Coke crusher/coke mill - Coke crushing process flow

Coke is a solid carbonaceous material derived from coal processing and is commonly used as a fuel and reducing agent in the steel industry. The crushing of coke is an important step in various processes, such as in cokeoven batteries, blast furnaces, and coke calcination. The coke crushing process flow typically involves the following steps:

1. Feedstock Preparation: Prior to crushing, the coke may need to be dried and cleaned to remove any moisture and impurities. This ensures that the coke crusher operates efficiently and that the quality of the coke fines is maintained.

2. Coke Feed: The prepared coke is then feed into the coke crusher. The feed can be in the form of lumps or fines, depending on the desired output size and the subsequent use of the coke.

3. Crushing: The coke crusher, which can be a jaw crusher, cone crusher, impact crusher, or hammer mill, reduces the size of the coke to the desired specifications. The crushing process can be either dry or wet, with dry crushing being more common. In dry crushing, the coke is typically conveyed directly to the crusher. In wet crushing, the coke may be washed with water to remove dust and fines before being conveyed to the crusher.

4. Size Classification: After crushing, the coke is often passed through a screening or classification system to separate it into different sizes. This ensures that the coke meets the specific requirements of the steelmaking process. Over-sized particles may be returned to the crusher for further reduction.

5. Collection and Storage: The crushed coke is then collected and stored in bins or silos until it is transported to the point of use. Dust collectors are used throughout the process to control airborne dust and ensure the safety of the operators and the environment.

6. Utilization: The crushed coke is used in various steelmaking processes. In cokeoven batteries, it is charged into the ovens along with coal to produce coke gas, which is a key component in the production of steel. In blast furnaces, coke serves as a fuel and reducing agent. It is also used in coke calcination to produce calcined coke, which is used in the production of high-quality carbon products.

7. Waste Management: The coke crushing process generates waste materials in the form of dust and fines. These waste materials need to be properly managed to minimize environmental impact. This may involve using dust collectors, water treatment systems, and proper disposal methods for the waste materials.

The coke crushing process flow can be adjusted according to the specific requirements of the application, such as the type of coke, the desired particle size, and the capacity of the production line. The selection of coke crushing equipment will depend on these factors and the efficiency requirements of the process. Proper maintenance and operation of the coke crushers are crucial to ensure the quality of the crushed coke and the efficiency of the overall process.
