Biomass molding fuel is called BMF in short. They are briquettes, bars, pellets compressed from agriculture and also forestry wastes. The manufacturing process of biomass fuel includes: raw material collection, crushing, mixing, drying out, molding, discharge, cooling and also packaging. The molding process is carried out by specialized biomass tools Biomass molding fuel has high warm worth as well as low pollutant exhaust, so it is a perfect alternative to fossil fuel.
How are biomass fuels made?
Biomass molding refers to compressing completely dry and also crushed farming wastes right into portable and also strong briquettes or pellets. As the biomass materials includes high lignin content, it will certainly thaw under heat as well as function as binders that adhesive the products with each other. Occasionally they require to be included with some binders or ingredients. The biomass molding devices has the procedures of squashing, warm molding and also form upkeep.
The compressed biomass gas are used in home heating cooktop, industrial boiler and nuclear power plant. They have the advantages of high thickness, excellent burning performance, high heating performance, low ash residue, as well as low contaminant exhaust. Besides, they are easy to fire up, store, as well as transport, with large market creating prospect.
Biomass fuel molding equipment.
According to various molding technology, the biomass gas molding devices can be identified into 4 kinds: marking briquette press, screw extruding briquette machine, ring die pellet machine, as well as flat die pellet machine.
Marking briquette press
Marking briquette press make use of the two-way squeeze of reciprocating pistons to mold and mildew biomass products into briquettes. By changing the extrusion mold and mildew, marking briquette press can produce briquettes of various sizes and shapes. As marking briquette press has short extrusion time, so the density of briquettes is fairly low.
Screw squeezing out briquette press
Screw squeezing out briquette press has the similar structure 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 propeller press them forward till they travel through the holes on the moulds, where they are formed right into round bars. After that, the slicer reduced the bars right into particular size.
Ring die pellet machine
The molding component is a ring die with lots of holes 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 products outside, as well as press them into the holes on the ring die. When the raw products pass through the holes as well as come out, they become solid cylindrical pellets. After that slicers reduced them short. Ring die pellet machine has huge capability, ideal for tool as well as huge timber pellet manufacturing facility.
Flat die pellet machine
In level die pellet machine, the roller is mounted on an upright shaft and also cling to the benefit of the flat die. The raw products fall on the flat die as well as the roller press them downward. Then richi pellet machine are squeezed out from the holes on flat die and reduced by a slicer. Flat die pellet machine has smaller size as well as inexpensive, suitable for house use and also small timber pellet factory.
Demand on products to make molding fuel
Tiny dimension as well as high thickness
The greater the density and fluidity of resources, the higher the production. The ideal dimension of raw materials is under 5mm. It is suggested to crush the plant straws right into great granules with a wood pulverizer. If you use a knead machine to refine the raw materials, there will certainly be lots of silks, which is tough to feed, and the production is low.
Appropriate water content
The ideal dampness material of raw materials must be 15%-18%. Too high or also low tide material will certainly both affect the manufacturing and quality of biomass gas. If fish feed pelletizer is too high, the raw material will create sliding between the internal wall surface as well as moulds, and also block the mould. If the dampness material is less than 14%, the raw product will certainly create severe rubbing to the moulds, as well as the production is low.
