Description

Secondary agitator for dry granulator

technical field

The utility model relates to a stirrer, in particular to a secondary stirrer for a dry granulator, which belongs to the field of fertilizer processing equipment.

Background technique

In the dry granulation machine currently used, the dry powder material in the silo is agitated by the agitator to remove air while stably feeding the horizontal feeder. After the material enters the horizontal feeder, driven by the rotating screw, the material is gradually degassed in the process of moving forward, and the material with increased density is forced into the tablet press. The tablet press machine rolls the high-density material conveyed by the horizontal feeder into thin sheets through a pair of pressure rollers driven by hydraulic cylinders, and completes the degassing work again. The rolled flakes pass through the teeth of the shearing crusher, cut into pieces that are easy to granulate, and then fall into the granulator. The fragments are forced out of the sieve plate under the extrusion of the whole grain knife. After the extruded particles are sieved, the products with the particle size required by customers can be obtained. So far, the whole process of granulation has been completed. However, most of them are not equipped with a secondary agitator, which makes the particles uneven. Affect the quality and effectiveness of granular fertilizer.
