Australian Cement Works Fire
Fire and Rescue New South Wales is reported to have said that the blaze appears to have started in or near a conveyor belt , that then generated large amounts of black smoke as rubber in the system burnt.
Investigations are continuing into the cause of a spectacular fire. In particular, investigators are examining whether a build of heat as a result of friction caused the belt to ignite.
There is still some concern about the stability of a 150 tonne hopper which may have been damaged in the blaze.
