Weir Minerals Africa installs linatex hose Sendelingsdrift Namibia

Weir Minerals Africa has installed a Linatex® 808 hard wall rubber hose with wear indicator system at Namdeb’s Sendelingsdrift treatment plant in Namibia to aid in reducing downtime and operating costs.

Sendelingsdrift was previously having to change out the incumbent competitor’s rubber hoses every four weeks due to excessively high wear rates. In addition to the ongoing downtime, the plant also risked losing concentrate due to the hose failures. As the concentrate media contains diamonds, additional security was required when dealing with hose failures that result in concentrate leakage – adding to the operating costs.

The Weir Minerals Africa after an audit of the site, the team considered all the parameters and proposed a trial of a Linatex 808 rubber hose fitted with a wear indicator system. The proposed solution would be capable of withstanding the slurry flow rate of 84 litres per second with a slurry density of 2,65 t/cu.m.

The wear indicator system installed on the hose would indicate when the hose was nearing the end of its life; no physical inspections would be necessary. In addition, Sendelingsdrift would save the cost of additional security requirements by eliminating premature hose failures.

While the previous competitor hose generally failed after delivering 32,000 t of ore, the trial showed that the Linatex 808 rubber hose surpassed 162,000 t, according to the company.  Designed for dual delivery and suction applications, Linatex 808 rubber hose can be custom manufactured to any size and is available with a range of flange types.
