In-line dispersion equipment (such as in-line dispersers, high-shear dispersers, etc.) is widely used in industrial production for processes including mixing, emulsification and homogenization. Common faults are generally related to equipment operation, process performance and maintenance.
Typical Issue: Poor Dispersion Performance
Phenomenon: Uneven particle dispersion, excessive particle size or agglomeration.
Possible Causes:
1. Insufficient dispersion time or low rotational speed;
2. Excessively high material viscosity and poor fluidity;
3. Worn dispersion heads (rotor/stator) or inappropriate model selection;
4. Excessive feed rate exceeding the processing capacity of the equipment.
Solutions:
1. Adjust process parameters (extend dispersion time and increase rotational speed);
2. Reduce material viscosity (e.g., add solvent or raise temperature);
3. Inspect and replace worn dispersion heads to ensure the model matches process requirements;
4. Control the feed rate and adopt batch processing.
