Granite Crusher

1. Introduction to Granite: Market Prospects and Applications

Granite, a durable and visually appealing igneous rock, is a cornerstone material in construction, infrastructure, and decorative industries. Its global demand is projected to grow at a CAGR of 4.5% from 2023 to 2030 (Grand View Research), driven by urbanization, sustainable building trends, and infrastructure development. Key applications include:

• Construction: High-rise buildings, bridges, and pavements.
• Monuments and Decor: Countertops, sculptures, and flooring.
• Industrial Use: Railway ballast, aggregate for concrete, and road bases.

Granite’s hardness (6–7 on the Mohs scale) and abrasiveness necessitate specialized equipment for extraction and processing. This article explores granite mining workflows and highlights Liming Heavy Industry’s cutting-edge crushing solutions.

2. Granite Mining and Processing Workflow

2.1 Granite Mining Process

Step 1: Exploration and Geological Survey
Geologists assess granite deposits using core drilling and 3D mapping to determine quality, volume, and extraction feasibility.

Step 2: Drilling and Blasting

• Drilling: Hydraulic drills create blast holes (10–15m depth).
• Blasting: Low-impact explosives fragment granite into manageable blocks.

Step 3: Transportation
Blocks are transported to processing plants via heavy-duty trucks.

2.2 Granite Processing Workflow

Step 1: Primary Crushing
Large granite blocks (≤1500mm) are reduced to 200–300mm pieces using Liming’s C6X Jaw Crusher. This robust equipment features a high-strength frame and optimized crushing cavity for maximum efficiency.

Step 2: Secondary Crushing
The material is further crushed to 40–70mm using Liming’s HPT Multi-Cylinder Hydraulic Cone Crusher, which ensures uniform particle size and low wear costs.

Step 3: Screening and Sorting
Granite aggregates are classified using Liming’s S5X Vibrating Screen, which offers high screening accuracy and durability.

Step 4: Tertiary Crushing and Sand Making
For high-value manufactured sand, Liming’s VSI6X Vertical Shaft Impact Crusher shapes granite into 0–5mm particles with excellent gradation.

Step 5: Washing and Storage
Aggregates are washed to remove dust and stored for distribution.
