January 11, 2012 - International Innovative Technologies (IIT, Gateshead, UK) is using Malvern Instruments' in-line particle size distribution analysis systems in its specialist low energy milling equipment. IIT specializes in the design and manufacture of a new patented powder milling technology and associated classification equipment. Installation of a Malvern Insitec in-line particle size analyzer as part of the system will enable real-time optimization of particle size distribution in the milled material, accelerating the development of powder milling and processing solutions that combine excellent product quality with low power consumption.   Commenting on the decision to partner with Malvern, Dave Dixon, Technical Sales Manager at IIT, said, “We already have a Malvern Mastersizer 2000 for off-line particle size analysis and it’s worked reliably for years. When we decided to explore the potential of real-time process size and distribution measurement, Malvern was the obvious choice because of our existing relationship and positive experience of the company. Their expertise in this area will be invaluable in helping us to fully exploit on-line analysis to deliver even better milling solutions, faster.” IIT is typically approached by customers targeting a well-defined particle size distribution specification, especially for products such as abrasives, where particle size directly influences product performance. Currently engineers develop a solution with reference to off-line data. A short trial is conducted, samples are taken and analyzed, and the results are used to modify process settings. Real-time particle size analysis will greatly accelerate this optimization step. Commenting on the news on behalf of Malvern, Rob Norris, Business Manager, Process Systems said, “For us it’s essential to really understand the challenges faced by our customers when optimizing milling to cut energy consumption. Working closely with IIT on the development of new milling solutions will help us do this. It will also give us the opportunity to show customers what real-time analysis can deliver by providing access to a facility for education, demonstrations and trials.“ About Malvern Instruments Malvern Instruments is a market leader in measuring performance controlling material properties. These include particle size, particle shape, zeta potential, molecular weight, size and conformation, rheological properties and chemical identification. Malvern delivers the systems, support and expertise that ensure the analytical integrity and productivity needed to drive research, development and manufacturing. About International Innovative Technologies Ltd. Technical advances made by IIT have enabled the development of specialist powder processing technology that replaces traditional milling and particle sizing systems with compact, high output, modular units that are economical to integrate into existing processes and highly versatile in their range of applications. The patented IIT mill is suitable for the fine grinding of a wide range of natural raw materials and industrial products. Importantly, the low energy performance of the new milling systems gives it the potential to convert what may currently be regarded as waste material into commercial products and powders for recycling purposes, including applications in the glass, GRP composites and other hard materials sectors.
