Question: How to choose equipment for limestone aggregate crushing production line?

Dear Amir,

The main component of limestone is calcium carbonate, which belongs to medium-low hardness rock. Because of its good friability and low abrasiveness, it is widely used in the production of building aggregates. 
 
The common configurations of limestone aggregate crushing production line are:
 
1. Jaw Crusher + Impact Crusher: It is a process widely used at home and abroad. The process is mature and reasonable, the operation rate is high, and the equipment investment is moderate.
 
2. Jaw Crusher + Hammer Crusher: The process is simple, the equipment investment is small, but the operation rate is low, and the powdery material is large. With the wear of the hammer head, the output is greatly reduced.
 
3. Impact Crusehr + Impact Crusher, Hammer Crusher + Hammer Crusher: In China, the process appeared after the primary impact crusher matured, which is characterized by short processes, low power consumption, high operating rate and moderate investment in equipment. However, the size of the secondary crusher inlet is limited, and this model is not suitable for large-sized stones.
 
4. Jaw crusher + cone crusher: This process is generally used for the crushing of medium and high hardness stones. In the past, there were not many applications in limestone aggregate processing. In recent years, cone crusher has been increasingly applied to limestone aggregate crushing production lines due to its high efficiency and large output. .
 
Compared with impact crusher and hammer crusher, cone crusher not only has a large output, but also reduces the wear on wearing parts and has a longer service life. And with the continuous improvement of cone crusher performance and new products emerging, multi-cylinder hydraulic cone crusher uses the principle of lamination and crushing, which also solves the problems of many customers' traditional perceptions of poor aggregate shape, multi-needle shape, etc.
 
Generally speaking, it is desirable to use cone crusher instead of impact crusher and hammer crusher to apply to limestone aggregate crushing production line. Although the initial investment cost is higher, the later maintenance cost will be relatively low. When making equipment selection, based on market factors, product quality, and comprehensive operating costs of the production line, you can select a suitable solution.
