DESIGN AND PRACTICE OF EVAPORATION CRYSTALLIZER IN VACUUM PAN SALT MAKING

摘要

In the application by many factories, the backward forced circulation and axial discharge evaporation crystallizer with external heater has been proved to be successful and vigorous. This new equipment should be further researched, improved, popularized and perfected. This article elaborates the characteristics of this equipment on the bases of hydromechanics, crystallization mechanism, specific design parameters and the selection of materials.
