The CAMSIZER P4 System – 100% quality control 

The Retsch Technology CAMSIZER P4 has been developed to comprehensively characterise dry, free flowing bulk materials. Whereas traditional sieve analyse can only determine the approximate particle size, the CAMSIZER P4 simultaneously measures both particle size and shape – with much more detail and at a high resolution.

The CAMSIZER P4 is a time and cost-saving alternative whenever continuous quality control of the production process is required. It is also suitable for checking incoming and outgoing goods and generally for measurements of a wide range of different sample materials. The CAMSIZER P4 reliably analyses all size and shape parameters of a great variety of bulk materials and granulates including spherical and irregularly shaped grains and crystals, spray-dried and fluid bed granular materials, pellets and extrudates.

Thanks to the robust construction and a measuring technique that is not sensitive to disturbances, the CAMSIZER P4 is also suitable for operation under challenging industrial conditions.

The CAMSIZER P4 software not only allows for data evaluation in real time but also for the storage of large amounts of image data in the particle library. In additional to the well-known two-dimensional display of results, the CAMSIZER P4 features a new 3D Cloud (3 dimensional graph) which allows for simultaneous display of 3 parameters (for example particle size, aspect ratio and transparency). www.retsch-technology.com.

Application Examples for the CAMSIZER P4

? Quality control of particle size and shape

Glass beads are used for a great variety of applications. They are added, for example, to paints used for road and airport markings to guarantee high retro-reflectivity at night and when the road or airport runway is wet. Size and shape of the glass beads are essential to ensure that the headlight is reflected directly back to the driver or pilot.

The graphic shows the measure of the sphericity of glass beads. At least 80% of the beads need to be spherical to fulfil the high quality standards for retro-reflectivity.

? Determination of length and diameter

Transparent plastic granulate Thanks to a new brighter light source and cameras with higher resolution in the CAMSIZER P4, transparent particles can be captured with excellent contrast, permitting accurate and precise detection. The example shows the length and the diameter analysis of transparent plastic granules.
