| Abstract: | A novel granulation technology for producing spherical wax particles that makes use of the insolubility of wax and water is developed. The granulation is stably performed in a granulator with a water‐cooling tower. The granulation process is analyzed and the influences of key factors on the process are studied. Experiments are carried out with 58# semi‐refined wax and 70# crystallitic wax in an experimental granulator which has 118 nozzles (Di = 0.96 mm, Do = 1.28 mm). The process capacity and the corresponding particle diameter are 55–60 kg/h and 4–5 mm, respectively. Using the modified correlation of Scheele and Meister, suitable operation flow rates and the corresponding particle diameters for different nozzles can be predicted. This technology has the following advantages: good particle shape with excellent fluidity, high process capacity and heat‐transfer efficiency, and a small space for the granulator. It is also suitable for producing spherical particles of other materials, which have similar physical properties to wax. |
