5 · Roller screens are often used for screening of coarse-grained materials. They are suitable for screening soft and medium-hard materials. Its advantage is that it does not block the screen. The disadvantage is that the equipment is bulky, the screening efficiency is low, and the roller wears quickly. 3.

Screening is an important step for dry beneficiation of iron ore. Crushing and screening is typically the first step of the ore beneficiation processes. In the majority of the ores, valuable minerals are normally inter-grown with gangue minerals, so the minerals need to be separated in order to be liberated.
