Powders and granules are essential raw materials and intermediates in the manufacture of a wide range of products across different industries, including food, agrochemicals and specialty chemicals. The characteristics of these materials can have a direct influence on their processability and hence on the quality and performance of the resulting product.

CLASSIZER™ ONE answer to the demanding request of a non invasive, continuous, trustable monitoring of powder suspension in fluids. CLASSIZER™ ONE measures the particle size distribution, classifies the constituent material and define the particle aspect ratio of the powders, from product development through to manufacture and QC processes. Moreover, the single particle approach prevents from the use of complicate mathematical inversion methods, and immediately enables to measure non spherical sample with high polydispersity.

The case of quartz

Quartz is a mineral mainly represented by prolate particles, that are particles with the shape of a spheroid generated by rotating an ellipse about its longher axis. CLASSIZER™ ONE analysis of the powder suspension showed a population appreciably broadened, compatible with the expected shapes. Retrieved aspect ratios of calibrated mineral samples are in agreement with expected values. Thanks to EOS innovative techniques and proprietary algorithms, precise particles characterization is obtained also for powder with a shape as far as possible from an ideal sphere.

The case of kaolinite

Kaolinite is a mineral mainly represented by oblate particles, that are particles with the shape of a spheroid generated by rotating an ellipse about its shorter axis. CLASSIZER™ ONE analysis of the powder suspension in water showed a population appreciably broadened, compatible with the expected platelet shapes. Retrieved aspect ratios of calibrated mineral samples are in agreement with expected values. Thanks to EOS innovative techniques and proprietary algorithms, precise particles characterization is obtained also for powder with a shape as far as possible from an ideal sphere.
