Vertical/Horizontal Centrifuges

GTJones has a wealth of experience in the field of centrifuge repairs and enhancements, having serviced many vertical (disc-stack) and horizontal (decanter) centrifuges for the local kaolin companies over the past 10 years, performing not only repairs but also a program of improvements to enhance performance and prolong service life. Typical enhancements we have incorporated include:

Restoration of scroll (conveyer screw)/Bowl clearances to maximise efficiency.

Hard facing of scroll (conveyer screw) flights and other high wear areas.

Replacement of broken scroll (conveyer screw) flights or vanes.

Retiling of scroll (conveyer screw) flights with either carbide or ceramic tiles.

Design of ceramic coated sleeves for seal diameters improving service life significantly.

Ceramic or Belzona coating of vertical centrifuge bowls to prolong life.

Dynamic balancing (typically to G1).

Geometric checking and correction of shafts, Spigot diameters, Scrolls (conveyer screw) and Bowls, increasing running efficiency and bearing life.

As well as our standard repair enhancement procedures in 2006 we were contracted to complete a large project for a global minerals company to refurbish and upgrade 4 large decanter type centrifuges of the old international combustion type “Dynocone” design for their new refinery. This involved the design and manufacture of 4 new scrolls (conveyer screws) and overhead motor mounting frames.
