Lignin extraction process

LignoBoost is a patented extraction process divided into two steps: a separation step, followed by a washing step. Dividing the extraction into two steps makes it possible to optimize the conditions in each step and produce a very high quality lignin. It also provides several options for adjusting the characteristics of the lignin.

Grinding Wheel: Specifiions Manufacturing Process by .

 · In grinding process, the process of breaking of abrasive grains exposing sharp edges is called as friability. When the grains break down under pressure, the new edges for cutting emerge or are exposed. During this process, the binding material also gets removed and the grains which have become blunt get free and are removed.
