Particle Size Distribution in Food Powders

Successful Particle Size Analysis of Dry Powders

A correctly set up dry powder measurement using a laser diffraction particle size analyser is much easier to perform than measurement of wet suspensions. However, incorrect measurement set-up can lead to errors and inconsistencies. This article examines the key steps achieving successful dry to powder measurement. Issues examined include powder flowability and sampling, air pressure and sample ...

Effect of Particle Size on Detergent Powders Flowability and Tabletability

Detergent powders are sometimes processed into compact tablets for cleaning purposes based on the advantage of dosage, minimised dusting and packaging its offers over their powder counterpart. The flow-ability greatly influences handling. The particle size within the powder plays a key role on handling, flow-ability and the strength of the produced compact detergent tablet. The Ariel powder use...

Prediction of effect of fine particle removal on efficiency of a spiral circuit by size-by-size partition curves

Partition curves are widely used to determine the spiral separator efficiency. In this work, the partition curves were used in order to investigate the particle transportation to concentrate and tailing streams. Simulation of fine particle removal using the size-by-size partition curves showed that the recovery of gangue particles to concentrate can decrease 8.7%. It also showed that the recove...

Effect of particle size on the flocculation behaviour of ultra-fine clays in salt solutions

Currently, two commercial plants are operating to produce ~20% of Canada's petroleum requirements from the Athabasca oil sands deposit in Alberta. The hot water extraction process is used to extract the bitumen from this resource. During processing, mechanical dispersion forces cause mobilization of ultra-fine clays into the process water (Kotlyar et al., 1992a, 1993). The resulting slurry is t...
