Liuneng Technology Research Institute

Aerodynamics and gas–solid flow connect equipment geometry, flow fields and powder processing behaviour.

Research areas

Research covers jet and mechanical grinding, air classification, dust collection and pneumatic conveying. Particle forces, collisions, dispersion and separation are studied to match equipment structures to material behaviour.

Collaborative development

The institute was formed with Southwest University of Science and Technology, drawing on professors, researchers and doctoral specialists. New-material work can align processing goals, measurement methods and equipment trials.

Numerical simulation

Fluid-dynamics tools including FLUENT are used to study gas–solid flow and compare grinding and classifier geometry with operating conditions. Simulation supports design alongside practical material trials.

Laboratory and analytical capabilities

Choose measurements around the material's application and processing targets, with sample identity and test methods recorded together.

Particle size distribution

Laser particle size analysis compares feed and processed powders. D10, D50, D90 and oversize targets need to be specified with dispersion and measurement conditions.

Particle morphology

Microscopy and scanning electron microscopy help compare particle shape, agglomeration and surface features when assessing deagglomeration, shaping and grinding.

Specific surface area

Surface-area analysis supplements size and surface assessment. Pretreatment and measurement conditions must be comparable across samples.

Tapped density

Tapped-density measurement helps assess powder packing behaviour for filling and processing applications, alongside particle size and morphology.

Moisture

Moisture analysis informs feed handling, agglomeration, collection, trace-moisture removal, drying and storage considerations.

Combined assessment

Tests can be combined around the project objective. Report contents, methods, sample retention and any third-party testing are agreed before the trial.

From material trials to scale-up

Identify the feed and targets before testing candidate process routes.

1 · Define the brief

Provide material identity, composition, feed size, moisture, target size and throughput, together with purity, morphology or temperature requirements, measurement methods and material safety information.

2 · Agree trial conditions

Engineers review configuration, sample quantity, packaging, shipping and cleaning needs, then agree operating comparisons and assessment methods. Confirm sample receipt arrangements before shipping.

3 · Process and sample

Grinding, deagglomeration, classification or shaping is tested under agreed conditions. Feed details, operating settings and sample identifiers support comparisons between configurations.

4 · Measure and review

Compare feed, product and fractions to understand oversize, recovery, wear or agglomeration, and identify adjustments for the next stage.

5 · Evaluate scale-up

Continuous operation, throughput, utilities, collection and site layout inform the production design. Laboratory results are not automatically contractual performance values for a production line.

New-material collaboration and research records

Development can begin with a specific question about size distribution, contamination or particle shape.

Collaboration scope

Small-sample validation, process comparisons, equipment adaptation and OEM trials can be discussed. Sample use, records, intellectual property and confidentiality arrangements are agreed before work starts.

Research documentation

The institute has participated in research projects and patent and publication work. Relevant public project, patent or certificate documentation can be requested for a specific technology area.
