China WPL Series Horizontal Disc Dryer - Efficient Sludge Drying Technology from Reliable Suppliers & Factory
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 to work together for efficient heat transfer and sludge drying.
How is the heat transferred to the sludge?
The sludge is indirectly heated. The heat transfer occurs through the jacket, the hollow shaft, and the hollow disc welded on the shaft as the steam circulates inside them.
What makes this disc dryer highly steam efficient?
Since the dryer utilizes steam for indirect heating and features an outer jacketed wall, there is no significant amount of air flow carrying heat away. This design maximizes steam utilization efficiency.
Does the drying process cause severe secondary pollution?
No. Since the steam does not come into direct contact with the sludge, the volume of insoluble gas remains low. This gas can be safely incinerated in the furnace, resulting in minimal secondary pollution.
Why is this dryer suitable for domestic sludge treatment?
It operates at a low rotational speed with no tangential force between the rotor and the sludge. This results in minimal wear, low maintenance costs, a long operational lifespan, and low overall power consumption.
What are the post-drying disposal options for the sludge?
After the crushing and stirring process, the sludge is reduced to uniform particles. This consistency is highly beneficial for subsequent disposal methods, including incineration, land application, or use in building materials.
