The structure of the outer surface of the pressure roller mainly has a cogging type, a sealed groove type and a honeycomb type. The cogging type pressure roller has good performance and is widely used in livestock and poultry feed mills. However, due to the sliding of the feed in the tooth gap, the wear of the pressure roller and the ring die is not uniform, and it is worn at both ends of the pressure roller and the ring die. It is more serious, and it is difficult to discharge the two ends of the ring mold for a long time, and the produced particles are shorter than the middle part of the ring mold. The cogging type pressure roller with sealing edge is mainly suitable for the production of aquatic products. The water product is easier to slide when squeezed. Because the sides of the tooth groove are sealed, the feed is not easy to slide to the sides when the feed is squeezed. It is relatively uniform, and the wear of the pressure roller and the ring die is relatively uniform, so that the length of the produced particles is also uniform. The advantage of the honeycomb type pressure roller is that the ring die wears evenly, and the length of the produced particles is also uniform, but the performance of the coil material is poor, thereby affecting the output of the granulator, which is not as popular as the cogging type in actual production. At present, there is a new type of pressure roller surface structure in foreign countries.
