| description | The invention relates to a rounded grain potash fertilizer production method, which is characterized in that potassium chloride or potassium sulfate solid powder is taken as a base raw material of a potassium nutrient, liquid state urea is taken as a binder, a high pressure nozzle in a rotating cylinder comminutor is used for sprinkling the liquid state urea to potassium chloride or the potassium sulfate solid powder and a cycle return material to form the surface of a mixing material, granular bonding powder can be gradually increased during rolling of the material, potassium chloride or potassium sulfate-containing spherical particles which take urea as the binder are formed, finally the mixing material with different particle sizes is cooled and screened to obtain the spherical grain potash fertilizer finished product. The rounded grain potash fertilizer can effectively preventing layering of the fertilizer during transport or application process and can ensure the uniformity of the fertilizer nutrient, so that the rounded grain potash fertilizer can be the special-purpose raw material of a formula fertilizer. |
