The purpose of the Skirt is mainly to reduce the generation of dust and to maintain the load on the conveyor, preventing the material from spilling over the edge at the transfer points.

The suction point of the belt is installed on the chute, which is responsible for directing the flow of contaminated air from the point where the contamination is generated, preventing the escape of particulate matter into the environment.

At the end of the chute, a Hawaiian type rubber curtain is placed to reduce the entry of false air into the system.
