Factory price BEST home screw extruder biomass wood sawdust charcoal mini briquetting press project small briquette machine

 Briquetting press machine is a project that turns agricultural and forestry wastes into biomass briquettes. The best home screw mini briquetting press machine  is composed of different steps of equipments, such as wood chipper, crusher/hammer mill, dryer, small briquette machine, cooler, packager and the conveyor connecting each step. If necessary, it needs carbonization device like carbonization furnace to carbonize the wood briquettes into charcoal.

Raw material used in briquetting press machineRaw material including plant straw, manure peper, grain husk, peanut shell, cotton rod, wood chip, sawdust, branch, bark, bamboo powder, wood timbering, forest residual and household refuse, etc. It could be made into briquettes through briquetting press machine after being crushed. Keep the moisture of the feedstock at around 15% and  size less than 20mm (peanut shell needs no crush, while the wood chips should be crushed into 3-5mm) when using the biomass charcoal mini briquetting press machine.

Briquetting press machine  working principle

Briquetting is a process that biomass is compressed under high pressure and high temperature. The briquetting press machine uses a large screw to grind the biomass into briquettes that are of uniform composition.
The self bonding of biomass to form a briquette involves the thermo-plastic flow of the biomass. The lignin content that occurs naturally in biomass is liberated under high pressure and temperature. Lignin serves as the glue in the briquetting process machine, thus binding, compressing the biomass to form into high density briquettes.
During this process, no binder needs to be used. So the output briquette is a type of clean and green fuel that is ideal for use in furnaces, boilers and open fires. The density of the briquettes produced by mini briquetting press machine is 1300kg/CBM.

Characteristics of briquetting press machine

1. Screw briquetting press machine can produce both wood briquettes and charcoal briquettes.
2. Screw mini briquetting press machine main parts adopts high hardness alloy steel, which prolongs the service life.
3. The gear box is equipped with lubrication device, which makes it be lubricated regularly.
4. The automatic cutting system of screw briquetting press machine makes sure the uniform length of briquettes.
5. Tetragon and hexagon briquettes or charcoal briquettes with hole produced by screw small briquette machine are easy to burn completely with little ash, improving the combustion efficiency.
6. It is convenient for the end products of screw  briquetting press machine to store, transport for their regular shapes.
7. The screw briquetting press machine has the advantages of stable running, continuous production and flammable property (because the charcoal briquette is hollow and the surface has carbide layer), etc.
