Briquetting technology
Briquetting is the transformation of a powdery or granular product into a larger more convenient size. This is accomplished by compacting the product with a roller press sometimes in the presence of a binder material. The briquettes can be produced with high or low pressure and can undergo mechanical or thermal treatment according to the characteristics of the processed material, the binder used and the desired end product.
Anyway, briquetting is the only one way to change the powdery material into briquettes which is suitable for transporting, in the meantime, this way also saves engery.
