Particle size analysers support toner
production
Latest information from the Toshiba plant in Dieppe details the company's experience with Malvern's Insitec analysers and highlights the value of on-line particle size measurement in toner production
The Insitec system from Malvern Instruments is a fully automated on-line laser diffraction-based analyzer Toshiba's adoption of this on-line technology has delivered a throughput increase of 1%, a reduction in over-grinding, steadier mill operation and a significant decrease in the amount of operator time dedicated to routine analysis

The process stream being analysed is a hot, viscous, highly concentrated, pressurised suspension which contains particles that are less than 200microns in diameter
Two Insitec systems operate at Toshiba Dieppe, and a third is planned.
The trend within the toner industry is towards products with a smaller particle size.
This is driving the need for increasingly tight control of the industry's energy-intensive milling processes.
It is also making conventional off-line analytical techniques that involve sample dispersion, such as the Coulter counter, more time-consuming.
The Insitec is a well-established robust particle sizing solution for both wet and dry processes.
At its heart lies powerful laser diffraction technology developed and refined by Malvern Instruments over the last 30 years.
Sampling and dispersion form an integral part of the Insitec package, which provides a reliable, proven industrially relevant option for sectors as diverse as powder coatings manufacture and cement production. Request a free brochure from Malvern Instruments ...
