Abstract

The invention relates to a tower granulation sustained and controlled release compound fertilizer production system. The system includes: a first conveying line and a second conveying line, wherein each conveying line respectively comprises a mixing device, a sieving machine, a screw conveyor, a tower hoister and a mixing silo that are connected in order; a first stage mixing tank connected to the mixing silo of the first conveying line; and a second stage mixing tank, which is connected to the mixing silo of the second conveying line, and is connected to a finished product bin through a uniform mixer I, a granulator, a granulation tower, a cooling unit, a sieving apparatus and an oil film coating apparatus in order, and the oil film coating apparatus is connected to a coating agent melting device. Specifically, the coating agent melting device consists of: a melting tank and a stirrer disposed in the melting tank, the upper end of the melting tank is equipped with a coating oil inlet, the lower end of the melting tank is equipped with a coating oil outlet, and a heating device is arranged in the melting tank.

Description

Technical field [0001] The invention relates to a fertilizer production system, in particular to a high-tower granulation slow and controlled release compound fertilizer production system. Background technique [0002] Slow and controlled release compound fertilizer has the advantages of slow release of nutrients, prolonged fertilizer efficiency and utilization rate, and has become one of the key technologies in the compound fertilizer industry. The slow and controlled release compound fertilizer coating device is an indispensable important device. [0003] After the traditional compound fertilizer is applied, the fertilizer nutrient release rate is fast, and the soil and rainwater are lost seriously, and the nutrient elements are wasted seriously, which cannot meet the characteristics of crop growth. Therefore, there is a need for a slow nutrient release rate and a longer release period. Long, fertilizer that can meet crop growth needs during the entire growth period of crops. S...
