  • Graphite Sympatec Analysers for Particle Size and Shape

    The final particle size of the graphite required for further processing or direct application is achieved using various grinding processes The size, shape and size distribution of the particles is ultimately determined by the functional properties of the graphite and the quality of the final products Traditional screening analysis and microscopy are often still used to analyse the particle
