We all know that using the fertilizer manufacturing technology to make the organic fertilizer or inorganic fertilizer.But the fertilizer type is complex and how we to make the humic acid compound fertilizer using the fertilizer manufacturing technology.What type fertilizer macines to be equipped in the fertilizer manufacturing process for producing the humic acid compound fertilizer ?
The humic acid compound fertilizer is a kind of compound fertilizer made by  crushing humic acid,inorganic fertilizer and microelement fertilizer respectively according to the supply of soil nutrients and crop,and mixing and granulating according to a certain proportion.
Properties:gray black shaped particles,partially dissolved in water solution close to neutral,non-toxic.It can improve the utilization rate of chemical fertilizer,stimulate the growth of plants and improve the properties of soil.
Some pictures of the fertilizer production lines supply for you:

Production method:take peat,lignite and weathered coal as raw materials,first use sulfuric acid to carry out acidification reaction with humic acid in weathered coal to produce free humic acid and calcium sulfate with small solubility,then use ammonium bicarbonate to neutralize humic acid to produce water-soluble humic acid ammonia,add proper amount of nitrogen,phosphorus,potassium and medium and micro elements according to the ratio requirements,and then using the fertilizer crusher machine o crush,measure,mix using the fertilizer mixer machine and granulate using the suitable type fertilizer granulator machine,after that,using the fertilizer screener machine to separate the quality fertilizer granulator from the inquality fertilizer granulator,throug drying,cooling and packing to produce the humic acid compound fertilizer.
