How to improve the yield of feed-grade calcium hydrogen phosphate.
Thread Content
Our factory uses a two-step precipitation method to produce feed-grade calcium hydrogen phosphate, with white calcium fertilizer as a by-product. We would appreciate it if those with experience in this industry could share the improvement measures they have adopted, based on their own factory’s experiences.
The degree of neutralization needs to be controlled more precisely. . . . . . . . . . . .

Calcium hydrogen phosphate is simple to produce; a careful analysis is all that’s needed! The focus should be on phosphoric acid; by handling it properly, the level of phosphoric acid impurities can be reduced.
This is a good question, but it’s necessary to understand your specific process. If it’s in Deyang, aim for a yield of 83%; if that target isn’t achieved, please call 15680117336 – it’s free!
