Holcim, a leading cement producer, is using an Insitec on-line particle size analyzer from Malvern Instruments to improve milling efficiency
By continuously monitoring two parallel production lines, the Insitec supplies the data needed to optimize throughput and at the same time produce cement of the highest quality.
"For us, the Insitec is an essential tool for optimizing the performance of the finishing mills and it is of great value to the production teams," said Michel Berger, Chemist - Instrumentation and Environment Specialist.
"It provides continuous particle size data for the material exiting the mills, so that the operators can react quickly and confidently when making control decisions.
We now control the plant extremely closely and transition between different product grades very efficiently.
As a result we have increased throughput and enhanced product quality.' In cement production, particle size is a critical parameter that has a direct impact on product quality.
At Holcim's site in Heming, two identical grinding circuits operate in parallel.
The Insitec samples each one alternately, providing particle size distribution data for each line every 10 minutes.
Laser diffraction techniques are increasingly being used, replacing the traditional technique of Blaine (surface area) measurement.
The Insitec is a robust on-line laser diffraction particle size analyzer that meets requirements for continuous reliable monitoring within the plant environment across a diverse range of manufacturing industries.
