Process flow and granulation range of npk fertilizer production line
The npk fertilizer production line will generally crush the fermentation materials that have completed the secondary aging and stacking process and enter the mixing and mixing system. Before mixing and mixing, according to the formula, N, P, K and other trace elements will be added into the mixing and mixing system to start mixing.
The mixed materials are transported to the granulation system, and the granulation enters the cooling system after passing through the dryer. The materials are screened after reaching the normal temperature. The particles that meet the requirements enter the coating machine to wrap the film and start packaging. The particles that do not meet the requirements are crushed by the pulverizer and then returned to the granulation system to continue granulation.
The npk fertilizer production line has quick effect and good economic benefits, and the complete set of equipment has compact flow layout. It reduces the energy consumption of the equipment, makes the operation of the equipment stable, has no discharge of three wastes, and is convenient for maintenance. Wide adaptability of raw materials, suitable for granulation of compound fertilizer, feed
