Mechanical processes have an important role to play in the chemical industry. Wherever raw materials, intermediate products or end products are in powder or bulk form, process steps like comminution, mixing, conveying and analysis become indispensable. From 30 September to 2 October 2014, more than 700 exhibitors from more than 25 countries will again be coming to the Nuremberg exhibition centre to attend POWTECH, the world’s leading trade fair in its field, showing everything the chemical industry needs to handle powders, granulates and bulk materials – including analysis. 
 
Even under laboratory conditions, analyses of such factors as particle size, particle size distribution, particle shape and bulk density are among some of the most arduous tasks. A vast range of optical and mechanical analytical systems are used to characterise powders by size, shape, distribution and concentration. But since chemistry often also needs information about particles’ flow characteristics, molecular weight, viscosity and zeta potential in emulsions and suspensions, analytical equipment becomes a key matter of interest when mechanical processes must be controlled.
 
Almost one out of every three exhibitors at POWTECH offers analytical equipment. That large figure reflects the great importance of analysis in processing powders and bulk solids. More than 200 exhibitors will be offering what may well be the world’s most comprehensive overview of various analytical systems for powders, granulates and bulk solids.
 
Analysis becomes a part of the process
Optimised process management, and of course the pressure to maintain quality at low cost, are the main motivations to provide particle analysis as an actual part of a process, or at least nearby. That need has sparked demand for analytical equipment integrated directly into processes. Only such inline and online systems can improve an understanding of the process and make it possible to provide set points for automation.
 
Direct observation of such characteristics as particle size distribution in powders makes processes much more efficient and faster to monitor and control. Waste is minimised, and employed energy is utilised to the best advantage because such steps as grinding need to be continued only as long as is absolutely necessary.
 
There’s also no need to prepare and transport samples as well. POWTECH 2014 has solutions as well for the stringent requirements of real-time particle analysis, because nearly 40 internationally important exhibitors will be bringing their latest developments in inline and online particle analysis to Nuremberg. That means POWTECH 2014 will be a showcase of innovation. The most important vendors will demonstrate how real-time particle analysis can be used for perfect process and production management – whether in initial testing, process control, or process monitoring.
