Sawdust Wheat Straw Log Fuel Briquettes Making Machine Production Line

Briquettes are made by grinding Biomass and sawdust into a homogeneous pulp and forming this into a briquette under very high pressure. High pressure & pressing releases one of the natural components of wood - lignin which has the property of becoming liquid at high pressure (temperature) and, as it subsequently cools, it binds the wood together in its new form Briquettes.

Almost any biomass can be briquetted. Briquetting plants set so far in India are using Saw Dust, Bamboo dust, Bagasse, Cotton Stalk, Coffee husk, Groundnut Shell, Mustard Husk/Stalk, Pine Needles, Rice Husk, Sugar Mill Waste, Jute waste, Coir pith and other wastes & residues like Castor Shell, Red Gram Stalk, Tobacco stem, Tea Waste, Sander Dust, Tree Bark, Wild Grasses & Shrubs and Sander dust etc. can be also be briquetted individually or in combination without using any binder.

The final bio-fuel briquette is made by the advanced biomass briquetting machine. This bio-fuel briquette is 45-80mm in diameter, occurs in the hollow quadrangular or hexagonal cylinder or hollow hexagonal with a 15-20mm hole through the body. 

As the need of pollution free environment, the product has a large scope of marketing. The briquettes can be used as a substitute of any fuel in following fields : 
Boilers : It can be used in the boilers of Paper Mills, Sugar Mills, Dyeing houses, leather, lamination industries, Vanaspati units, Food Processing Units, Oil Extraction Units, Solvent Extraction Plant and many other plants and industries.. 
Furnace & Foundries : It can be used for metal heating & melting (where melting point is less than 1000d/cel.) 
Brick Kilns : It is the total, substitute of steam coal. 
Residential & Commercial Heating : For winter heating in Cold areas and Hotels, Canteens, Cafeterias and house hold kitchen appliances etc.

 structure &working principle 

The main machine include the electrical motor, heating system,  switchboard, Temperature control device, rack, transmission lubrication system, the screw propeller, molding barrel, etc.

Sawdust 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.

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
5. Carbonized the briquette stick

1.Featured with simple structure, convenient operation, small size, covering little space, labor saving and power saving.
2.Equipped with automatic electric heating device, the material humidity can be adjusted at all times to ensure the molding effect.
3.The main parts of the machine are made of wear resistant material with specific treatment that can ensure continuous production and durability.
4.Suitable for pressing various biomass materials, low power consumption and high production efficiency.
5.The Wood sawdust briquette machine is equipped with four bearings, improving the stability and durability of the machine.
6.Lubricating adopts oil-immersed lubrication, which can be used for many years if there is enough oil.
7.Enlarged screw pitch can increase the feeding amount and improve the yield.
8.Improved forming cylinder structure can reduce the friction between the machine and raw materials, and increase the density of briquettes.
