Basalt, with a Mohs hardness of 5–7 and dense mineral composition, requires specialized crushing equipment. Below are recommended crushers for different processing stages:

‌1. Primary Crushing‌

‌Jaw Crusher‌: Ideal for initial coarse crushing, capable of handling large basalt blocks (up to 1,500 mm in size) and achieving the output of up to 2,000 tons per hour. It produces uniform 40–100 mm fragments for subsequent processing.

 

‌2. Secondary and Fine Crushing‌

‌Cone Crusher‌: Utilizes laminated crushing principles to produce well-shaped particles. Hydraulic protection systems enhance durability and reduce maintenance frequency, making it suitable for medium-to-fine crushing of basalt.

 

‌Multi-Cylinder Hydraulic Cone Crusher‌: Particularly effective for high-hardness materials like basalt, ensuring high crushing efficiency and product quality6.

 

3.‌Fine Crushing and Sand-Making‌

‌Vertical Shaft Impact Crusher/Hammer Crusher‌: Provides high-intensity impact force, suitable for producing fine-grained sand from basalt. These machines outperform roller crushers in handling hard rocks45.

‌Double-Stage Hammer Crusher‌: Specifically designed for high-hardness materials like basalt and granite, offering cost-effective crushing solutions

 

4.Mobile Solutions‌

‌Mobile Crusher‌: Integrated jaw crusher, cone crusher or impact crusher, supports oil-electric hybrid power, suitable for projects with limited site or frequent site transfer, reducing material transportation costs and equipped with dust and noise control systems for environmentally friendly operations

 

5. Key considerations for selection

Material characteristics: The "three-stage" combination of jaw crusher + cone crusher + impact crusher is preferred to fully adapt to the high hardness characteristics of basalt.

Capacity matching: The output of a single jaw crusher can reach 2,000 tons per hour, and the medium and fine crushing efficiency of a cone crusher is more than 30% higher than that of an vertical shaft impact crusher.

Maintenance cost: The life of the wearing parts of a hydraulic cone crusher is 50% longer than that of a traditional model, reducing downtime losses.

Investment budget: The initial cost of mobile equipment is higher, but it can save infrastructure costs and is suitable for short-term or dispersed projects.

 

Summary: Basalt crushing requires a multi-stage linkage solution of "coarse crushing-medium and fine crushing-sand making". Jaw crusher (coarse crushing) → cone crusher (medium and fine crushing) → vertical shaft impact crusher (sand making) is the optimal combination. Although the double-roll crusher can handle basalt, cone crusher and impact crusher are preferred for long-term high-load operations.
