Antofagasta Minerals has requested Expande to scout for suppliers in the local and international ecosystem that can provide solutions for the challenge “Bolt leak detection and/or elimination in SAG mill.
DESCRIPTION OF CHALLENGE:
At Minera Los Pelambres, its concentrator plant has a SAG-Ball grinding circuit, which continuously presents problems of pulp leaks in its SAG mills. This is probably generated by two factors; liner wear and/or microfractures in the fastening system. Based on experience, these leaks occur in a greater proportion in areas near the pulp discharge grids than in areas near the mill feed.
SCOPE OF THE CHALLENGE:
BACKGROUND – PRIOR SOLUTION ATTEMPTS:
