Method for preparing high-concentration round grainy potassium muriate

Abstract

The invention relates to a production method for potassium chloride with high concentration and rounded grain shape, which comprises the steps that: powdered potassium chloride with certain fineness in which the content of potassium oxide is 60 percent or more is added into a round granulating disc or a revolving drum granulator, potassium chloride saturated solution is sprayed according to certain proportion as granulation liquid phase for carrying out rounding beading granulation, and then drying and sieving are carried out to generate the rounded-grain-shaped potassium chloride. The content of kalium reaches 60 percent or more. The production method is characterized by simple operation technology, great production capability, wide scope of grain diameter of products, round grains, high intensity, and the like, and generates no waste during production, which has the advantages of energy saving and environmental protection, thereby having very wide market prospect.

Description

A kind of manufacture method of high-concentration round granular potassium chloride technical field The invention relates to a method for producing potassium chloride, and particularly discloses a method for producing high-concentration round granular potassium chloride with a potassium oxide content of 60% or more. Background technique Potassium chloride is a very important type of potash fertilizer. At present, the main forms in the market are powder and irregular particle shapes. The demand for potassium chloride products is becoming more and more urgent, especially the coated controlled-release potassium fertilizer, which has higher requirements for core materials, requiring uniform and round particles, high concentration and certain strength. Because potassium chloride itself has no viscosity and plasticity, it is an inorganic mineral, and it is not easy to granulate by conventional methods, and it is very difficult to produce high-concentration round granular potass...
