From limestone to burnt lime

Fully automatic, controlled from a supervision room, the stones get from the silos to the shaft kiln. Using burner lances, the stones are heated to 1100 °C in the kiln's burning zone where carbon dioxide is released, and the limestone turns to burnt lime. Within 24 hours, up to 200 tonnes of highly reactive quicklime can be produced.
More than one third of the burnt lime is comminuted in a jaw crusher, and after having been classified in a screening unit, the lime - now called nekafer - gets to the rail or road dispatch.
