Custom-built screens provide effective solutions
Customised screening and feeding solutions are designed to improve processing performance and tonnage, while reducing total cost of ownership.
A South African diamond operation recently required a customised solution to improve the performance of its degrit screens and Kwatani designed a solution that doubled the feed-rate, explains the company.
The customer was operating a number of multi-slope screens to dewater product between 0.8 mm and 5 mm in size, before it was treated by dense medium separation (DMS). However, the screens were causing a severe carry-over of water onto the conveyor belt to the DMS.
The feed-rate on each screen was limited to about 250 t an hour and Kwatani designed and manufacturing a customised multi-slope screening machine that was able to double the feed-rate to about 500 t an hour, with minimal water carry-over, asserts the company.
In another contract, a customer required a solution for existing underperforming screens and wanted to improve the tonnage throughput by 17%.
Kwatani replaced the screen’s existing gearboxes with two new exciter gearboxes, which was seen as the most cost-effective and timely solution to increasing the screen’s throughput. The replacement gearboxes delivered greater vibration, without exceeding the output torque that the existing motors driving the gearboxes could provide.
The newly optimised operating parameters meant that the material bed depth was lower, so the drive motors drew a lower amperage and reduced the cost of power consumed.
