When we mention “semi-coke,” we are referring to a high-quality coal product primarily obtained through the combustion of refined coal blocks. Semi-coke plays a significant role in the industrial sector due to its distinctive characteristics, including high fixed carbon content, elevated electrical resistivity, and excellent chemical reactivity. Additionally, it features low ash, aluminum, sulfur, and phosphorus content. These qualities make semi-coke an ideal alternative, gradually replacing traditional metallurgical coke and finding extensive applications in the manufacturing of products such as calcium carbide, ferroalloys, ferrosilicon, and silicon carbide.

In addition to the industrial sector, semi-coke has also demonstrated its unique value in civilian applications. Its environmental characteristics, such as low sulfur, low ash content, and high calorific value, make it an ideal choice for reducing coal combustion-related urban air pollution. Therefore, in today’s environmentally conscious society, semi-coke has received active promotion and application.

The Working Process of the Semi-Coke Rotary Dryer System

The Working Process of the Semi-Coke Rotary Dryer System

During the semi-coke drying process, a series of equipment, led by the semi-coke dryer, is required to complete the drying process.

Firstly, wet semi-coke is unloaded by a forklift into the feeding hopper and then uniformly fed by a feeder machine before being sent to the feeding end by a belt feeder.

Subsequently, the semi-coke flows into the cylinder of the semi-coke rotary dryer through a guide pipe. The heat generated by the combustion furnace of coal powder enters the main machine and comes into contact with the semi-coke under the action of the induced draft fan. Inside the semi-coke rotary dryer drum, the flipping of the baffle plates ensures that the semi-coke is evenly dispersed and fully exposed to hot air, accelerating the process of drying heat and mass transfer.

The semi-coke rotary dryer is equipped with a fall prevention device independently designed by the industrial dryer manufacturer AGICO, effectively reducing the rate of damage to semi-coke during the drying process. As the drum rotates, the material moves to the other end under the action of internal devices in the lan charcoal dryer.

Finally, the material is discharged through the discharge valve at the discharge end and transported to the storage location by a conveyor. The hot air generated by the coal powder combustion furnace needs to be collected from the gas through a cyclone dust collector after passing through the semi-coke dryer. If further reduction of dust content in the exhaust gas is required, it needs to be processed through a bag filter or wet scrubber to achieve environmental protection goals. So far, the semi-coke drying process in the rotary dryer system is complete.
