INCREASING CRYSTAL GRAIN SIZE OF AMMONIUM SULFATE AND ITS DEVICE |
摘要 |
The average size of ammonium sulfate crystals is increased by passing undersized ammonium sulfate crystals through a multistage apparatus in which the crystals are contacted with an aqueous ammonium sulfate spray in a first heated chamber to increase the average size of the crystals, the enlarged crystals thereafter passing through a second heated chamber to dry the enlarged crystals. <IMAGE> |
