Discussion
A roller press used in closed circuit with a ball mill for cement grinding
Answer: A
Correct answer: reduces the specific energy consumption of the circuit
The roller press applies compression, which breaks particles far more efficiently than the impact of a tumbling ball charge. Pre-crushing the feed leaves the ball mill much less work per tonne, so the circuit’s energy per tonne falls substantially and its capacity rises.
