Materials characterisation and assessment

Knowing exactly how a product will behave at any stage of the handling process is crucial. The highly equipped laboratories at The Wolfson Centre for Bulk Solids Handling Technology are able to undertake a very wide range of characterisation measurements. As well as standard measurement apparatus, we also have many bespoke pieces of testing equipment developed in-house to provide information that can’t be obtained from conventional equipment.

Discuss your project requirements with one of our experts – we’ll be happy to offer guidance on the most appropriate measurements for your process.

Characterisation techniques unique to the Wolfson Centre:

Benchmarking flow behaviour for a range of powders from different suppliers
Analysis of temperature variation on discharge behaviour
Measurement of effects of moisture content on handleability
Evaluation of potential for particle breakage through handling systems
Determination of the sensitivity of blends to segregation through simulated process steps

Alongside these specialist activities, more conventional data can also be gathered:

Particle density
Bulk density/compressibility
Size analysis (sieve or laser diffraction)
SEM imaging

Our specialist shear testing equipment is also employed for many types of equipment design exercises throughout the year. The information gained can provide design output for:

Minimum outlet dimension for reliable flow
Convergent wall angles for mass flow discharge
Convergent wall angles for self-draining core flow
Chute angles
Evaluation of choices for wall lining materials
