The limestone sand production line converts limestone into high-quality sand and gravel through four stages of coarse crushing, medium crushing, sand making and screening, which is widely used in construction and other fields. The production line is efficient and automated, which can ensure the quality of the finished product and is a popular investment project in the mining industry.

As a common ore, limestone is mainly composed of calcium carbonate (CaCO₃) with a Mohs hardness of 3, which is a soft rock. It has the characteristics of chemical resistance, acid resistance, and corrosion resistance, and is widely used in many fields such as construction, glass, coatings, desiccants, etc. In order to meet the growing demand for construction and infrastructure, the efficient operation of the limestone sand production line has become an important issue in the mining industry. The following introduces how to convert this precious resource into high-quality sand and gravel materials through the limestone sand production line.

Limestone Crushing Production Line Process

The limestone sand production line mainly includes four stages: coarse crushing, medium crushing, sand making and screening.

Stage 1: Coarse Crushing

After the limestone ore is mined from the mountain, the block material is transported to the silo after blasting. Through the vibrating feeder, the stone is evenly fed into the jaw crusher for preliminary coarse crushing. The jaw crusher can effectively crush large pieces of stone into medium particle size, preparing for subsequent processing.

Second stage: medium crushing

The coarsely crushed stone is screened by the vibrating screen, and the screened medium particles are transported to the impact crusher through the belt conveyor for further medium crushing. The medium crushed stone is screened again by the vibrating screen, and the stone that meets the customer's particle size requirements is sent to the finished material pile, and the stone that does not meet the requirements is returned to the impact crusher for further crushing, forming a closed loop.

Third stage: sand making

The medium crushed stone is transported to the sand making machine through the belt conveyor. The sand making machine further crushes and shapes the stone to produce high-quality sand. According to different needs, you can choose a double-rotor sand making machine, an impact sand making machine or a vertical shaft sand making machine to meet the specific sand making requirements.

Fourth stage: screening

The finely crushed and shaped sand is screened into coarse sand, medium sand and fine sand through a circular vibrating screen. In order to meet the strict requirements for the powder content of sand, a sand washing machine can be equipped after screening. The sand washing machine can effectively remove fine powder from the sand, improve the purity of the sand, and recycle the sewage through the fine sand recovery device, reducing environmental pollution while increasing the sand production output.

Equipment configuration of limestone sand production line

The complete limestone sand production line includes the following main equipment:

Vibrating feeder: responsible for evenly feeding the stone into the crusher cavity.

Jaw crusher: used for preliminary crushing, crushing large pieces of stone into medium particle size.

Impact crusher: used for medium crushing, further crushing medium-sized stone.

Sand making machine: fine crushing, shaping stone, producing high-quality sand.

Circular vibrating screen: used for sand screening, divided into coarse sand, medium sand, fine sand and other specifications.

Sand washing machine (optional): cleans sand, removes fine powder, and improves sand quality.

Conveyor: connects various equipment to ensure smooth material flow.

Centralized electric control system: realizes automatic control and improves production efficiency.

Technical advantages and application prospects

Full set of matching, better quality of finished products: Choosing equipment from Shibang Group, such as C6X series jaw crusher, HST single cylinder hydraulic cone crusher, VSI6X series impact crusher, can ensure efficient crushing and high-quality finished product particle shape, meeting engineering standards.

Highly automated, good comprehensive benefits: The highly automated design of the production line improves production efficiency, reduces maintenance costs and production costs, and the quality of finished products is stable, with significant economic benefits.

Both shaping and sand making, mode switching: VSI6X series impact crusher can not only make sand efficiently, but also has shaping function, which simplifies equipment configuration and meets diversified production needs.

Strong pressure resistance, durable and reliable: F5X series vibrating feeder is sturdy in design, can withstand large bin pressure and high load, adapt to harsh initial feeding conditions, and ensure stable operation of the production line.

Conclusion

The limestone sand production line can not only efficiently convert limestone resources, but also meet the strict requirements for sand and gravel materials in high-rise buildings, hydropower stations, concrete mixing stations and other fields. With its short investment recovery period and high economic returns, limestone sand production line is becoming a popular investment project in the mining industry.
