AI Technical Summary
Existing polypropylene composition drying equipment suffers from problems such as unidirectional stirring, leading to material accumulation, uneven drying, and some materials being over-dried or under-dried, which affect the quality of finished products and production efficiency.
The combination structure of gear disk and linkage gear drives the rotating shaft to perform inclined circumferential and rotational motions. Combined with the compound motion of spiral blades and stirring rods, and guided by conical guide blocks, it realizes multi-dimensional tumbling and circulation to ensure uniform drying of materials.
It improves the uniformity and efficiency of drying, avoids material accumulation and local overheating, ensures stable quality of subsequent processing, and reduces production time and costs.
