Abstract. Double roll crushing is a comminution principle that has already been deployed for more than 100 years. It is known for high throughputs of sometimes sticky materials such as overburden. However, its applicability for ore and hard rock processing has been underestimated in recent decades.
Usually the double-roll type of crusher is used as the size reduction unit in urea granulation circuits. This device is constituted by two pairs of rolls that rotate in opposite directions at different speeds. The rolls can be smooth, corrugated or toothed and the distance between them (gap) is a key variable parameter.
