Embodiment

[0014] Take the production of 100kg of humic acid compound fertilizer containing 30% of nitrogen, phosphorus and potassium as an example, the formula is as follows:

[0015]

[0016] The process flow is as follows:

[0017] The activated weathered coal is pulverized to 80 mesh in a pulverizer. Activate the pulverized weathered coal in the mixer → add water to the activated weathered coal to a water content of 70-80% → put potassium sulfate, potassium chloride, urea, and ammonium phosphate into the mixer and stir well → put it into the reaction kettle, at 50 ° C Insulate at -60°C for 2-3 hours, so that the water content of the reactants in the kettle is 30-35% → enter the granulator for granulation → enter the dryer for drying and cooling (drying, the inlet temperature of the cooler is 150°C , the outlet temperature is the normal temperature of the workshop) → screening → packaging.
