【Abstract】 Filtration and washing are important operational units in the production of potassium nitrate. In order to achieve continuous filtration and washing of potassium nitrate, a spiral filtration washing machine was experimentally applied in the production of potassium nitrate. Production application tests have proved that the use of a spiral filter-washing machine for the production of potassium nitrate is simple to operate, has a good washing effect, a large production capacity, low energy consumption, and realizes continuous filtration and washing of potassium nitrate, with stable operation.更多还原
