Great Wall Foundries became an official supplier for Metso Minerals for their 7 ft Symons cone crushers.
GW & Metso cooperation started in 2010, when Metso discovered GW’s “Die Casting With Sand Layer” technique, after a few rounds of discussions on technical details, 2 sets of 7 ft crusher plates were made for testing and trials. One set of products were tested using industrial X-Ray machine for internal defects while the other set was sent to a quarry for field trials. GW’s products withstood both tests with flying results; GW became an official supplier to Metso thereafter.
