What crusher is suitable for basalt?

Basalt is a hard rock with Mohs hardness of 5 to 7, featuring high hardness and strong abrasiveness. Its crushing process needs to balance working efficiency, wear resistance and finished particle shape. Based on the characteristics of basalt, Shibang Group designs a professional crushing solution combining jaw crusher, cone crusher and sand making machine. These machines are sturdy, durable and highly efficient, making them ideal equipment for basalt processing.

1. Primary Crushing: PEW European Jaw Crusher

It is the top choice for coarse crushing large basalt raw materials within 1020mm in size.
Built with high-quality steel from Baosteel and integrated cast steel bearing housings, its heavy forged eccentric shaft can withstand compressive strength up to 320Mpa, perfectly suited for crushing hard basalt rock.

The deep V-shaped crushing chamber eliminates dead crushing areas and ensures large crushing ratio, with maximum hourly output reaching 800 tons. Equipped with hydraulic lubrication and wedge adjustment structure, it is easy to operate.

2. Medium & Fine Crushing: HPT Multi-cylinder Hydraulic Cone Crusher

This machine is the core equipment for secondary and fine crushing of basalt materials below 334mm, adopting laminated crushing technology.
Materials get evenly squeezed inside the crushing cavity, which greatly reduces flaky particles and produces cubic finished aggregates with great grain shape, fully meeting standards for highway construction and high-grade aggregate production.

Fitted with specially reinforced wear-resistant liners optimized for abrasive basalt, its wearing parts serve much longer than ordinary crushers and effectively cut down operating costs.
It supports hydraulic cavity clearing and automatic iron removal to ensure safe operation when encountering uncrushable materials. Multiple crushing cavity types are available for flexible switching between medium and fine crushing, with output ranging from 27 tons to 1400 tons per hour.

3. Fine Crushing & Shaping: VSI Vertical Shaft Impact Sand Maker

Adopting rock-on-rock crushing mode, it produces well-graded cubic finished sand with adjustable fineness modulus, which complies with national standard for construction sand.
With optimized internal cavity structure, its hourly output hits 60 to 520 tons, 30% higher than traditional sand making machines. The thin oil lubrication system slows down wear of key spare parts and saves energy consumption.
