Description

Technical Field

[0001] The present application belongs to the technical field of material dehydration and granulation, and more specifically, to a composite dehydration and mixing granulation equipment. Background Art

[0002] The particle size of the colloid particles formed by the low-strength, high-randomness SBC polymer elastomer during the coagulation process is about 2 mm. When the colloid particles of this size enter the currently used dewatering machine, the dewatering screen will lose its dewatering function in a short period of time, thus affecting the performance of the entire dewatering granulation unit.

[0003] At present, the post-processing dehydration process of SBC production is: pre-dehydration by vibrating dehydration screen + deep dehydration by extrusion dehydration machine. This dehydration method is not suitable for the dehydration of low-strength and high-random SBC polymer elastomer particles. There are a lot of particles that are lost in the vibrating dehydration screen area, which affects the cost and increases VOC. S Secondly, due to the small particle size of the colloid particles, when the material enters the dehydration area of ​​the extrusion dehydrator, the sieve holes of the dehydrating body are easily blocked by the colloid particles, which causes the dehydration function of the dehydrating body to fail and reduces the efficiency of the unit.
