Sludge dryer, especially industrial sludge dryer, is a kind of equipment specially used for processing industrial sludge. It removes water from sludge through the drying process to achieve the purpose of volume reduction, weight reduction, stabilization, harmlessness and resource utilization.

Single-channel rotary dryer: suitable for urban sludge drying, with internal installation of depolymerization mechanism, movable grate wing plate, cleaning device and crushing device, which can dry sticky materials that ordinary rotary dryers cannot handle. 

What is the working principle of sludge dryer?

• 1. Sludge feeding: The dried sludge enters the dryer through the chute from the feeder.
• 2. Heat exchange and drying: The sludge exchanges heat with high-temperature hot air or steam in the dryer, and the surface water evaporates. At the same time, the sludge is transported to the discharge port in a spiral trajectory with the rotation of the blade shaft, and continues to be stirred during transportation to make the water seeping out of the sludge continue to evaporate.
• 3. Self-cleaning and crushing: Special devices inside the equipment (such as cleaning devices and crushing devices) can prevent sludge from agglomerating during the drying process, break up the sludge balls that have been formed, and increase the drying speed.
• 4. Discharge: Qualified products that are dried evenly are discharged from the discharge port.

Features and advantages of sludge dryer

• • Energy saving and high efficiency: The sludge dryer adopts indirect heating, which reduces the heat loss carried away by the airflow and improves the heat utilization rate.
• • Small footprint: Stirring and mixing make the materials turn violently to obtain a high heat transfer coefficient, and the footprint and space are very small.
• • Convenient dust recovery: The gas consumption in the drying process is small, the flow rate is low, the amount of dust carried away by the gas is small, and the gas dust is easy to recover after drying.
• • Wide range of applications: It can be used for sludge drying in many fields such as municipal sludge, printing and dyeing sludge, papermaking sludge, electroplating sludge, etc.
• • Continuous production: It can achieve continuous production and improve production efficiency.
