquette press

Screw extruding briquette press has the comparable structure as meat grinder. The molding framework includes a screw prop, 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 pass through the holes on the moulds, where they are created into round bars. After that, the slicer cut the bars into specific size.



Ring die pellet machine

The molding part is a ring die with numerous holes 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 products external, and press them right into the holes on the ring die. When floating fish feed making machine pass through the holes and appear, they become strong cylindrical pellets. Then slicers reduced them short. Ring die pellet machine has huge capability, suitable for medium and also huge timber pellet manufacturing facility.



Apartment die pellet machine

In flat die pellet machine, the roller is mounted on an upright shaft and hold on to the advantage of the level die. The raw materials fall on the level die as well as the roller press them downward. Then they are ejected from the holes on level die and also reduced by a slicer. Flat die pellet machine has smaller dimension and inexpensive, ideal for residence use as well as tiny wood pellet factory.



Requirement on materials to make molding fuel

Tiny size as well as high thickness

The greater the thickness and also fluidity of raw materials, the higher the production. The suitable size of resources is under 5mm. It is recommended to squash the plant straws into fine granules with a wood pulverizer. If you make use of a knead machine to refine the raw products, there will be numerous silks, which is tough to feed, and the production is low.



Appropriate water web content


The appropriate wetness material of basic materials must be 15%-18%. Too expensive or as well low tide content will certainly both affect the production as well as quality of biomass fuel. If the moisture content is too expensive, the raw product will certainly trigger sliding between the inner wall as well as moulds, and also even obstruct the mould. If the moisture content is less than 14%, the raw product will cause severe rubbing to the moulds, as well as the manufacturing is reduced.
