China Suppliers Factory WPL Series Horizontal Disc Dryer for Efficient Sludge Thermal Drying Technology
Applications
The dryer is mainly composed of a jacket, a single axis rotor, and a transmission device. The sludge is indirectly heated and dried by heat transfer through the jacket, hollow shaft, and hollow disc welded on the shaft. The disc does not cut the sludge, but instead stirs the sludge through the action of the pushing mixer at the edge of the disc, constantly updating the drying surface to achieve the purpose of drying.
Features
- The cylindrical body of the dryer is a jacket type structure, and the mixing shaft and disc are hollow with steam circulation, resulting in a very large heating area. The body can be miniaturized and the drying effect is good.
- Due to the use of steam for indirect heating and the installation of a jacket on the outer wall, there is no significant amount of air carrying away heat, resulting in high steam utilization efficiency.
- Steam does not come into contact with sludge, has a low amount of insoluble gas, can be incinerated in the furnace, and has minimal secondary pollution.
- After being crushed and stirred, the sludge becomes uniform particles, which is conducive to further disposal (incineration, land use, building materials, etc.).
- Low rotational speed, no tangential force between the rotor and sludge, resulting in minimal wear, low maintenance, long lifespan, and low power consumption, making it more suitable for domestic sludge.

Frequently Asked Questions
What are the main components of the disc dryer?
The dryer is mainly composed of a jacket, a single axis rotor, and a transmission device designed for efficient sludge drying.
How does the sludge drying process work?
Sludge is indirectly heated by heat transfer through the jacket, hollow shaft, and hollow disc welded on the shaft. The pushing mixer at the edge of the disc stirs the sludge to constantly update the drying surface.
Why is this disc dryer highly efficient in steam utilization?
By utilizing indirect steam heating and incorporating a jacket on the outer wall, there is no significant air flow carrying away heat, resulting in exceptionally high steam utilization efficiency.
Does the disc dryer cause significant secondary pollution?
No. Since steam does not directly contact the sludge, there is a very low volume of insoluble gas. This gas can be incinerated in the furnace, keeping secondary pollution to a absolute minimum.
What is the advantage of the low rotational speed design?
The low rotational speed eliminates tangential force between the rotor and the sludge. This results in minimal mechanical wear, low maintenance costs, an extended lifespan, and low overall power consumption.
What are the final disposal options for the dried sludge?
Once crushed and stirred, the sludge is reduced to uniform particles. This makes it highly suitable for further disposal methods such as incineration, land use, or building materials.
