How to Briquette the Bio-Mass

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 i.e. Any type of Agricultural waste or forestry waste can be also briquetted individually or in combination without using any binder.

  • Raw material like Saw Dust Is screened and stalk (Forest & Agro waste) are chopped by cutter chipper cum Grinder (Single Action) if the raw material size is larger than 25mm
  • For using material of two or more types, It should be mixed in suitable form.
  • If raw material has high moisture it should be reduced by Sun drying or using flash drier. Say if the moisture level is higher than 15% there would be a requirement of Dryer.
  • Hammer mill grinder is used to grind the material to get desired grain size.
  • Raw material (desired grain size) is transported by pneumatic system to holding bins fixed over Briquetting Press.
  • By Screw conveyor, material is discharged from bin to the press.
  • Material is compressed by ram through taper bored die. By compression temperature is raised & lignin come to the surface and binds the material by its natural binder.
  • Briquettes are formed in shape of log and it is automatically pushed through cooling line to the storage point.
