Humic Acid Compound Fertilizer Production Process

We all know that the use of fertilizer manufacturing technology to manufacture organic or inorganic fertilizers, but the types of fertilizers are complex. How do we use fertilizer manufacturing technology to manufacture humic acid compound fertilizer and what kind of fertilizer machinery needs to be equipped in the process of producing humic acid compound fertilizer?

Humic acid compound fertilizer is a kind of compound fertilizer made by crushing humic acid, inorganic fertilizer and trace element fertilizer separately and mixing and granulating them in a certain proportion according to the supply of soil nutrients and crops.

Properties: Gray-black granules, partially dissolved in aqueous solution close to neutral, non-toxic, can improve the utilization rate of fertilizer, stimulate plant growth and improve soil properties.

Production method:With peat, lignite and weathered coal as raw materials, first acidification reaction with sulfuric acid and humic acid in weathered coal to produce free humic acid and calcium sulfate with small solubility, then neutralize humic acid with ammonium bicarbonate to produce water-soluble humic acid ammonia, adding appropriate amount of nitrogen, phosphorus, potassium and medium and trace elements according to the ratio requirement. Then it is crushed and measured by fertilizer grinder, mixed by fertilizer mixer, granulated by suitable fertilizer granulator, after that, the high quality fertilizer granulator is separated from the low quality fertilizer granulator by fertilizer sieving machine, dried, cooled and packed to produce humic acid compound fertilizer.
