The Need

Falconbridge in Timmins, Ontario needed a plant to produce paste at a rate of 400 tph, continuously, and to gravity feed stopes at over 5 000 feet underground. This turnkey project included mechanical and electrical installation, start-up and commissioning.

BMH Solution

The slump and density consistency was a priority to feed gravity lines continuously. BMH developed a method of measuring the paste density along with software to control the flow of the paste.
