Disc granulator is one of the compound fertilizer production equipment. Its shape is mainly composed of disc, simple structure and intuitive granulation. In the production, by changing the parameters of the pelletizing plate, the production capacity of the equipment is improved, and the efficiency of the NPK fertilizer production line is improved.
Generally speaking, the diameter of Pan fertilizer granulator mainly depends on the output. Different fertilizer machine manufacturers will combine other equipment of NPK fertilizer production line according to their own conditions, such as annual production capacity. The annual production capacity of a 2-meter diameter disc granulator can reach more than 10000 tons, and the annual production capacity of a 2.2-meter diameter granulator can reach more than 15000 tons.
Therefore, the annual production capacity should be considered from the design point of view when selecting the disc diameter.
Pan fertilizer granulator
Once the diameter of the pan fertilizer granulator is determined, the plate height can also be basically determined. Generally speaking, the larger the diameter, the higher the disc height. However, the height of the disc also affects the granulation time. Due to the difference in friction coefficient between the raw material and the disc surface, the particles generated on the disc will have a grading effect.
Small particles will stop near the bottom of the disc, and large particles will be discharged from the edge. Therefore, the higher the edge of the disc, the longer the granulation time. If the disk is too high or too low, the ball forming time is short and the particle size is relatively small. Therefore, on the one hand, the plate height will affect the size of product particles discharged from the granulation plate, on the other hand, it will also affect the output.
Because if the material in the tray stagnation time is too long, the slower the product discharge speed, the larger the product particles, the larger the particles that do not meet the standard, and the lower the proportion of ball formation rate, it is very important to select the tray height reasonably.
