NPKs are important to crops. All plants need nitrogen, phosphorus and potassium to grow.Npk fertilizer production line is composed of crusher, fertilizer mixer, granulator (drum granulator), screening machine, fertilizer coating machine and fertilizer automatic packaging machine.

Manure biomass organic fertilizer equipment supporting facilities need alcohol turner, organic fertilizer pulverizer, drum screening machine, horizontal mixer, organic fertilizer equipment disc granulator, double roller granulator, organic fertilizer fermentation equipment discussion Soil layer deterioration cause professional knowledge rotary drying equipment, cooling machine, screening machine, outer film machine, automatic packaging machine, belt conveyor and other machinery and equipment.

The npk manufacturing process is similar to the organic fertilizer production line. The fertilizer production line has three configurations: high, medium and low. Large-scale fertilizer plants should adopt a complete set of production configurations, so that the appearance and nutrient content of the finished products can meet the market requirements. Promotion has a greater advantage. The NPK production line with low and medium configuration is suitable for small and medium-sized fertilizer plants. The sales range of finished organic fertilizers is limited to nearby areas, and some processes in the organic fertilizer production process need to be completed manually.

The location of the factory is equally important before choosing to buy equipment, which affects the long-term development of the enterprise. The overall planning principle for site selection: raw materials are nearby, the site has convenient transportation and good infrastructure, and the original buildings should be used as much as possible to reduce the investment scale, improve the efficiency of capital use, and give full play to the demonstration function of the project. Away from residential areas, choose downwind vents; adjust measures to local conditions, make compact arrangements, and try to use abandoned land as much as possible: the living area is separated from the factory site to maintain environmental sanitation.
