The effect of roller crusher in crushing basalt depends on the type of equipment, technical configuration and process. As a high hardness rock, basalt has very high requirements on wear resistance and crushing force of the equipment.
1.Assessment of applicability and effect of roll crusher for basalt crushing
Limitations of common roll crusher
Traditional models (e.g. 1010) are designed mainly for medium hardness materials (e.g. limestone, coal gangue), and direct crushing of basalt will lead to rapid wear of roll skins, a surge in maintenance costs, and low crushing efficiency.
Impact or hammer crushers may be more suitable for primary basalt crushing.
Advantages of dedicated hydraulic roll crushers
Fully hydraulic roll crushers optimised for basalt perform significantly better:
Efficient crushing: The double roll high pressure squeezing technology (up to 250MPa) penetrates the basalt structure, increasing crushing efficiency by 30% and reducing energy consumption by 40%.
Precise grain control: hydraulic system adjusts the roll spacing (precision 0.1mm), uniform particle size (3-30mm or 0-5mm), low needles and flakes content, and gradation in line with the standard of construction aggregates.
Wear-resistant and durable: high chrome alloy roller sleeve life of more than 3 years, overload protection system to avoid equipment damage.
Environmental protection and energy saving: closed structure + dust removal device, dust emission <10mg/m3, noise ≤ 85dB.
2.Key Notes
Necessity of pre-treatment: basalt needs to be roughly crushed by jaw crusher (to ≤80mm), and then enter the roller machine for fine crushing, to avoid overloading of the equipment due to direct processing of large raw materials.
Maintenance cost control: choosing the design of replaceable roll surface and regular lubrication, the life of wear-resistant parts can be extended by more than 30%.
Intelligent configuration: Priority is given to models equipped with hydraulic adjustment, real-time monitoring and overload automatic yielding system to guarantee continuous production stability.
Ordinary roll crusher : Not recommended to be directly used for basalt crushing, fast wear and low efficiency.
Specialised hydraulic roll crusher: With the cooperation of pretreatment, it can efficiently crush basalt, with high output quality and low energy consumption, which is the ideal choice for large-scale production.
It is recommended to choose the appropriate model according to the capacity demand (e.g. 80 tonnes per hour choose 1080 roll crusher, 200 tonnes per hour choose 1510 roll crusher), and ensure that it is equipped with wear-resistant roll covers and intelligent control system to optimise long-term benefits.
