Crushing & Screening Reference Manuals

Seeking Photos

As members would be aware the CMPA has been working with Box Hill Institute of TAFE on training materials.

We are now drafting the service and maintain units for crushers, screens, conveyors, bins, feeders and hoppers.

We need your help—do you have or can you take any of the following photos? Alternative, can we take some photo onsite? If you are able to assist, please contact the Secretariat.
