Doubleroll crushers are able to crush more finely than singleroll crushers, because they are designed with teeth that mesh together rather than rotating past a smooth plate. They can reduce coal to as little as ¼ inch ( cm) topsize, although they are more commonly operated close to 2 inches (5 cm).
Coal breakers and crushers There are a number of breaking devices commonly used for reducing the top size of "RunofMine" coal. These vary in their capacity and ability to deal with very hard, soft, or sticky coals, and in some cases they can also reject coarse rock that contaminates the coal. Rotary breakers
