Basalt is very hard and tough to process, but once crushed it produces strong, cube-shaped aggregates with fewer flat or needle-like particles. This makes it ideal for use in construction, highways, and railways.

Crushed basalt can be used as road base or further processed into manufactured sand, a good replacement for natural sand in concrete, mortar, and asphalt.

As natural sand becomes scarce, basalt crushing and sand-making plants offer a reliable solution for the aggregate industry.

Basalt rock crushing process

Large basalt blocks (700–1,000 mm) are usually processed into 0–5 mm manufactured sand and 5–10 mm, 5–20 mm aggregates, which meet the needs of concrete and road construction.

Typical basalt crushing stages: Primary crushing → Secondary / Fine crushing → Sand making & shaping → Screening → Washing

Main equipment at each stage:

Stage	Output size	Core equipment	Notes
Primary crushing	≤150–200 mm	Jaw crusher	Pre-screening helps remove soil
Secondary / fine	≤40 mm	Cone crusher / Impact crusher	Cone preferred for hard basalt; impact for shaping
Sand making	0–5 mm, 5–10 mm	VSI / HVI sand maker	"Rock-on-rock" or "rock-on-iron" deep cavity impeller
Screening	Grading	Vibrating screen	Multi-layer design for better classification
Washing	Clean impurities	Spiral / Wheel sand washer	Adjust fines content to meet standards

Final product sizes and applications

• 0–5 mm: Manufactured sand for concrete, dry-mix mortar, asphalt mix
• 5–10 mm: High-grade road base, permeable concrete
• 10–20 mm: Municipal projects, ready-mix concrete plants
• 20–31.5 mm: Railway ballast, highway base, mass concrete
• >31.5 mm: Returned for re-crushing to ensure proper gradation

Basalt stone crushing production line equipment

1. Jaw crusher (primary crushing)

In the first stage, a jaw crusher is used to crush large basalt rocks into smaller sizes for secondary crushing. The feed particle size is 125 mm–1,200 mm and the production capacity is 1–1,000 t/h.

• Deep crushing chamber for large feed size
• High crushing ratio (up to 8:1), even product size
• Strong welded steel frame for stability
• Special flywheel design reduces vibration
• Wear parts are durable and easy to replace, lowering maintenance costs

2. Cone crusher / impact crusher (medium and fine crushing)

Cone crusher is designed for hard rocks like basalt. It can process basalt raw materials with a particle size of less than 560 mm and has a production capacity of 36–2,181 t/h.

• Lamination crushing increases cubic product shape
• Optimized structure improves efficiency by 5%–15%
• Concave easy to replace, no filling needed
• Full automatic PLC and touch screen control system
• Multi-point hydraulic lubrication and overload protection

The Impact crusher produces better particle shape with fewer needle particles and is cheaper than a cone crusher, but it wears faster when crushing basalt. Its feed particle size is ≤800 mm and its production capacity is 30–800 t/h. Get the latest price

Equipment	Cone crusher	Impact crusher
Suitable for	Hard rock	Medium hardness rock
Product shape	More cubic, uniform	Good shaping, finer output
Needle content	Low	Low to medium
Wear life	Longer	Shorter (high wear on basalt)
Energy use	Lower	Medium
Best use	Main hard rock crushing	Final shaping, fine output

杏吧论坛 engineers advice:

• Choose cone crusher if you need stable quality and low needle content.
• Choose impact crusher if you want better shaping and higher fines.

3. Sand making machine

In the sand-making stage, VSI and HVI sand makers are most common. They can work alone or be combined with mobile plants.

杏吧论坛's sand making machine uses advanced German technology. It can perform both sand making and shaping at the same time. The final basalt sand is cubic, with high bulk density and good particle shape. It handles feed sizes of less than 55 mm, with a capacity of 80–650 t/h.

VSI sand maker and HVI sand maker

• Deep cavity impeller, 30% higher output
• Two working modes: "rock-on-rock" and "rock-on-iron"
• Modular design, easy part replacement (cost down by 30%)
• Double oil pumps with automatic shutoff protection
• Hydraulic opening for easy maintenance

Mobile sand making plant

• Best for multiple sites, flexible and efficient.
• Dual power: diesel & electric
• Compact design, no assembly needed on-site
• Strong steel chassis for rough conditions
• Equipped with dust control for environmental protection

After sand-making, basalt sand is separated into different sizes by a vibrating screen. If clean sand is required, it can be washed with a sand washing machine.

Basalt crushing plants with us (50–200 TPH)

A well-designed basalt crushing process helps reduce both investment and production costs. Different capacities are suitable for small, medium, or large sand-making plants.
