Dry Roasting Equipment---Tunnel Dryer---The Secondary Dryer

Product Description:

The carrier equipment of the green brick in the secondary dryer is a drying car. The bricks are stacked on the drying car by the racking system. After drying, the drying car is unloaded by the lowering system, and then the bricks are stacked on the kiln car by the racking system. This operation adopts a single layer drying method, which is suitable for raw materials with high moisture content, because each green brick is fully dried, and the drying efficiency is high.

The drying medium is generally provided by the waste heat of the roasting kiln and is supplemented by the burner when the heat is insufficient. The drying room is equipped with a hot air supply system, a moisture exhaust system and a temperature and humidity monitoring system. By monitoring and adjusting the system, the supply air temperature and air volume can be controlled to ensure the drying quality of the bricks.

The structure of the secondary dryer is a multi-channel brick-concrete structure or a multi-channel frame structure without partition walls to adapt to different drying requirements.
