Iron ore crushing equipment and process flow mainly include the following steps and corresponding equipment:

1. Raw material preparation: Raw iron ore undergoes rough selection, magnetic separation, and other processes to remove large impurities and obtain small pieces of iron ore suitable for crushing.
2. Preliminary crushing: Send small pieces of iron ore to the jaw crusher or cone crusher for preliminary crushing. The jaw crusher has a large feed particle size, large crushing force, and crushing ratio, and is suitable for the coarse crushing stage. The cone crusher is suitable for secondary crushing. It adopts stacked crushing and has a strong processing capacity, which can improve the crushing efficiency and reduce the fine particle size.

3. Secondary crushing: The initially crushed iron ore is sent to the impact crusher or impact crusher for secondary crushing to crush the iron ore to a suitable size for the next step of processing. Both impact crusher and impact crusher have large crushing capacity and can meet the secondary crushing needs of iron ore.

4. Screening and grading: Screen and grade the crushed iron ore, and send the iron ore that meets the requirements to the production line for processing. Screening and classification equipment includes various types of screening machines, such as vibrating screens, trommel screens, etc.
In addition to the above main equipment, other auxiliary equipment may also be used in the iron ore crushing process, such as belt conveyors, sand pumps, water pumps, and filters. This equipment plays a role in conveying, cleaning, and filtering during the iron ore crushing process, ensuring the smooth progress of the entire process.

In the iron ore crushing process, three-stage closed-circuit crushing is a more modern process suitable for crushing high-hardness iron ore. This process can complete the crushing and partial dissociation of ore, thereby improving the efficiency of subsequent grinding. At the same time, the two-stage and one-close grinding is an efficient grinding process, which can grind the iron ore more fully.

In general, iron ore crushing equipment and process flow is a complex and delicate process that requires the coordinated operation of various equipment and precise process control. Only in this way can the efficient crushing and processing of iron ore be ensured, and high-quality raw materials can be provided for the subsequent production process.
