Introduction to granular activated carbon:

Granular activated carbon is divided into shaped and amorphous particles. It is mainly made of coconut shells, fruit shells and coal, and is refined through a series of production processes. The products are widely used in drinking water, industrial water, brewing, waste gas treatment, decolorization, desiccant, gas purification and other fields. Granular activated carbon uses high-quality anthracite as raw material and is refined and processed using advanced technology. It has the appearance of black amorphous particles; it has a developed pore structure, good adsorption performance, high mechanical strength, easy repeated regeneration, and low cost; it is used for the purification of toxic gases, waste gas treatment, purification of industrial and domestic water, solvent recovery, etc.

Can granular activated carbon particles be dried using a belt dryer?
Yes
‌ Granular activated carbon can be dried using a belt dryer‌. Belt dryer is a common drying equipment suitable for drying granular activated carbon. Specifically, the five-layer belt dryer and multi-layer belt dryer dedicated to granular activated carbon can be used for drying granular activated carbon.

Working principle and application scope of belt dryer:
The belt dryer is mainly composed of air inlet unit, exhaust unit, circulating air unit, mesh belt, steam pipeline and condensation discharge pipeline system, dehumidification system, feeder, transmission mechanism and other components. The material is evenly laid on the mesh belt, which is dragged by the transmission device to move in the dryer, and the hot air passes through the material layer to complete the heat and mass transfer process.. This equipment is suitable for drying powdered, granular, cylindrical and spherical activated carbon, with the characteristics of fast drying speed, high evaporation intensity and good product quality.

Characteristics of granular activated carbon and its drying requirements:
Granular activated carbon is usually made of high-quality anthracite as raw material, and is made through processes such as carbonization and activation. It has the characteristics of developed pore structure, good adsorption performance and high mechanical strength. During the drying process, the drying temperature and humidity need to be controlled to ensure that the quality and performance of the activated carbon are not affected. The belt dryer dries the activated carbon with high-temperature hot air, which can effectively remove moisture and improve drying uniformity and thermal efficiency.

Technical specification:

Note: The amount of evaporated water shown in the picture depends on the drying temperature of the material, the thickness of the paving material and the residence time.
