Process & equipment hub
Translate powder behavior into equipment decisions
Connect material properties, test evidence, equipment principles, and operating windows
Powder-processing equipment cannot be selected from throughput alone. Start with what the unit operation must achieve, define the material state and behaviors that constrain it, then compare equipment principles and operating variables against those requirements.
Core process families
Choose the unit operation before the machine
Each family page is an engineering decision guide. It starts with what the process must achieve, identifies the powder properties and test evidence that constrain the choice, compares equipment principles, and defines the operating and integration questions that must be resolved before scale-up or modification.
Storage & Discharge
Translate flow behavior and wall-friction evidence into flow-pattern, hopper-angle, outlet, liner, and discharge-aid decisions.
Feeding & Dosing
Compare feeder principles and control refill, density variation, aeration, cohesion, pulsation, and delivery-rate accuracy.
Conveying & Transfer
Select pneumatic or mechanical transfer routes by throughput, distance, pressure drop, attrition, segregation, plugging, and receiving conditions.
Mixing & Blending
Match tumble, convective, intensive, batch, or continuous mixing principles to cohesion, segregation, fragility, liquid addition, cleaning, and scale-up.
Size Reduction & Classification
Choose breakage and separation principles by target particle-size distribution, fines, heat sensitivity, shape, contamination, and downstream requirements.
AI & Digital Process Intelligence
Connect laboratory, PAT, imaging, equipment, and process-history data to validated models for monitoring, prediction, anomaly detection, optimization, and control.Broader process areas
Keep adjacent operations visible without forcing extra families
Granulation, drying, dust collection, and filling each introduce distinct equipment and operating decisions. Consider them when selecting or integrating equipment beyond storage, feeding, conveying, mixing, or size reduction.
Granulation & Agglomeration
Wet and dry granulation, compaction, agglomeration, spheronization, binder addition, granule strength, and fines recycle.

Quick comparison
Match the engineering question to the process family
The relevant guide connects the equipment principle to powder behavior, operating conditions, test evidence, scale-up, and upstream or downstream interactions.
| Decision question | Process family | Critical powder inputs | Equipment questions |
|---|---|---|---|
| How do I obtain reliable gravity discharge from storage? | Storage & Discharge | Cohesion, wall friction, bulk density, consolidation, permeability | Mass or funnel flow, hopper angle, outlet size, liner, insert, discharge aid |
| How do I deliver powder at a controlled and repeatable rate? | Feeding & Dosing | Flowability, aeration, density variation, cohesion, refill response | Volumetric or gravimetric, screw geometry, refill strategy, isolation, control response |
| How do I move powder without unacceptable change or interruption? | Conveying & Transfer | Particle size, density, fragility, cohesion, electrostatics, aeration | Pneumatic or mechanical route, velocity, pressure drop, pickup, bends, receiver |
| How do I reach blend uniformity without driving segregation or damage? | Mixing & Blending | Cohesion, size and density contrast, fragility, electrostatics, liquid addition | Tumble, convective, intensive, batch or continuous, residence time, fill level, scale-up |
| How do I reach the target size distribution without excessive fines, heat, or contamination? | Size Reduction & Classification | Breakage behavior, hardness, feed size, heat sensitivity, shape, abrasiveness | Impact, attrition, compression, jet milling, screening, air classification, recycle |
The family narrows the engineering decision. Use the child page to connect equipment principles with the material state, operating window, test evidence, and integration constraints that matter in the application.
Connect the decision
Move between mechanism, evidence, diagnosis, and application
Equipment selection is only one layer. Use the other hubs when the decision depends on the underlying powder behavior, a measurement route, an observed failure, or an industry-specific requirement.
