Salt producers carry out quality control on the mined product during production and on outgoing goods. Some companies use particle measurement systems in the quality lab, some use them at-line or on-line. A basic requirement for most applications is that the salt grains/granules have a defined particle size distribution. The historic technique for measuring the PSD of salt has been sieve analysis. Many salt producing facilities have now switched to dynamic image analysis (the CAMSIZER), which is quicker, more efficient, and provides additional information about the shape of the salt crystals. This application note describes how the CAMSIZER has been successfully used to characterize salt size and shape.
