Colleagues,

I need to ask a favour. I have a research project which is examining the diffusion and attenuation of contaminants in landfill leachate through compacted clays and recycled waste materials over extended timescales. We have a range of clay samples (kindly arranged through contacts on this forum) obtained from coring and waste disposal sites which need to be prepared for the experiments. Specifically, we need to mill 300Kg of these clays (currently in blocky/aggregate form) to a fine powder to prepare column experiments. However, we are struggling to find a suitable ball mill or similar clay grinding apparatus which can be used to reduce the clay samples to powder for this purpose.

If anyone can help us directly or provide the name of a person / organisation (e.g. contractor or company offering this service) we can contact to arrange this, please do get in touch. Many thanks for your help.
