Pressure adjustment of roller granulator during fertilizer granulation
Extrusion force of double roller press granulator is an important parameter for safe and stable operation of granulator. The pressure of double roller granulator directly affects the extrusion effect and quality of fertilizer granulation process. Therefore, the pressure regulation of roller press granulator is an important control parameter in the granulation process. Proper pressure can increase the output of fertilizer granulation, reduce energy consumption and prolong the service life of granulator. The granulation mode of roller granulator is different from that of drum granulator . If the pressure of roller granulator is too small, there will be more gaps between fertilizer particles, which can not meet the pressure required for material extrusion, and dense filter cake will not be formed, which will affect the effect. If the pressure is too high, it is easy to cause "re polymerization" phenomenon between the material particles, which makes the filter cake difficult t...
