Zhengzhou Dingli has had the honor of constructing multiple domestic petroleum coke drying projects. These projects have earned widespread acclaim in the industry for their advanced technical concepts, comprehensive supporting capabilities, high-efficiency and energy-saving environmental protection equipment, as well as after-sales service, and are renowned projects in the field of petroleum coke drying.

The petroleum coke drying system consists of a crusher, a pulverizer, a gas hot air furnace, a three-tier rotary dryer, a cyclone dust collector, a pulse bag filter, conveying equipment, a packaging machine, and a power distribution and operation control device. The material process of petroleum coke is as follows: Petroleum coke with a moisture content of 12-15% is crushed by the crusher to a size smaller than 10 millimeters and then fed into the rotary dryer for subsequent drying. The petroleum coke is continuously picked up and dispersed into the spiral channel of the inner layer of the rotary dryer. Subsequently, the petroleum coke passes through the three-tier rotary dryer (inner, middle, and outer layers), facilitating heat exchange with hot air. The dried petroleum coke is quickly moved under the action of wind and its own gravity and discharged from the rotary dryer, thereby achieving complete drying within the controlled travel range. To achieve the drying effect, the material's humidity is reduced to below 3%, completing the drying process, and then discharged via a screw conveyor. The control system monitors and automatically adjusts operational parameters to ensure the drying capacity of petroleum coke, product quality, and safe and stable operation.
