Versuchsvorschrift

160.6 kg melamine, 165 kg cyanuric acid and water of 80° C. are contacted and mixed in a paddle mixer (2 m3). After mixing 2 h and reaction at 80° C. 50 wt. % melamine cyanurate slurry is formed. Water is removed by evaporation in 6 h at 250 mbar. The resulting product consists of melamine cyanurate aggregates with a dry matter content of 99.8%. The average particle size of the aggregates is 980μ with a bulk density of 725 kg/m3. The flow properties, measured in accordance with the Klein method, indicate: Flow value No. 2.
