The success is due in part to the crushing and grinding effect of the pan grinder rollers. The capacity ranges between a few hundred kilograms and over 40 t/h. The KAHL pan grinder mill achieves all this with minimum energy consumption in combination with silent operation, low space requirement and without aspiration system, cyclone, filter and exhaust air plant.

Ball mills, that are commonly used for finish grinding, have high energy demands, consuming up to 30-42 kWh/t clinker depending on the fineness of the cement. Complete replacement of ball mills by vertical roller mills (VRMs) with an integral separator – as opposed to the use of VRMs as pre-grinding to ball mills – is regarded as a breakthrough.

Grinding energy was approximately 50 per cent of the ball mill and the drying capabilities allowed direct processing of materials of up to 20 per cent moisture content. The main energy issue was the high power consumption of mill fans, with pressure drops of 100mbar not uncommon with high nozzle ring velocities (>70m/s) and internal mill circulating loads of …
