Clinker grinding technology in cement manufacturing

Clinker grinding technology is the most energy-intensive process in cement manufacturing. Traditionally, it was treated as "low on technology" and "high on energy" as grinding circuits use more than 60 per cent of total energy consumed and account for most of the manufacturing cost. Since the increasing energy cost started burning the benefits …

Helping to reduce mining industry carbon emissions: A step …

On this basis it is estimated that the steel ball consumption of ball mills in HPGR circuits would be 3.6 million tonnes per year – a saving of 2.9 million tonnes per year compared to SAG–Ball mill circuits. This equates to a reduction in emissions of 6.6 megatonnes of CO 2 per year.
