Series Condensing Granulating Tower

There are three phases in condensing granulating: first, pre-cooling, the temperature of raw material will change from granulating point to solidification point; second, solidification, raw material will change from liquid to solid, the temperature of material is not change in this step; third, solid material cooling, raw material will go on cooling and solidify.

Time of meltwater pre-cooling: d(s):(tl-tk)/(tc-tk)=exp(hd d/dcdpd)

Time of constant temperature solidification: c(s):c=dpcLf/hc(tc-tk)

Time of solid material cooling: s(s):(tc-tk)/(ts-tk)=exp(hs s/dCsps
