Continuous wet and dry milling plants face similar comminution challenges

Continuous wet and dry milling plants face similar comminution challenges in achieving high throughput, consistent milling particle size and efficiency of operation. Wet milling produces finer particle sizes than dry grinding, but dry grinding can eliminate the drying steps needed by wet milling. Malvern Process Systems real-time particle sizing helps:
