Single roller crushers are used to crush clinker, a raw material that is used to produce cement. The clinker is crushed to a specific size, which is then ground to produce cement. By using a single roller crusher, the cement plant can save space and energy while achieving the desired product quality.
Roll crushers reduce the size of the feed by crushing it between the two rolls, as shown in Fig. 4.7. These consist of two heavy cylinders revolving towards each other. The feed is nipped and pulled downwards through the rolls by friction on the surface.
