Demonstration article: batch or continuous blending for filled compounds
CPEA Approved Article (China Plastics Equipment Alliance)
Demonstration record: which blending arrangement fits a filled-compound line depends on how many recipes the line runs and how the composition is held — this placeholder article shows the reading layout.

The short answer
A batch blender fits a line that mixes several recipes per shift and feeds an extruder from a buffer; a continuous blender fits a line that runs one recipe for days and needs the composition held at the throat. The decision is made by recipe count and shift pattern, not by throughput alone.
How the two arrangements differ
| Question | Batch blending | Continuous blending |
|---|---|---|
| Recipes per line | Many, changing per shift | One, stable for days |
| Where composition is set | In the blender vessel | At the weigh feeders |
| Typical companion equipment | Ribbon or paddle mixer plus buffer bin | Loss-in-weight feeders above the extruder |
| Watch-out | Batch-to-batch drift if the cycle is rushed | Composition drift if a feeder loses its weight signal |
Questions that settle the choice
- How many recipes does the line run per week, and how long does a changeover take?
- Is the filler free-flowing, or does it bridge in the hopper?
- Does the downstream process tolerate the composition window of a batch?
