The heptagonal roller of the granulator is easy to disassemble and clean. The mechanical transmission system is all enclosed in the machine body and is equipped with a lubrication system. The whole machine runs smoothly. However, in actual use, it will always be blocked. Affected normal work, need to find out the reason.
Reasons for blockage of granulator:
1. The ideal production conditions of the dry granulator and other granulators in the production process are: the raw material moisture is suitable, the steam quality is good, and there is sufficient tempering time. The correct use of dry saturated steam for granulation can effectively improve the output of the granulator and the quality of the pellets. To ensure good pellet quality and high output, in addition to the normal operation of each transmission part of the pelletizer, the quality of the dry saturated steam entering the pelletizer conditioner should also be ensured.
2. The gap between the mold rolls is too large, causing the material layer between the mold rolls to be too thick and unevenly distributed, and the pressure roll is easy to slip due to uneven force. Once the squeezing force of the die roller on the material is less than the resistance of the inner wall of the die hole to the material, the material cannot be squeezed out and the machine will be blocked.
3. To make pellet feed meet the market's competitive demands, it must be of high quality. The conditioning effect of the material before granulation is very important, because it directly affects the output of the granulator and the quality of the granules, especially the water stability of special aquatic products is an important indicator.
The thickness of the pressed tablet can be adjusted appropriately according to the size of the particles, so that the roundness of the particles after sizing is better, and the structure of the sizing knife can also be improved to improve the roundness of the particles. Before choosing a dry granulator, customers can send some materials and do a test first.
