2011 Hot Selling Biomass Briquette Machine

Introduction:

Biomass Briquette Machine make the biomass material into briquettes. After the well preparement of raw metarial, briquetting is easy at right operation of biomass briquette press. When machine rise to over 300 centigrade, the material can be feeding continuously into briquetting press. First, the color of briquettes may be a little dark even black, but after a while, the color will be light to normal level coming out of biomass briquette machine.   

The raw material of charcoal could be :

Any types of Agro-forestry waste and forest waste can be used for make briquettes Such as maize stalks, soybean stalks, broomcorn stalks, cotton stalks, rape stalks, peanut plants, sunflower stalks, bamboo sawdust, bagasse , wood chips, rice husk, coffee husk, coir pith, jute sticks, groundnut shells, Bamboo, wood, straw dust, Mustard stalk and cotton stalks ,nutshell, coconut shell ,etc 

Appropriate Biomass Residues for Briquetting:

1. Effect of particle size and shape of the agro residues for densification. The ideal size was identified to be 3-5mm.
2. Effect of moisture. Ideal level was 8 to 12 per cent.
3. Effect of feed preheating studied and the temperature upto 90 to 110 degree centigrade for the feed was optimised.
4. Effect of mixing rice husk with bagasse and bagasse pith to achieve the briquetting of these materials

Working Principle of Biomass Briquette Machine:

Biomass Briquette machine uses a large screw to grind, compress and extrude the biomass into briquettes. The natural lignin content in biomass is liberated with wood fiber under high pressure and temperature.In the briquetting process lignin serves as the glue and combines the particles of wood together,thus binding, compressing the biomass to form into various moulds of high density briquette, such as hexagonal,quadrangular, square,etc. As your requirement, we can also change the shape to order. And the diameter of briquettes are from 50-80 mm. Moreover non-binder needs to be used during this process.

The process for producing charcoal briquette as follow:

 
1. Crush the raw material into small pieces (diameter is about 3-5mm)
2. Dry the material by machine or dried it in the sun , till the moisture is less than 12%
3. Put the material into feed let of briquette machine
4. Produce the briquette stick from biomass material without any additive
4. Carbonized the briquette stick

Characteristic of Biomass Briquette Machine:

1. No binder or noxious chemical need to use.

2. The humidity of the raw materials is controlled in 8-12%.

3. Using the advanced Hot air drying system with the perfect performance.

4. After the processing of High temperature, purification, smoke removing, the carbonizing equipment transforms the semi-finished bio-fuel briquette into a smoke-free, tasteless, non-toxic cleaning carbon.

 Advantages of biomass briquettes:

♦ Increase the net calorific value per unit volume after biomass briquetting
♦ Easy to transport and store as densified product
♦ Better solution to the problem of residue disposal
♦Uniform in size and quality as a kind of biofuel briquette
♦ Reduce excess deforestation by providing a substitute for fuel wood
