Weir Minerals’ Linatex® Premium Rubber and Linard® 60 have dramatically improved mine life at Kalumbila Minerals Limited’s Sentinel Mine in Zambia, after the Weir Minerals Africa team was asked to provide a coating solution that would last longer long as the product in place.
To date, the Linatex® and Linard® solution has achieved six times the life of the product previously installed at Sentinel Mine. The competing rubber product was no match for the high impact and abrasive nature of the 4,500 tph of mud fed to the crusher discharge chute.
The competitor’s rubber liner failed after two months, resulting in downtime and additional costs for equipment hire and specialist personnel. The remoteness of the site also made it difficult to obtain materials for repairs.
The Weir Minerals Africa team specified a dual layer rubber coating solution. A bottom layer of 30mm Linatex® Premium rubber has been selected to improve shock absorption, due to its resilient properties. Linard® 60 with a thickness of 25 mm was chosen for the top layer, because of its resistance to cutting and tearing of the product going up towards the discharge chute.
Weir Minerals Africa Coating Technical Manager ensured that the order was delivered to the customer site on time. In collaboration with a team from the subsidiary Weir Minerals Zambia, the coating of the parts took place during a scheduled shutdown of the plant.
The combination of 30mm Linatex® Premium Rubber and Linard® 60 lasted a year with little to no signs of wear. This is a 250% improvement in life over the competitive product. As a result, Sentinel Mine experienced reduced downtime and associated cost savings and, with increased plant availability, maintenance personnel were freed up to focus on other problem areas of factory.
Sentinel Mine has a long-standing relationship with Weir Minerals, with a range of Weir Minerals products installed and maintained for many years. With this in mind, the mine was confident that the team would provide an effective solution.
Linatex® Premium Rubber is a proprietary vulcanized natural gum rubber produced by a unique liquid phase compounding process using high quality natural latex. It exhibits exceptional strength, resilience and resistance to cuts and tears, providing superior performance in wet abrasion conditions.
