- Gondwanaland Diamonds South Africa MD Gavin Armstrong says the company's Armstrong vibratory screen and conveyor belt system can cut up to a quarter, or an eight, of a mine's current vibratory screen and conveyor belt electricity usage (07/04/'08) Cameraperson: Danie de Beer, Editing: Darlene Creamer (5.36 MB)
The system was developed to be a cost and space effective option, he said in an interview with Mining Weekly.
The Armstrong screens were lighter than conventional screens, had a low profile and could be placed in confined spaces.
The Armstrong conveyor belt, which transports the raw materials to the vibratory screen, was a new concept that completely runs in a pipe protecting the belt and the material transported on the belt from natures elements, he said.
"The belt is easy to replace. By just removing the pulley, the belt can be removed and replaced within ten minutes."
The Armstrong vibratory screen and conveyor belt has been in production for three years and have been used in the diamond mining industry, but can be adapted for other mining industries as well.
