CAMSIZER P4 - Particle Size and Shape Analyzer by Microtrac MRB

"This product covers a very important area in materials analysis. Measurements are simple to make and it offers the possibility of expansion. A system like this can perform a large amount of measurements and, in the environmental sector, cover important market niches, such as working on the quantification of polluting particles (e.g. asbestos) in soils."

"My company moved a CAMSIZER P4 and went about recommissioning it for our use. After resolving a few technical issues, we went about the task of correlating the results to those from a set of sieves which we were replacing. Our initial work resulted in a poor correlation to our existing results. To begin our trouble-shooting process, Retsch Technology remotely reviewed our measurement routines and result data by remote access using Team Viewer software. This confirmed the correctness of the CAMSIZER P4 results which were being generated. Having eliminated the CAMSIZER as the source of our problem, we then began a methodical examination. The sieving data was re-run and then compared to the CAMSIZER results in the CAMSIZER software. This comparison showed a reasonably close correlation with a maximum difference of <1.103%. Retsch Technology decided that a better fit could be achieved and the CAMSIZER software showed us how to do it. The two points which were cause for concern were the 40 mesh and the 25 mesh results (see below). In order to further investigate this, both sieves were subjected to additional vibratory energy, in this case, hand shaking. The result in both cases was additional material passing through the sieve of interest. When this amount was subtracted from the sieve of interest and was added to the next smaller sieve, the results fell right in line with the expected results from the CAMSIZER. In these experiments, the maximum difference was < 0.641%. Thus, the problem was identified to be the overloading of the individual sieves and sticking of near mesh grains to the wire mesh. I am truly amazed by the CAMSIZER’s ability to accurately measure the material. Not only can it accurately measure the material consistently, it can even tell you where your issue is, by the graphs it can produce. The CAMSIZER is truly an amazing machine and amazingly accurate. I highly recommend that all labs purchase a CAMSIZER if you want a very accurate world class measurement system for your COA’s. "
