Malvern Insitec particle size analyzers support Toshiba toner production
The
latest information from the Toshiba plant in Dieppe details the
company’s experience with Malvern’s Insitec analyzers 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. 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. http://www.malvern.com/
