Process notes

Deagglomeration and fines control

Open agglomerates from granulation, carbonization, graphitization or other processes while limiting further damage to useful particles.

How it works and what it targets

Deagglomeration separates weakly bound particles; milling may instead fracture the particles themselves. These objectives require different energy and product evaluation. Adjusting intensity, residence time and classified discharge can release agglomerates while limiting unnecessary fines. Fragile primary particles require more careful selection of the action applied.

Reference process steps

  1. 1Identify agglomerate structure and primary-particle size to define what should be separated.
  2. 2Begin trials at lower intensity and adjust feed and residence progressively.
  3. 3Remove acceptable particles through classification and measure residual agglomerates and fines.

Configuration and operating conditions

Route selection

Mechanical deagglomeration, controlled jet pulverization and standalone classification are separate candidates, depending on agglomerate strength, coatings and particle fragility. Granulated foods, polyacrylamide, urea and battery materials need different acceptance criteria.

Closed circuits and product protection

Moisture- or oxidation-sensitive feeds may require nitrogen circulation and sealed conveying. For coated graphite, evaluate coating integrity as well as D50.

Information needed for selection

Provide before/after samples or microscopy, the process causing agglomeration, primary/agglomerate sizes, fines limits, coating requirements and target output.

Discuss selection inputs

Trial and acceptance considerations

Compare full size distributions, residual agglomerates, morphology, fines mass and function. Distinguish released agglomerates from fractured primary particles.
