On-line milling particle analysis places high demands on the uptime performance of a particle size analyzer, and all Malvern systems are designed from the outset for process use. The key to their success in comminution processes is the ability to be installed almost anywhere, thanks to strong interfacing capabilities, both to the process and to the control system.

  • Highly robust high speed instruments
  • Hygienic fittings to ensure ease of cleaning between production batches of entire sample path
  • Range of options for use in a diverse range of industries from cement / minerals to pharmaceutical / GAMP4 environments

The particle size and dust loading analyzers are used to both optimize and continually monitor the production of wet and dry particulates from a range of milling processes e.g. ball, hammer, sieve, air-jet. Malvern works with a range of partners who supply mill ingequipment and recommend the use of Malvern analyzers in their comminution processes.

Malvern particle size analyzers optimize and monitor milling processes.

Below is a table outlining the particle analysis solutions available for different comminution processes:
