Abstract

The invention is suitable for the technical field of fertilizers and provides a potassium chloride particle fertilizer and a preparing method thereof. The fertilizer comprises an adhesive material, a quick-setting additive, a wetting agent, an auxiliary granulation material and potassium chloride. The preparing method includes preparing a potassium chloride granulation formation auxiliary agent, and preparing potassium chloride particles. The potassium chloride particle fertilizer and the preparing method which are provided in embodiments have characteristics of simple operation, short production period, low energy consumption, low cost, a granulation rate not less than 75%, and convenient industrial production. The strength of the prepared potassium chloride particles is not less than 20 N. The prepared potassium chloride particles are short in dissolution time.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a potassium chloride granular fertilizer and a preparation method thereof. Background technique [0002] Potassium chloride is a high-concentration quick-acting potassium fertilizer, and it is also the most widely used potassium fertilizer variety. Potassium chloride has good physical properties, low hygroscopicity, soluble in water, chemically neutral reaction, and belongs to physiological acidic fertilizer. [0003] The current potassium chloride products are mainly powdery products, but powdery potassium chloride has the disadvantages of easy dust, poor fluidity, and easy hardening after long-term storage. And because the viscosity of powdery potassium chloride itself, plasticity are poor, conventional production process is difficult to granulate. The existing methods of producing potassium chloride granular fertilizer are mostly: using powdery potassium chloride as raw ...
