Abstract

Time consolidation flow properties of a commercial detergent powder were measured at elevated temperature of 27 °C, 37 °C and 47 °C with the Brookfield Powder Flow Tester (PFT). A substantial increase of powder cohesion was observed at elevated temperature and after time consolidation. The Jenike method for silo design was used to correlate the powder time consolidation flow properties at elevated temperature to critical outlet slot to attain arch‐free silo. The dependence of the critical diameter on temperature and time consolidation is successfully described by the model.
