The sampling with Sympatec MIXER is used to collect homogeneous and representative analysis samples from process stages with high mass flow rates of dry, relatively narrowly distributed bulk solids, e.g. during the grinding of cement or anode coke. With the aid of two-stage sampling, it is possible to realise extreme division ratios that extract suitable analysis samples in the range of a few grams from product mass flow rates of over one hundred tonnes per hour for real-time laser granulometry with MYTOS. Sample collection at mass flow rates of up to 400 kg/h are realized in a single step directly with MIXER.

The compact Sympatec SCREW SAMPLER is particularly well suited for dry, powdery products that have restricted flowability on account of adhesive or cohesive properties. Here, the extraction of a meaningful analysis sample – under usually inhomogeneous transport conditions in the downpipe – requires the collection of a highly representative cross-section in the process line.

The compact single-point sampling probes are particularly well suited for dry, disperse products that tend to have a narrow grain size range and flow through the pipe cross-section with a preferably uniform distribution during transport. With an installation height of just 150 mm, they are integrated via a weld-on stud with clamping flange directly in the product-bearing process line. With the RODOS dry dispersion used in the downstream on-line analysis system the necessary vacuum for extracting an analysis sample is generated. Accordingly, the probes can be used in combination with both the MYTOS laser diffraction systems and the PICTOS image analysis systems.

Dynamic sampling with Sympatec TWISTER achieves this equal weighting by scanning the entire pipe cross-section on a spiral path with a constant speed. The sample collected in the process is representative of the entire product stream and is continuously fed to the measurement system for analysis. In combination with the laser diffraction system MYTOS or the image analysis system PICTOS and the integrated RODOS dry dispersion, a fine-tuned system with sampling, dispersion and sensing is formed. It provides real-time determination of meaningful and reliable information about the actual characteristics of particle size or shape in the process.
