First, an overview

The supply of heat for drying can be used in hot air stove, boiling furnace and gasifier, which can be designed according to regional resources, which can effectively reduce production cost.

The heat exchange between the section and the material is full, and the special design of the feeder board is adopted. At the same time, the multi layer heating device is set up in the dryer so that the heat can be fully stopped in the length range of the horizontal dryer, and the heat exchange with the material is fully realized.

The automatic temperature control system can effectively adjust the heating efficiency of various furnaces and ensure energy conservation.

The downstream process is used to dry the material so as to keep the activity of the material unchanged.
