Specific Workflow Of Limestone Crushing Line

The limestone crushing line is a systematic processing flow aimed at gradually crushing large limestone raw materials into the required particle size range. The following is the specific workflow of the limestone crushing line:

1. Raw material preparation and feeding

Mining or procurement: Firstly, limestone raw materials are obtained from mining or through market procurement.

Preliminary cleaning: The raw materials may contain impurities such as soil and weeds, which require preliminary cleaning to reduce wear and tear on the crushing equipment and affect the crushing effect.

Feeding: The cleaned raw materials are evenly fed into the feeding port of the crusher through equipment such as vibrating feeders and conveyor belts.

2. Initial crushing

Coarse crushing: Large pieces of limestone first enter the coarse crusher, usually a jaw crusher. The jaw crusher compresses, splits, and bends large limestone blocks into smaller ones through the periodic reciprocating motion of the moving and stationary jaws.

Discharge and transportation: The crushed material is discharged through the discharge port and transported to the next process by conveying equipment (such as a belt conveyor).

3. Medium to fine crushing

Intermediate crushing: Limestone that has been roughly crushed enters an intermediate crusher, such as an impact crusher or a cone crusher. These devices further crush materials into smaller particle sizes through different crushing principles such as impact, compression, shearing, etc.

Fine crushing (if required): Depending on the particle size requirements of the final product, further fine crushing treatment may be necessary. Fine crushers usually have higher crushing efficiency and finer particle size control capabilities.

4. Screening and Grading

Screening: The crushed material enters the vibrating screen for screening. The vibrating screen separates materials by particle size through vibration to obtain products of different specifications.

Grading: According to the needs, the screened materials can be further graded to meet the particle size requirements for different purposes.

5. Finished product output and storage

Finished product output: The screened and graded finished limestone is sent to the finished material pile or directly to the subsequent production process through conveying equipment.

Storage: Finished limestone can be stored in material piles for subsequent use or transportation.

6. Dust removal and environmental protection

Dust removal system: A large amount of dust will be generated during the entire crushing process. In order to protect the environment and workers’ health, a dust removal system needs to be equipped. The dust removal system separates dust from the air by capturing, filtering, and purifying it, and processes it centrally.

Noise control: The crushing equipment generates noise during operation, and measures such as sound insulation and shock absorption need to be taken to reduce the impact of noise on the surrounding environment.

7. Maintenance and Overhaul

Regular inspection: Regularly inspect and maintain crushing equipment, conveying equipment, dust removal systems, etc. to ensure their normal operation and extend their service life.

Troubleshooting: Once a malfunction or abnormal situation is discovered, the machine should be shut down for maintenance in a timely manner to prevent the malfunction from expanding and affecting production progress.

Through the above workflow, the limestone crushing line can efficiently crush large limestone raw materials into products of the required particle size, providing important raw material support for production in various industries.
