The patented W.S. Tyler CPA measuring process is used to analyze the grain sizes and shapes of dry and non-agglomerating particles of bulk materials in the range from 10μm to 400mm. The robust technology is virtually maintenance free; therefore, it is absolutely fail-safe and works reliably, even under extreme conditions. The CPA technology can be used to analyze coarse and fine material, such as gravel, sand, coal, plastic granules, wood chippings, chemical and pharmaceutical products, fertilizers, and much more.
