The compound fertilizer production line produced by the disc granulator machine for fertilizer has a low spheroidization rate, so it is necessary to implement a technical transformation plan for the disc granulator equipment.

Technical Transformation of Disc Granulation Compound Fertilizer Production Line

1. Reasons for the low ball formation rate of the compound fertilizer production line

(1) The angle of the disc granulation plate and the arrangement of the scraper plate are unreasonable;

(2) The dry humidity of the raw materials is unstable, and the moisture content is difficult to grasp;

(3) The amount of binder is unstable or the quality is not good enough

Transformation measures of the disc fertilizer granulator machine:

(1) Adjust the angle of the pelletizing plate

(2) The dry humidity of the raw materials should be kept stable, moisture-proof and rain-proof

(3) Choose an adhesive with strong adhesion, and the dosage should be determined according to the size of the raw material and the amount of powder surface

2. Serious reasons for the drying machine sticking to the wall

(1) The temperature at the inlet of the dryer is too high, which causes the heat-sensitive substance (such as urea) in the dried substance to melt and increase the viscosity

(2) The structure and arrangement of the lifting plate inside the drying cylinder are inappropriate

(3) Due to the unreasonable internal layout of the drying cylinder, the resistance is large and the material

The material flow is slow, and the heat exchange cannot be carried out normally. Material absorption in the drying section

There is more heat, so that some materials (such as urea, ammonium sulfate, etc.) are in a molten state, and the viscosity increases and adheres to the lifting plate or the body wall

Transformation measures:

(1) The water content of the disc granulation section should be appropriate to improve the technical level of the granulator, and at the same time make appropriate adjustments to the formulation process

(2) The water in the granulation section should be appropriate, improve the technical level of the granulator, and make appropriate adjustments to the formulation process

(3) Control the inlet temperature and install an automatic temperature controller
