CANTY specializes in the particle size and shape measurement of glass beads manufacturing. ASTM D01.44 is the committee for measuring glass beads and CANTY has been a key member in developing the following 2 standards:
- D7971 – Standard Guide for Measuring Roundness of Glass Spheres Using a Flowing Stream Digital Analyzer
- D7681 – Standard Test Method for Measuring Gradation of Glass Spheres Using a Flowing Stream Digital Image Analyzer
LAB – SOLIDSIZER
The CANTY SolidSizer™ is a vision-based sensor used with the CANTY Vector System image processor for dry particle size measurement in a laboratory environment. The CantyVision™ Software accurately measures multiple aspects of the particles from area / perimeter / minor and major axis / etc. In comparison to a sieve which measures only minor axis the CantyVision™ software can correlate directly to a sieve so the customer does not have to change any QC documents. The SolidSizer™ can correlate within 2% of a sieve. A typical sieve analysis takes anywhere from 20-30 minutes including cleaning and setup for a 70-100 gram sample. On the SolidSizer™ that same sample takes less than 2 minutes. Also multiple screen distributions can be setup to accommodate multiple customers or areas in the process, hence eliminating the need for multiple runs on the same sand for different size distributions. After correlating to current methods of minor axis, customers find benefit in comparing minor axis to major axis and comparing shape factors. Reduce lab time and make sure production samples are not skipped over due to lack of sample time available!

Canty participates in the referenced ASTM subcommittees (D18.26, D32.02 and E29.02) in order to develop useful standards for imaging analyzers. Although the referenced standards are often particular to a type of particle, they can be generalized for use with many types of particles.
ISO9276-6 is widely used to describe shape parameters and provide corresponding formulae for calculation of values.
