TAKRAF Africa upgrades its 20 year old dust extraction system at Tronox Namakwa Sands

South Africa (Johannesburg), March 2, 2017 – Key global mining, materials handling, minerals processing and equipment supplier, TAKRAF Africa, has recently refurbished a dust extraction system which the company installed at the Tronox Namakwa Sands Mineral Separation Plant (MSP) at Koekenaap in South Africa’s Western Cape province more than 20 years ago. While the refurbished system has the same capacity as the original system, it now offers significantly increased dust collection efficiencies to meet new and more stringent environmental regulations.

Operating on the West Coast of South Africa, Tronox Namakwa Sands mines and beneficiates heavy minerals to produce titanium dioxide feedstock (chloride and sulphate grades), zircon, rutile and high purity iron products.

TAKRAF Africa’s scope of work covered refurbishing the existing Tenova Reverse Pulse Bagfilter systems, making modifications to optimize the ducting system and equipping the filters with new filter bags.  Handling ilmenite, rutile and zircon dust and reducing the dust load from 15 g/Am3 to less than 20 mg/Am3, the refurbished Tenova Reverse Pulse Bagfilters collect dust from various dust sources in the MSP building via the partially new ducting system. Dust disposal is by means of a new double flap valve below each trough hopper into a dust sealed mobile dust skip.

TAKRAF Africa was responsible for mechanical dismantling and erection to hot commissioning of the system.

The original dust extraction systems were installed in 1995 by the equipment supply division of the then Bateman group of companies before it was acquired by the international Tenova group in 2012. “Such longevity of operation is testimony both to the durability of TAKRAF Africa technologies and to the company’s ability to support its installations over the long term,” says Jimmy Tomlin, Manager: Air Environmental, TAKRAF Africa.

TAKRAF Africa has installed approximately 2,000 reverse bag filters in a range of industries in South Africa. The bag filters can handle flow rates between 0.5 and 100 m3/s, with high collection efficiencies of >99.99 %. The reverse pulse action enables the bag filter to maintain its high efficiency rate for 24 hours a day, even under challenging conditions.
