For the fixed crushing needs of basalt, we carefully recommend the following equipment configuration schemes and detailed selection guides based on your specific rock characteristics and rich industry experience to ensure an efficient, stable and economical production process.
Core equipment layout and selection
Preliminary crushing (coarse crushing)
Equipment selection: Jaw crusher
Function description: Jaw crusher is mainly used for the preliminary crushing of large-sized basalt (maximum feed size up to 1200mm) to reduce it to medium size (40-100mm) in preparation for the subsequent processing stage.
Advantage analysis:
Strong structure: Able to withstand the crushing tasks of high-hardness and high-abrasive basalt.
High crushing efficiency: Able to quickly crush large rocks into suitable medium-sized particles.
Strong durability: Key components are made of high-quality wear-resistant materials to extend service life.
Recommended models:
PE series: such as PE-750×1060 model, its upper processing limit is 630mm, suitable for small and medium-sized production lines.
Large models: such as 1200×1500, with a capacity of up to 400-800 tons/hour, suitable for large production lines.
Medium and fine crushing stage
Equipment selection: Cone crusher
Function description: Cone crusher is responsible for further refining the coarsely crushed basalt material to 10-30mm to meet the requirements of different aggregate specifications.
Advantage analysis:
Laminated crushing technology: Ensure uniform particle shape after crushing and improve product quality.
Long life of wear-resistant parts: Reduce downtime for replacing parts and improve production efficiency.
Hydraulic overload protection function: Effectively protect the equipment from overload damage.
Applicable scenarios: Especially suitable for the crushing of high-hardness basalt, and the operating cost is relatively low, which is an ideal choice for medium and large production lines.
Fine crushing/shaping stage
Equipment selection: Impact crusher or impact sand making machine
Impact crusher: Suitable for engineering projects with high requirements on particle shape, such as highway construction. The high proportion of cubic particles in the finished product meets specific engineering needs.
Impact sand making machine (such as VSI-1145): Through the "stone-on-stone" crushing mechanism, it can achieve the output of round particles with a capacity of more than 500 tons/hour. Suitable for high-standard projects with strict requirements on aggregate shape and particle size distribution.
Alternative solutions and differentiated considerations
Economic and efficient selection
Jaw crusher + impact crusher combination: Although the impact crusher wears faster, the cost is low, which is suitable for small and medium-sized projects or production lines with strict cost control.
Large production line optimization
Three-level configuration (jaw crusher + cone crusher + sand making machine): The sand making machine is used for shaping to ensure that the needle-like content of the finished product is less than 5%, meeting high-standard requirements, such as airport runway construction projects.
Special scene replacement
Double-roller sand making machine: Suitable for small-scale fine crushing operations, with a capacity of about 100 tons/hour, suitable for small-scale production lines or occasions with low particle size requirements.
Double-stage hammer crusher: Suitable for processing water-containing materials, but limited hard rock processing capacity, suitable as an alternative in specific scenarios.
Implementation considerations
Pretreatment stage
Due to the high silicon content and hardness of basalt, a vibrating feeder should be configured to achieve uniform feeding, reduce equipment wear and energy consumption.
Environmental requirements
Fixed production lines need to integrate dust removal and noise reduction systems to ensure environmental friendliness during the production process. Special attention should be paid to the fact that the amount of dust generated by impact crushers is higher than that of cone crushers, and more effective dust removal measures need to be taken.
In summary, for the fixed stone crushing needs of basalt, the equipment configuration solutions and selection guides we provide are designed to ensure an efficient, stable and economical production process. According to your specific needs and project scale, choosing the most suitable equipment combination will bring you the greatest economic and environmental benefits
