Introduction and Overview

At Weba Chute Systems, we pride ourselves on working closely with our clients to ensure that commissions and installations of transfer chutes align with the production schedule of the operation to keep the scheduled downtime to an absolute minimum.

In the platinum sector, we have experience dealing with very abrasive materials such as Merensky platinum ore which has a particle size of –150 mm. In these applications, we give particular care to screen feed areas to use the maximum screening area and minimise the impact the material has on screen decks. The only way to successfully realise this is by controlling the flow of material in the transfer point by considering material size and density, transfer speed, height, and trajectory angles.

Installations in this sector often struggle to cope with the sticky fines material. To address this challenge, we line chutes with ceramic tiles that assist in maintaining proper material flow control. Our custom designs are configured to incorporate the best belt-cleaning arrangement and the ideal belt type and size selection to eliminate spillage and improve productivity.

By being involved in the process from the design stage, we can take mitigating steps to solve problems often associated with transfer points, bringing our extensive experience to the table to avoid having to redesign solutions that do not perform adequately. Under normal operating conditions, our chutes in the platinum sector can last for over a decade, with many installations in the field running effectively long after they reach the 10-year mark.
