Working Principle

The cyclone dryer uses the rotating energy in the flow field of the dryer to make the gas solid mixed swirling, and classifying and drying the material in motion according to the length of the drying time required by the size of the particle.

Thermal air entrainment of wet material is entered by high-speed tangent of the drying chamber at the bottom. Under the action of rotating and centrifugal force, the material rotates in the drying room with the air flow and separates the gas solid. The gas is separated from the center hole into the first stage drying chamber after separation, and the bottom drying chamber is filled with the newly entered materials until the drying room is filled with the air flow to the first grade drying chamber, and the original is repeated. In the process of material filling, the material stays in the continuous filling process and stays in the drying room for a long time. The heat of the wet material in the hot gas flow depends on the heat gas convection heat transfer and the heat radiation from the dry wall jacket. Finally, the material enters the cyclone separator with the air flow and makes the gas solid separation, and the dust is returned by the bag filter. Accept.

The enclosed circulation cyclone drying system developed by the company has also been well applied in drying materials with wet organic solvents.


Process Features

1. With long material drying time. It’s especially applied for drying of low temperatures and heat-sensitive materials.

2. The orifice plate in the dryer has the effect of grading and refluxing, effectively prolonging the drying time of the large granular materials and ensuring the uniform drying quality of the material.

3. Continuous operation, no drying dead angle and vulnerable parts, low requirement for particle size distribution.


Application

This process is suitable for low temperature drying of powdery and granular polymer compounds, or material containing non-volatile crystal water, whose moisture content is organic solvent. (Moisture content of finished products can be effectively controlled from 0.1 to 0.01%)

If supported with other types of drying equipment, application scope can be extended to drying pasty and filter cake material.

Drying product: Polyvinyl chloride, polyethylene, polypropylene, chlorinated polyethylene, polytitanate, polyvinyl alcohol and other resins, polymers and other compounds.


Heating Method

Steam, electricity or heat air furnace heating can be selected as heat source according to factory conditions and allowed temperature of the material.
