<\/a><\/figure>\n\n\n\n<\/a><\/figure>\n<\/figure>\n\n\n\n\u201cAs we demonstrated our expertise and added value, the mine invited us to assess other transfer points where they were experiencing operational challenges,\u201d Archer explains. \u201cThese included the jaw crusher feed chute and the apron feeder discharge chute, both of which handle large run-of-mine ore lumps up to 800\u20131200 mm.\u201d<\/p>\n\n\n\n
Material arriving at the jaw crusher was also moving at high velocity, leading to excessive wear and damage. After analysing the application, Weba Chute Systems proposed a solution.<\/p>\n\n\n\n
\u201cWe replaced the existing jaw crusher feed chute with one of our custom-engineered designs incorporating swing doors to absorb the energy of incoming material, reducing impact and wear,\u201d says Archer. \u201cWe later implemented the same swing door concept in the apron feeder discharge chute. Today, swing doors are also installed on the vibrating grizzly feeder and directly above the crusher \u2013 all effectively controlling flow and reducing wear.\u201d<\/p>\n\n\n\n Weba Chute Systems went a step further by modifying the impact bed on the grizzly feeder. By raising the impact bed, incoming material begins to slow down before reaching the first swing door.<\/p>\n\n\n\n \u201cThese innovations made a significant difference, particularly in managing the impact from oversized lumps,\u201d he notes. \u201cWe also finetuned door weights to optimise material flow, prevent build-up and reduce the risk of blockages.\u201d<\/p>\n\n\n\n The mine also commissioned Weba Chute Systems to install a SAG mill discharge chute, which Archer reports has been operating \u201clike clockwork\u201d since commissioning. This chute accommodates a 4 m transfer height, tapering from a 2.4 m wide screen opening to a 600 mm wide conveyor belt.<\/p>\n\n\n\n \u201cThe success of this bespoke unit lies in the careful placement of dead boxes within the chute to promote material-on-material flow,\u201d he explains. \u201cIt was equally important to manage the discharge speed to avoid damaging the conveyor belt.\u201d<\/p>\n\n\n\n Archer credits the Gamsberg plant\u2019s professional and solution-oriented culture where the emphasis is on resolving root causes rather than symptoms and on working collaboratively with trusted suppliers to overcome technical challenges.<\/p>\n","protected":false},"excerpt":{"rendered":" On the strength of its first transfer chute installation at Vedanta International Zinc\u2019s Gamsberg mine in the Northern Cape, Weba Chute Systems has steadily expanded its footprint at this dynamic operation.
