Dual Camera System is Part of Reliable Particle Shape Analyser
Addressing the need to detect differences in the particle shape of different charges, the CAMSIZER® from Retsch Technology GmbH (Haan, Germany) analyses the particle size and shape of dry bulk materials in a size range from 30µm to 30mm. With its unique, patented two-camera system it records up to 10,000 particles per second, with what the company claims is an unrivalled dynamic size range. It reliably detects defective or broken particles as well as differences in the particle shape, such as agglomerations.
The following shape parameters can be analysed:
• Elongation; Aspect- or Width-/Length-Ratio
• Convexity
• Roundness
• SymmetryRetsch says that the CAMSIZER® delivers convenient, reliable and fast particle analysis online, at-line or in the laboratory.
The measurement results are evaluated and displayed in real time, with the average measurement time being less than 3 minutes. A highly interesting feature is the single frame analysis together with the automated image recording. The particle size and shape parameters of manually selected, individual particles can be displayed and compared. This allows the user to find reliable threshold values to distinguish good and bad particles automatically and reproducibly, thus ensuring a consistent product quality.
Retsch Technology is a leading supplier in the market for optical particle measurement. The product range includes optical systems for measuring the particle size distribution of dispersions, powders and granulates as well as wet measurement of particles in suspensions, emulsions and colloids.
