Grinding energy

Various hypotheses relate the net grinding energy applied to a process and the size reduction achieved. The first, proposed by Karl von Rittinger in 1867, states in Eq. (27) that the energy necessary for size reduction is directly proportional to the increase in surface area. [Pg.3894]

The result was the discovery that a high density powder, dubbed ECO-FUEL II, could be produced by treating the partially comminuted MSW with small amounts (around 0.5%) of readily available commodity chemicals which at temperatures under 150°C would embrittle the cellulosic materials in MSW and, with low levels of grinding energy, produce a powdered fuel of high density. The process is protected by patents. [Pg.146]

The grinding energy required for ductile mode is different from that for brittle mode. Based on the concept of the critical depth-of-cut d, which has attracted considerable attention so far, a general description has been successfully introduced to express the brittle-ductile relationship. [Pg.16]

The total grinding energy E, required for brittle materials is the sum of the energy for brittle grinding Ef and the energy for ductile grinding Ep. Out of Eb, Ef is expressed as... [Pg.16]

Dividing this by the removed volume V at the brittle mode or Vp at the ductile mode, the specific grinding energy pf and Xp are given as... [Pg.16]

HPSN. This same argument would also apply to all the other workpiece materials as listed in Table 3.1 with the possible exception of RBSN. Therefore, most of the grinding energy must be expended by ductile flow, even though material removal is mainly by brittle fracture. [Pg.78]
