Basic and detailed engineering for the 5,000 ton storage capacity clinker silo, as well as the clinker pneumatic discharge system up to the entry of the 4 day bins. This pneumatic system represents an alternative to the existing mechanical redlers system. The clinker is received from the roaster by 2 bucket elevators which discharge into the Redlers.

A new discharge towards the entrance of clinker Silo 3 was implemented from the discharge of one of the redlers.
