Roll crushers are another type of secondary stage crushers. They use two or more rotating cylinders for compressing and breaking down the material. The cylinders can be smooth or toothed, based on the different application and type of material. Roller crushers are usually applied for soft materials, for example, coal, clay or soft rocks.
