Scientists of Perm Polytechnic University have increased the fluidity of fertilizers by changing the composition of the anti-caking component. They published the results of their work in the collection of “Chemistry” conferences. Ecology. Urbanism.»
Potassium chloride is one of the main potash fertilizers. It is often used in large farms. Fertilizer is quite expensive, often exported to other countries. At the same time, potassium chloride is prone to clumping, which worsens its consumer properties.
Usually the fertilizer is treated with an amine, an anti-caking agent. But amines also increase the so-called dustiness of the product, and therefore the transport of fertilizer becomes more laborious and laborious.
Russian scientists treated the chloride with the usual brands of amines for the manufacturer and a solution of amine hydrochloride.
The halurgic potassium chloride was treated with an anti-caking agent and then stored under a load of 30 times its own weight for 24 hours.
“After storage, the granulometric composition of potassium chloride was measured by the sieve method,” said Konstantin Kuzminykh, senior lecturer in the Department of Chemical Technologies.
The scientists concluded that compared to normal amine, the use of an amine hydrochloride solution can reduce the effect of destroying large sodium chloride crystals, allowing the fertilizer to flow more freely.
