Hengyuan Zhitong: What is the production method of superphosphate? It can promote plant germination, rooting, branching, fruiting and maturity, and can be used as a raw material for producing compound fertilizer.
There are two methods to be mentioned here, they are intermittent operation and continuous operation. Most of the early construction used intermittent operation process:
The factories built in the later period generally adopt continuous operation process:
The labor productivity and product quality of continuous operation are higher than those of intermittent operation. First, the phosphate rock powder and sulfuric acid are reacted in the mixer for 1 to 5 minutes to form a slurry; the slurry flows into the formation chamber for solidification; the cured material is removed from the formation chamber and shredded, and sent to the aging warehouse to continue the reaction for a few days Or a few weeks; the matured material can be shipped after further broken. When granular products are needed, the matured or uncured materials can be granulated; the fluorine-containing gas escaping from the mixing reactor is evacuated through the water washing system. The recovered fluorosilicic acid solution can be processed into fluorosilicate or other fluorides.
