Crushing is usually a dry process, while milling is performed with water. The advantage of wet milling is the lower energy input compared to dry milling. Additionally, some chemical reagents can be used to minimize the energy consumption of grinding, because grinding energy is minimum at pH of the point of zero electrical charges of the material surface which is known as Rebinder effect.
The roll speed must be sufficient to prevent stalling, but not so fast that the coal is violently thrown out of the mill. Roll crushers most commonly have either one or two rolls, as shown in Fig. 9.3 Meyers, 1981 Jeffrey, 2011 McLanahan, 2011 Stedman, 2011, although some may use three or even four rolls in a two-stage crushing system ...
