This depends on the type of cooler used. For a batch cooler, a binder dosing system is already provided, to which the binder control can be connected. For continuous coolers (mixed or fluid bed coolers), a continuous cast-related recipe control can be retrofitted. This dosing is behind the cooler, because otherwise the binder is absorbed by the air stream flowing through. In the batch cooler, the air is switched off at the end of the cycle and then the binder is added.
