Aggregate production line is a key production system used for producing aggregates used in construction and infrastructure. It processes large ores or rocks into aggregates that meet construction standards through crushing, screening, cleaning and other processes, which are widely used in concrete, highway, railroad, bridge and other engineering construction.
1. Continuous operation: Crushing, conveying,and screening equipment operate in tandem to achieve assembly line production, significantly reducing manual intervention and downtime.
2. High processing capacity: Designed for different rock hardnesses (such as granite, limestone, etc.), the hourly output can range from tens of tons to thousands of tons, meeting the needs of large-scale engineering projects.
3. Intelligent control: Modern production lines are typically equipped with PLC control systems, which monitor equipment status in real time, adjust parameters, and optimize production rhythms.
1. Multi-stage crushing and screening: Through a combination of jaw crushers (primary crushing), cone/impact crushers (secondary and tertiary crushing), and sand-making machines (shaping), the material is subjected to graded crushing to reduce over-crushing.
2. Precise grading: Vibrating screens are configured with multiple layers of screens (e.g., 3-4 layers) as needed, producing aggregates of various specifications such as 0-5mm, 5-10mm, and 10-20mm, to meet the requirements of different applications such as concrete and asphalt.
1. Dust control: Closed conveying, spray systems, pulse dust collectors, etc. are used to ensure dust emissions ≤ 20 mg/m³, meeting environmental protection standards.
2. Noise control: Equipment vibration-reducing foundations and soundproof enclosures are designed to reduce noise to below 75 dB.
3. Resource recycling: Can be combined with construction waste treatment modules to produce recycled aggregates.
1. Modular design: The equipment combination can be flexibly adjusted according to raw material characteristics (hardness, mud content) and production capacity requirements (e.g., “jaw crusher + cone crusher” is suitable for high-hardness rocks, while “jaw crusher + impact crusher” is suitable for medium-to-low hardness rocks).
2. Expandability: Modules for sand recovery and sand washing can be added later to enhance product value.
1. Long service life design: Key components are made of high-manganese steel or composite wear-resistant materials, extending service life by 2-3 times.
2. Easy maintenance: Hydraulic lid opening and automatic lubrication system simplify maintenance procedures and reduce downtime.
3. Compact layout: Compact design saves space, and belt conveyors reduce transfer costs.
