Another modular coal plant for New Clydesdale colliery

The modular plant division of Bateman Minerals and Industrial has supplied another pump fed modular coal washing plant to Gold Fields of South Africa Limited's New Clydesdale Colliery. The plant is a second stage add-on washery to the modular coal washing plant supplied to the colliery by BATEMAN last year.

The contract was awarded to BATEMAN in February this year and the completed plant was commissioned almost exactly five months later. It is now working to specification.

The second stage plant handles 165 t/hr of clean coal received from the existing plant. The coal is pumped via a mixing box to two dense medium cyclones to separate the 'Low Ash' and 'Cosmos' products. This dense media separation (DMS) technology processes a -40 mm coal to produce a 7 % ash quality product. The low ash product reports to the stockpile conveyor while the Cosmos product reports back to the existing stockpile conveying system.

The plant is about 9 m high and consists of two separate modules, each of which is 10 m long and 4 m wide. The steel and plate-work weighs about 76 tonne. The modules can easily be dismantled, transported and re-assembled elsewhere should the need arise.

The first stage of the New Clydesdale coal washing plant is the single cyclone DMS plant which processes 180 t/hr of -40 mm run-of-mine coal to produce a 10 % ash quality product. BATEMAN won a 1997 Projects and Systems Award from the S.A. Institution of Mechanical Engineers for this plant.
