The main component of limestone is calcium carbonate (CaCO3), which can be directly processed into stone and fired into quicklime. It has a long history as our usual building material. In modern industry, limestone is the main raw material for the manufacture of cement, lime and calcium carbide. It is an indispensable flux limestone in the metallurgical industry. After being ground, limestone is widely used in the manufacture of paper, rubber, paint, coating, medicine, cosmetics, feed, sealing, bonding, polishing and other products.

Limestone crushing production process

The limestone crushing production process mainly includes four processes: feeding, crushing, screening and conveying.

1. Feeding process: The vibrating feeder is commonly used in the industry at present, which feeds the stones in the raw material bin into the primary crushing equipment uniformly and continuously, and the performance of the whole process is stable and reliable.

2. Crushing process: This process is divided into coarse crushing and medium and fine crushing. Jaw crusher is coarse crushing equipment, impact crusher and cone crusher are mainly used for medium and fine crushing. However, the softness of the crushed materials of the two is different, and the user should choose and configure according to the production situation.

3. Screening process: After crushing and sand making, the stone needs to be screened. This process can effectively control the size of the finished product and screen out the sand and gravel required by different industries.

4. Conveying process: The belt conveyor runs through almost the entire technological process and is responsible for the conveying of materials in each process. It is an indispensable supporting equipment in the limestone crushing production line.

Limestone crushing equipment

Limestone is crushed into stones of various specifications (05, 12, 13), and the crushing equipment is mainly divided into three categories: coarse crushing, medium crushing and fine crushing. 

For coarse crushing, jaw crusher is generally used. Since limestone is a soft rock and its hardness is not high, the impact crusher is generally selected for medium crushing. 

For finely crushed sand, you can choose an impact sand making machine, and if you need to grind, you can also choose a Raymond mill.

In addition, if you have relatively small requirements for the output of the production line and the requirements for the particle size of the stones are not so high, the hammer crusher is also a good choice. A variety of functions.
