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 and other raw materials, with high product granulation rate. It can produce compound fertilizers of various concentrations and types (including). Especially the granulation of rare earth and ammonium bicarbonate series compound fertilizers.
1. The npk fertilizer production line Applicability of raw materials and its wide range: it is applicable to the direct granulation of fermented livestock and poultry excrement, filter sludge from sugar factories, municipal sludge, paper sludge, distiller’s grains, straw, peat and other organic wastes, and can produce pure organic fertilizer, organic-inorganic fertilizer and bio-organic fertilizer with spherical particles.
2. High balling rate and biological bacteria survival rate: the new technology can make the balling rate high, and the new technology of drying at low temperature and large air volume can make the microbial bacteria survival rate high.
3. The process flow is short and the operation cost is low. The organic raw materials used in this process do not need to be dried, crushed and other preliminary treatment. The process flow is short and the operation cost is low.
