Lynne Wong's PhD thesis

The extent of the drop in CCS agrees well with that estimated by Brotherton (1980) who
showed that the rate of change of CCS per unit of extraneous matter was -0.16, as
compared to -0.16, -0.14 and -0.14 for 1 unit of dry trash, green leaves and cane top
respectively shown in Fig 2.20.
The influence of extraneous matter on boiling house recovery and overall recovery are
shown in Figs 2.21 and 2.22. The effects of dry trash appear to be most detrimental on
these two aspects of milling quality.
