Control of moisture, etc. in semi-finished white fertilizer products
Thread Content
This post was last edited by victor187187 on 2018-1-14 08:30. White fat products with a moisture content of 20% or less are considered qualified products. 1. What is the appropriate moisture content for semi-finished products? Should factors such as the dehydration capacity of centrifuges be taken into account? 2. What is an appropriate level for water-soluble phosphorus, and what are the influencing factors? From what I understand, the moisture content in the semi-finished product should be kept between 30% and 40%, while the amount of water-soluble phosphorus should be below 2%. I invite all members to participate in the discussion. Thank you!
Bai Fei is a by-product of feed-grade calcium hydrogen phosphate; its scientific name is fertilizer-grade calcium hydrogen phosphate, and its chemical composition consists of calcium hydrogen phosphate with 2 molecules of water of crystallization. In contrast, the main components of superphosphate are calcium dihydrogen phosphate with 1 molecule of water of crystallization and anhydrous calcium sulfate – the two are not the same substance and have different uses
