Influence of the size of disc granulator on production
2019/11/11
The disc granulator is one of the compound fertilizer production equipment. Its shape is mainly composed of a disc, the structure is simple, and the granulation is intuitive. In the production, by changing the parameters of the granulation tray, the production capacity of the equipment is improved, and the efficiency of the NPK fertilizer production line is improved.
Generally speaking, the diameter of the disk fertilizer granulator is mainly determined by the output. Different fertilizer machine manufacturers will make matching combination with other equipment of NPK fertilizer production line according to their own conditions, such as the annual production capacity. The annual production capacity of the disc granulator with a diameter of 2 meters can reach more than 10000 tons, and the annual production capacity of the pelletizer with a diameter of 2.2 meters can reach more than 15000 tons. Therefore, the selection of the disc diameter should be considered from the perspective of the design annual production capacity.
Once the diameter of the disc fertilizer granulator is determined, the disk height of the disk can also be basically determined. Generally speaking, the larger the diameter is, the higher the disc height is. However, the height of the disc height can also affect the pelletizing time of the fertilizer on the disc. The particles generated on the disc will have grading effect due to the difference of friction coefficient between the raw material and the disc surface. The small particles will stagnate near the bottom of the disc, and the large particles will be discharged out of the edge, so the higher the disc edge, the longer the pelletizing time. If the disk is too high and too low, the ball forming time is short, and the particle size is relatively small. Therefore, on the one hand, the plate height can affect the size of the product particles discharged from the granulation plate, on the other hand, it can also affect the output. Because if the material stagnates too long in the tray, the slower the product is discharged, the larger the particles of the product, the more the particles that do not meet the standard, and the lower the proportion of the ball forming rate, it is very important to choose the tray height reasonably.
