Liquid fertilizer production line

(1) The solid raw materials (such as urea, potassium dihydrogen phosphate) were added too quickly without sufficient contact with the solvent (water); (2) The solvent temperature was too low (below 15℃), which reduced the solubility of the raw materials; (3) The particle size of the raw materials was too large, resulting in a slow dissolution rate.

(1) Weighing error during manual feeding (more than ±2%); (2) Sensor failure in the automatic feeding system, resulting in inaccurate measurement; (3) Density fluctuations of liquid raw materials (such as humic acid solution, amino acid mother liquor) cause deviations when measured by volume.
