Apparatus and method for obtaining crystals of a defined grain size from super-saturated solutions, in particular salt solutions

摘要

The application describes a method and an apparatus for obtaining crystals of a defined grain size, with a given flow profile being maintained in the crystallisation chamber. An upward flow is maintained in the crystallising vessel by passing solution through pipe 6. The flow maintains the crystals in suspension until they reach a size and weight where they sink under gravity. IMAGE
