Impact Belt Dryer

Impact belt dryer is suitable for drying flaky raw materials such as textiles, tobacco, and plate surface coatings. The impact belt dryer is generally composed of two conveyor belts. The impact belt dryer can be separated into modules for individual operation.

Working Principle of Belt Dryer

Material Feeding
The material enters the feed port of the dryer through the feeding system and is evenly spread on the belt conveyor.

Drying Belt Conveyor
The belt conveyor conveys the dried material into the drying chamber. During the conveying process, the belt conveyor moves continuously to convey the material from the feed end to the discharge end.

Heat Transfer
The drying chamber is usually equipped with a heating device, such as a gas heater or an electric heater. Through the heating device, the hot air in the drying chamber is heated to form a hot air flow. The hot air flow transfers heat to the material through the vents above or below the belt conveyor. During the heat transfer process, the material absorbs heat and evaporates its internal moisture, thereby achieving the drying effect.

Dehumidification
The drying chamber is usually equipped with dehumidification equipment, such as a cooler or a moisture discharge system. Through the dehumidification equipment, the moisture in the drying chamber is cooled and condensed into water, and then discharged out of the dryer to maintain the humidity in the drying chamber.

Discharge
After a certain drying time, the material is taken out of the drying belt and leaves the dryer through the discharge port.
