UK: Fairport Engineering has revealed details on its work on Hanson’s 1Mt/yr Purfleet ground granulated blast furnace slag (GGBS) grinding plant. The plant includes two closed circuit ball mills and a vertical roller mill. Fairport Engineering worked on a project to improve the raw material intake facilities at the unit to replace a storage bunker with a new feed hopper and ramp. In the next phase the bunker is likely to be removed and replaced with a second feeding system.

The new system includes a reinforced concrete access ramp that will allow front-end loaders to deposit raw material into a 30t capacity Hardox lined hopper before being metered, at up to 200t/hr, by a vibrating feeder, onto an exiting conveyor belt that feeds the GGBS plant. The entire installation was completed in six weeks.
