How it works and what it targets
Mechanical shaping uses controlled impact, friction and separation to alter morphology and size distribution. Graphite commonly requires a balance of roundness, tap density and yield; mica or wollastonite may instead need plate-like or needle-like structure preserved. Shaping does not mean every material should become spherical.
Reference process steps
- 1Establish feed morphology, size and end use, then define the target shape.
- 2Adjust shaping intensity, time and classification, separating generated fines.
- 3Evaluate morphology, density, size distribution and stream yields together.
Configuration and operating conditions
Graphite and coke feeds
Natural graphite, synthetic graphite, green coke and calcined coke have different structures and require separate shaping and dedusting conditions. Similar feed names do not imply the same yield or functional performance.
Morphology and purity
Evaluation can include microscopy, circularity/sphericity, aspect ratio, tap density and contact wear. Particle size or a single micrograph alone cannot establish shaping performance.
Information needed for selection
Provide source and processing history, microscopy, size/morphology/tap-density targets, intended use of fines, impurity limits and capacity.
Discuss selection inputsTrial and acceptance considerations
Pair size, morphology, tap density and mass balance for the same sample, recording intensity and residence conditions. Historical results are not guarantees for new feeds.
