50-80 t/h Limestone Crushing Plant

The limestone crushing plant is designed to process limestone, a sedimentary rock primarily composed of calcium carbonate, into various sizes for different applications in industries such as construction, agriculture, and manufacturing.

This plant has a capacity of 50 to 80 tons per hour, making it suitable for medium-scale operations.
 

The crushing line mainly consists of the following parts:

1. Vibrating Feeder: The process begins with a vibrating feeder that delivers the limestone rocks uniformly into the jaw crusher.
2. Jaw Crusher: The primary crusher in this plant is a jaw crusher, which breaks down the limestone rocks into smaller, manageable sizes. It has a high crushing ratio and is capable of handling large feed sizes. The recommended machine model here is PE500*750
3. Impact Crusher: Depending on the specific requirements, an impact crusher may be incorporated into the system to further reduce the size of the limestone aggregates. The recommended machine model here is PF1010
4. Vibrating Screen: After the crushing process, the limestone aggregates are screened to separate different sizes. The vibrating screen ensures that only the desired sizes are sent for further processing, while oversized materials are returned to the crusher for re-crushing.
5. Conveyor Belts: Conveyor belts are used to transport the crushed limestone from one stage of the process to another. They ensure smooth and efficient material handling throughout the plant.
6. Dust Control System: To maintain a clean and safe working environment, a dust control system is installed to suppress the dust generated during the crushing and screening process.
7. Control System: The entire plant is equipped with a control system that monitors and regulates the operation of each component, ensuring optimal performance and efficiency.

Jaw crusher

1. Jaw Crusher: This is a widely used primary crushing machine in limestone crushing plants. Jaw crushers operate by compressing rock between a fixed jaw and a moving jaw. The material is fed into the top of the jaw crusher and is crushed between the jaws as it moves downwards through the crushing chamber. Jaw crushers are known for their high reliability, simple structure, and relatively low operating costs. They are suitable for primary crushing of hard and abrasive materials like limestone.

Impact Crusher

1. Impact Crusher: Impact crushers are also used as secondary crushers in limestone crushing plants. They operate by striking the material with hammers or blow bars attached to a rotor, causing it to break along its natural cleavage lines. Impact crushers are known for their high reduction ratios and are capable of producing cubical-shaped aggregates. They are generally more economical to operate compared to cone crushers.
