The W.S. Tyler Computerized Particle Analyzer 4 Conveyor is a dynamic image analysis system designed for particle sizes ranging from 63 microns to 50mm.

All W.S. Tyler CPA units feature real-time function and work with a single line-scan camera; therefore, every particle in the grain size range can be measured and the results used in size and shape analysis. Double detection due to individual images overlapping is ruled out, as are partial ranges and improper measurements of truncated particles. In addition, the real-time function also enables all CPA units to be used as particle counting devices

Each particle at a glance.

The CpaServ software deployed in the W.S. Tyler CPA systems is easy-to-use, responsive, and runs under most Windows operating systems. Owing to the software, a wide range of particle specifications can be analyzed. The CPA’s individual particle memory allows different grain shape values to be evaluated for every particle measured and statistical means to be determined in freely selectable grain size classes.

Each particle is fully scaled and presented in the particle list. The details regarding particular grain sizes and shapes are stored and can be used for further analyses. Input data errors can be minimized given the software’s ability to cut and paste into documents or tables, such as Excel. Furthermore, multifarious options for filtration enable a customized presentation of results.

What is the W.S. Tyler CPA?

In the field of conventional particle analysis, W.S. Tyler, alongside parent company Haver & Boecker, has been a market-leading manufacturer of test sieve shakers for decades. As a result, in the early 90s, our accrued expertise and pioneering spirit provided the ideal platform for exploring the next frontier in particle analysis: integration of powerful computing technology.

Our wide product range, consisting of future-oriented, expandable modular units and systems, guarantees flexible solutions for all applications. Our photo-optical systems have proven their worth with hundreds of minerals in various sectors. Whether in the form of standardized laboratory/online units or customized industrial units, from pharmaceuticals, food, and non-metallic minerals to the plastics and fertilizer industries, W.S. Tyler delivers.

How CPA works

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.

W.S. Tyler CPA systems are based upon energy-saving, low-maintenance technology that minimize operating costs. They are ready to connect to a PLC control system in their standard configuration and can also be integrated into online processes at a later date without modification. The results produced by the device are comparable with a conventional sieve analysis, but offer several decisive advantages, including high reproducibility of measuring results, enormous time saving, additional information related to grain shapes, and the number of particles.
