Suppose we have a roll crusher with the following parameters: Using the formula: Capacity = (2.5 * 0.5 * 1 * 0.05) / (2 * 10 * 200) Capacity = 0.0625 / 4000 Capacity = 0.000015625 cubic meters per second. So, the calculated capacity of the roll crusher is approximately 0.000015625 cubic meters per second under the specified conditions.

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.
