Physical Quality of Bulk Fertilisers

This paper highlights problems which were encountered when discharging cargoes of bulk raw materials with crane grabs and examines the first three years operation of an alternative method using a Siwertell bulk discharger. Improvements in off-loading rates that were expected initially have not yet been fully achieved, but dust emission experienced with grabs when discharging potash and, in particular, rock phosphate has been completely eliminated.
