Summary

       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

      Main factors which affect granules quality:

1. Temperature of raw material: temperature of raw material could affect capacity of equipment directly.
2. Properties of raw material: different properties raw material has different granulating ability, it will affect granulating process, quality and specification. Main property: melting point (softening point), specific gravity, heat transfer coefficient, crystalline properties, viscosity and liquid surface tension.
3. Viscosity (or surface tension), temperature could affect granules quality.
