Abstract

Drying the Borate Concentrate in Drum is one of the most useful method to reduce the total waste volume. Microwave is one heat option, To determinate the feasibility for Microwave-Drying of Simulated Borate Concentrate in Drum, a Sequence of tests have been designed, including pre-test in microwave oven and batch-test in 12L microwave device. Liquid temperature, evaporation rate and moisture have been recorded along with the drying process. The result said that it is feasible for microwave drying simulated borate concentrate in drum. For borate concentrate will generate “water diffusion barrier layer” during the drying process, batch-feeding is the prefer option; the most suitable batch-feeding amount is a compromise for evaporation, gravity, and intermolecular forces which affect the migration of water molecules. It is recommend that the batch feeding should be used for MDSBCD and the off gas temperature can be a sign of subsequence feeding; the first feeding must be moderate to avoid microwave reflection; the little batch-feeding amount is, the better product characters are. In the test, it is reasonable that the material can be supplemented or the drying be stopped when the temperature of ending vent raises to 72°C and keep increase rapidly; the first-feeding can be 2kg SBC, after- feeding can be 1kg SBC.
