“It is a major reference for us in a highly significant area of mining activity in Central Africa,” said Ted Cruickshank, project manager at Weba Chute Systems.
Cruickshank explained that the mine called upon Weba due to its expertise in chute design and layout. “Weba Chute Systems believes in accommodating the customer’s project schedule and will pull out all the stops to ensure that deadlines are met, without compromising quality.
“We had to design for ore conditions that were extremely sticky,” he added. The bulk density of the material was 1.7 and the maximum lump size was 375 mm. The belt width was 1,200 mm and the design capacity was 1,500 tph with a belt speed of 1.9 m/s.
“Designing these particular chutes posed a major challenge in that the material has a 60:40 fines ratio. We had to design the transfer points to be able to absorb the impact of the larger sized material and also to alleviate any blockages,” said Cruickshank.
