Limestone Crusher

1. Introduction to Limestone: Global Market and Applications

1.1 Limestone Market Overview

The global limestone market size was valued at $7.99 billion in 2022 and is projected to reach $10.79 billion by 2028 (IMARC Group). Key growth drivers include:

1.2 Major Applications of Limestone

• Construction Industry: 70% of limestone is used as aggregate in concrete and asphalt
• Steel Manufacturing: Essential flux material in blast furnaces
• Environmental Applications: Flue gas desulfurization in power plants
• Chemical Industry: Raw material for cement, lime, and calcium carbonate

2. Limestone Mining and Processing Workflow

2.1 Limestone Mining Methods

2.1.1 Surface Mining Operations

Most limestone is extracted through open-pit mining using these steps:

1. Overburden removal with excavators
2. Drilling and blasting operations
3. Primary fragmentation using hydraulic breakers

2.1.2 Underground Mining Techniques

Used when surface deposits are exhausted or geologically unsuitable:

• Room-and-pillar mining
• Longwall mining for thick deposits

2.2 Limestone Processing Stages

2.2.1 Primary Crushing Stage

Raw limestone (≤1500mm) is reduced to 200-300mm using Liming’s C6X Jaw Crusher featuring:

• Upgraded motor power (160-250kW)
• Welded frame construction
• Adjustable hydraulic discharge opening

2.2.2 Secondary Crushing Stage

Material is further processed to 30-50mm by Liming’s HST Single-Cylinder Hydraulic Cone Crusher with:

• Laminated crushing principle
• Automatic control system
• Dust-proof labyrinth seal

2.2.3 Fine Grinding Stage

For applications requiring powder (80-425 mesh), Liming’s MTW European Grinding Mill offers:

• Curved duct design reducing airflow resistance
• Planetary gear reducer with 20% higher efficiency
• PLC touchscreen control system
