100-150 t/h Basalt Crushing Production Line
The 100-150 ton/hour basalt crushing, process, and production line precisely target the core of medium-to-large-scale sand and gravel aggregate project planning. This is not merely a simple capacity figure, but a systematic engineering project encompassing basalt crushing processes from coarse crushing and medium crushing to shaping and sand making. Its core objective is to process high-hardness, highly abrasive basalt into high-quality aggregates meeting various standards (such as those for construction, roadbeds, and concrete) in an efficient, energy-saving, and economical manner.

I. Overview of Basalt Characteristics and Crushing Challenges
Basalt is an igneous rock with high hardness, high silica content, and high compressive strength, making it an excellent raw material for producing high-quality aggregates. However, it also presents significant challenges to crushing equipment:
• High abrasiveness: Extreme wear and tear on vulnerable parts such as jaw plates, hammers, impact plates, and impellers.
• High hardness: High requirements for the crushing force, structural strength, and power system of the equipment.
• Particle shape requirements: The particle shape and gradation of the final product directly affect the aggregate quality and selling price.
Therefore, a well-designed basalt crushing production line must be built around the concepts of "multi-stage crushing, layered crushing, using crushing instead of grinding, and shaping optimization" to maximize operating costs and product value while ensuring production capacity.

II. Classic Crushing Process Schemes and Advantages
For medium-to-high production capacity requirements of 100-150 tons/hour, we recommend the following two mainstream and efficient basalt crushing process flows:
100-150 t/h Basalt Crushing Production Line
(I) Scheme 1: Jaw Crusher + Cone Crusher + Shaping and Sand Making (Three-stage crushing, recommended)
This is the "golden solution" for processing high-hardness, highly abrasive rocks, especially suitable for basalt crushing.
1. First Stage - Coarse Crushing: A heavy-duty jaw crusher is used. Its powerful crushing force and robust structure make it the first and most reliable barrier for processing large (≤750mm) basalt raw materials. The output can be controlled at around 150-200mm.
2. Second Stage - Medium and Fine Crushing: A hydraulic cone crusher is used. This is the core of this scheme. The cone crusher utilizes the principle of layered crushing, effectively reducing the content of needle-like and flaky particles, and boasts a long service life for wear-resistant parts, making it particularly suitable for continuous crushing of basalt. It can crush materials to below 40-60mm.
3. Third Stage - Shaping and Sand Making: A vertical shaft impact crusher (sand making machine) is used. The material from the cone crusher undergoes "stone-on-stone" or "stone-on-iron" crushing to achieve perfect shaping, improve particle shape, and produce high-quality manufactured sand.
Advantages:
• Wear-resistant and economical: The cone crusher has a significant advantage in handling highly abrasive materials, resulting in low long-term operating costs.
• Excellent particle shape: The produced aggregate has good particle shape and reasonable gradation, resulting in high added value.
• Stable operation: The entire equipment line is mature and reliable, with a low failure rate, ensuring continuous production.
(II) Option Two: Jaw Crusher + Impact Crusher (Secondary Crushing)
This option is suitable for scenarios where basalt has medium hardness or requires particularly high particle shape.
1. First Stage - Coarse Crushing: Jaw crusher is used as well.
2. Second Stage - Medium and Fine Crushing and Shaping: Impact crusher is used. Impact crushers utilize impact energy to crush aggregates, producing three-dimensional, tension-free, and crack-free particles, making them ideal for construction.
Advantages:
• Excellent Particle Shape: The crushing effect of the impact crusher results in excellent appearance of the finished aggregate.
• Simple System: Shorter process, potentially lower investment.
• Flexible Adjustment: The discharge particle size can be flexibly controlled by adjusting the gap between the impact plate and the hammer.
III. Successful Case Sharing
A Large-Scale Green Building Materials Base's 3 Million Tons/Year Basalt Aggregate Project
• Raw Material: Basalt, compressive strength > 200MPa.
• Production Capacity: Designed capacity 140 tons/hour.
• Core Technology: Utilizing the recommended combination of "jaw crusher (PE-750×1060) + single-cylinder hydraulic cone crusher (HST315) + multi-cylinder hydraulic cone crusher (HPT300) + VSI6X1263 sand making machine," the system achieves four-stage crushing with refined control.
• Operational Results: Since its commissioning, the production line has operated smoothly. Aggregate products exhibit cubic particle shape, with needle-like and flaky particles accounting for less than 5%. The manufactured sand gradation meets the Zone II medium sand standard, fully satisfying the needs of high-end commercial concrete plants. The replacement cycle of wear parts is among the industry's leading levels.
IV. Equipment and Process Recommendations
Based on your capacity requirements, we have selected the following core equipment combination to form a complete basalt crushing production line:
• Primary Crushing Unit: PE-900×1200 jaw crusher, maximum feed size 750mm, processing capacity 220-380 tons/hour, providing a stable material source for subsequent processes.
• Medium Crushing Core: HPT300 multi-cylinder hydraulic cone crusher, 100-200 tons/hour, equipped with fully automatic hydraulic clearing and overload protection, intelligent, efficient, and highly wear-resistant.
• Shaping and Sand Making: VSI6X1263 vertical shaft impact crusher (center feed with cascade feed), 150-280 tons/hour, combining crushing, shaping, sand making, and coarse grinding functions, with a high sand yield.
V. Frequently Asked Questions (FAQ)
Q1: How to choose between a cone crusher and an impact crusher for processing basalt?
A1: This is a crucial choice. Cone crushers offer superior wear resistance, energy consumption, and output stability, resulting in lower long-term operating costs, making them the primary choice for basalt crushing. Impact crushers produce better particle shape but cause significant wear on the hammer plates, making them suitable for applications with slightly lower raw material abrasiveness or where precise particle shape requirements are necessary. For scales of 100-150 tons/hour, cone crushers are generally recommended.
Q2: How to minimize energy consumption and wear costs in the production line?
A2: First, the process design should prioritize "more crushing and less grinding," with upstream crushing reducing the burden on downstream processes. Second, the core intermediate crushing equipment must be a hydraulic cone crusher designed for hard rock. Third, equip the production line with iron removers and pre-screening equipment to prevent iron parts and qualified fine materials from entering the intermediate and fine crushing equipment, causing unnecessary wear and energy consumption. Finally, select reliable equipment suppliers to ensure the quality of original equipment manufacturer (OEM) wear parts and the precision of equipment assembly.
Q3: How to ensure the quality of the final aggregate and manufactured sand?
A3: Product quality is determined by both the process and the equipment. Using a "cone crusher + vertical shaft impact crusher" process ensures excellent particle shape. Simultaneously, screening stages must be rationally set up in the production line to form a closed-loop cycle and strictly control the particle size of each stage of the product. A high-quality sand making machine combined with an air screen or classifier can effectively control the fineness modulus and stone powder content of the manufactured sand.
