DELKOR India revamp of Tata Steel’s 145 m² belt filter: retrofit lessons for plant engineers

30 Second Briefing
DELKOR India has completed a major revamp of Tata Steel’s 145 m² horizontal belt filter at the West Bokaro coal field, originally supplied in 2006, extending the life of one of the steelmaker’s largest filtration assets. The TAKRAF Group business upgraded key components and control elements to current DELKOR standards, improving cake washing and dewatering performance on fine coal. For plant engineers, the project shows the viability of large-scale refurbishment over full replacement for ageing vacuum belt filters in high-throughput coal circuits.

Our Take
Tata Steel’s West Bokaro coal field sits within a coal-heavy slice of our 78 keyword-matched pieces, where most recent items focus on mobile equipment and power (such as XCMG’s diesel-electric trucks), so a large fixed-plant revamp on a 145 m² filter highlights attention shifting back to core processing reliability and water management.
The original 2006 supply date for the TAKRAF/DELKOR horizontal belt filter implies this revamp is occurring at roughly a 20-year lifecycle, which aligns with typical major refurbishment windows for large coal preparation plant equipment and suggests Tata Steel is opting to sweat existing assets rather than replace with new builds.
Compared with other coal-linked coverage like Anglo American’s recent impairments, this investment in West Bokaro process infrastructure signals that integrated steel producers such as Tata Steel may be more inclined to upgrade captive coal operations to secure feed quality rather than divest or downsize them in the near term.
