Core has a global customer base, with major projects conducted for clients in every inhabited continent.

Our Equipment

Ultrafine grinding duties for a wide range of sample sizes can be achieved using an M4 IsaMillTM, a laboratory Metprotech mill (with a range of grinding chambers) and an English China Clay mill. hrltesting is accredited by Xstrata Technology to perform IsaMillTM ‘signature’ grinding procedures suitable for IsaMillTM sizing and design purposes.The laboratory has a wide range of particle characterisation tools to assist in the analysis of mineral grinding. These include laboratory Endecotts screens and rotap shakers, Kason screens and screen shaker for larger samples, Malvern laser diffraction particle size analyser and Brookfield and Bohlin viscometers.
