biomass grinding characterising

Von Rittinger theory adapted to wood chip and pellet

Moreover, the levels were low, in the order of 2 Wh/kg, compared with the values when grinding biomass that had not been pre-densified (cf. Section 3.1) and also compared with grinding pellets using screens of smaller mesh diameter (2 mm, 3 mm and 4 mm).It is therefore assumed that grinding on these screens breaks down the pellet structure butget price

Grinding chips and pellets can pose problems, however. There is a lack of data for dimensioning the mill when designing power plant supply circuits. Conversely, in existing circuits, acceptance of new materials requires true scale pilot projects. More generally, little research appears to have been done overall into Þne milling of biomass.get price
