Granulator parameters affected by particle feed PDI mainly include yield, ring mode speed, ring mode working area, die roll gap, and ring die compression ratio. NQS China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
When the other parameters of the granulator are constant, the higher the output, the more loose, the more the particles, the finer many. This is because of high yield, it is shorted in the mold hole, and the power consumption of its unit production consumes less power, and the particulate compaction is not enough, and therefore, in order to control the PDI of the particles, the granulator should use appropriate Feeding speed, controlled yield.

When the speed is high, the feed is not easy to form a suitable material layer thickness in the extrusion zone and the feed is difficult to enter. In the mold hole, the relative sliding or even blocking of the pressure roller and the ring mold is caused, affecting the quality of the particles, and the particles produced at the same time are smashed out with a larger centrifugal force, and the particles are easily touched, and there are more surface cracks. Suitable loop mode speed is 6 ~ 9 m / s (Li Haibing, 2005), which is generally difficult to granulate raw materials to select a lower speed, and it is easy to granulate raw materials to select a higher speed.

The larger the working area of u200bu200bthe ring mode, the more the number of holes, the time to stay in the mold hole The longer, the longer the time of extrusion, the more dense, the more the tissue of the particles, the higher the particles PDI.

Granulator can work normally when the mold roll gap is set between 0.1 to 0.5 mm, within which the gap is within this range The, the more power consumed in the same yield, the higher the particles PDI, because the material in the material layer in the extruded region has a pre-compression force. For ring molds of different mold pore diameters, generally pressing small diameter particles select a smaller gap, pressing a larger diameter particles to select a large gap.

The compression ratio is the ratio of the effective length and the diameter diameter of the ring die hole. For a ring model of the same aperture, the larger the compression ratio, it means that the thicker the ring mode is valid, the more frictional resistance, the frictional resistance, the frictional resistance of the feed is extruded, and therefore, in order to obtain A higher particle PDI can increase the compression ratio of the ring mold. Different particulate feed varieties are different for PDI. Generally, the requirements for the aquatic feed are higher than that of livestock, because high PDI can increase the stability of particulate feed in water, reduce water pollution and feed waste. The compression ratio of the ring model is not, the better, because high compression ratio means high energy consumption and low yield, must choose reasonable selection according to the formulation characteristics, the specific selection method will no longer be discussed.
