As the mainstream production capacity range for sand and gravel aggregate production, 100-800 tons/hour stone aggregate production lines are designed to adapt to the needs of projects of varying scales, match diverse raw material characteristics, and meet differentiated end-product applications. They can support localized material supply for small and medium-sized projects while also providing a stable supply of aggregate for large-scale infrastructure projects. Core applications can be categorized into four main categories based on capacity gradient and application scenarios.
1. 100-200 tons/hour: Small and Medium-sized Projects and Regional Energy Supplementation
Core Positioning
Serving the needs of small and scattered local construction projects, filling gaps in the coverage of large production lines, and flexibly adapting to small-scale raw material reserves and limited site conditions.
Main Applications
Rural Infrastructure and Municipal Maintenance
Used for rural road hardening (such as roadbed fill and pavement base aggregate for village roads), township sewage treatment plant construction (sedimentation tank lining and pipeline backfill), and urban municipal maintenance (gravel for sidewalk renovation and sewer reconstruction). In such scenarios, aggregate demand is small (typically 10,000-30,000 tons) and lead times are short (1-2 months). A production capacity of 100-200 tons/hour allows for rapid response, avoiding the problems of overcapacity and high transportation costs associated with large production lines.
For example, a rural road reconstruction project in a certain county required 25,000 tons of aggregate in two grades, 5-10mm and 10-20mm. Using a 150-ton/hour production line, the supply could be completed in 20 days. Local weathered rock can be utilized, reducing transportation costs.
Small Building Materials Processing and Support
Supplying raw materials (such as crushed shale for bricks and fine aggregate for precast panels) to small brick and cement precast factories. Our production capacity precisely matches the raw material consumption rate of downstream companies (small brick factories typically require 300-500 tons of aggregate per day), preventing raw material backlogs or supply shortages. The production line can also flexibly adjust the finished product particle size based on downstream demand (e.g., brick factories require ≤5mm fine aggregate, precast parts factories require 5-15mm aggregate), providing strong adaptability.
II. 200-400 tons/hour: Regional Projects and Commercial Aggregate Supply
Core Positioning
This line covers the needs of medium-sized construction projects within prefecture-level cities, balancing production capacity and market reach, and balancing direct supply to projects with commercial aggregate sales.
Main Applications
Medium-sized Transportation and Housing Construction Projects
This line serves prefecture-level cities for the construction of expressway connectors, new secondary highways (e.g., a ring road project in a prefecture-level city requires 150,000-200,000 tons of aggregate), and medium-sized residential complexes (e.g., concrete aggregate for 10-15 high-rise residential buildings, approximately 80,000-120,000 tons). The 200-400 ton/hour production capacity enables a daily feed of 2,000-3,000 tons, meeting the project's continuous construction needs. The production line is typically located within 30-50 kilometers of the project site, keeping transportation costs at 15-25 yuan/ton, making it more cost-effective than purchasing aggregate from large-scale production lines.
Regional Ready-Mixed Concrete Mixing Plant Support
This system provides a stable supply of raw materials for 3-5 small and medium-sized ready-mixed concrete mixing plants within a prefecture-level city (each with an average daily aggregate demand of 800-1,200 tons). Through a "long-term agreement + on-demand supply" model, it addresses the pain points of mixing plants: the high cost of building their own production lines and the inconsistent quality of purchased aggregates. The production line can stably produce three grades of aggregate: 5-10mm, 10-20mm, and 20-30mm, tailored to the plant's needs. Intelligent control ensures particle shape (needle-shaped or flake-like particles ≤ 8%) and gradation stability, meeting C30-C50 concrete production standards.
III. 400-600 tons/hour: Large-scale Infrastructure Distribution and Industrial Cluster Support
Core Positioning
Serving as a "regional distribution station" for large-scale infrastructure projects or a "raw material guarantee center" for industrial parks, it bridges large-scale demand with localized production.
Main Applications
Large-Scale Infrastructure Project Distribution
Provides "local distribution" services for high-speed rail and highway mainline sections (e.g., a high-speed rail section requiring 500,000-800,000 tons of aggregate) and medium-sized water conservancy projects (e.g., small reservoir reinforcement and river management projects requiring 300,000-500,000 tons of aggregate). Because large-scale infrastructure projects typically span tens of kilometers, a single large production line is difficult to cover the entire length. Therefore, a 400-600 tons/hour production line can serve as a "distribution station," located midway along the project or in areas with concentrated raw materials. It can supply 4,000-5,000 tons of aggregate per day. Combined with belt conveyors or short-distance truck transport, this achieves "multi-point supply, reduced long-distance transportation," and reduces the overall aggregate cost of the project. Building Materials Industrial Park Support
This facility provides an integrated raw material supply system for building materials industrial parks (such as those integrating cement plants, aggregate processing plants, and precast component plants). With a production capacity of 400-600 tons/hour, it can meet the raw material needs of multiple companies within the park (e.g., a park with an average daily aggregate consumption of 3,000-4,000 tons). Furthermore, the production line utilizes a cascaded utilization model: coarse aggregate is supplied to the cement plant as a blending material, while medium and fine aggregate is supplied to the aggregate processing plant and precast component plant, achieving full raw material utilization and improving the overall efficiency of the industrial park.
IV. 600-800 tons/hour: Main material supply for large-scale projects and regional market dominance
Core Positioning
Supporting the main aggregate demand for ultra-large projects, the company may become a core aggregate supplier within the region (such as provincial capitals and economic zones), offering high production capacity, high quality, and high stability. Main Applications
Main Aggregate Supply for Ultra-Large Infrastructure Projects
Serving as the primary aggregate supply line for high-speed rail trunk lines, ultra-large expressways (such as cross-river bridges and tunnel clusters, which require 1-2 million tons of aggregate), and large water conservancy projects (such as new medium-sized reservoirs and river embankment reinforcement, which require 800,000-1.5 million tons of aggregate), the production line boasts a production capacity of 600-800 tons/hour, enabling a daily aggregate supply of 6,000-7,000 tons. Combined with a storage silo (capacity ≥ 50,000 tons), it can handle emergencies such as the rainy season and equipment maintenance, ensuring continuous construction. Furthermore, the production line must meet high-grade aggregate standards (e.g., compressive strength ≥ 80 MPa and flake content ≤ 5% for high-speed rail ballastless track). A multi-stage crushing and shaping process ensures consistent finished product quality. Core Suppliers in the Regional Market
In provincial capitals or economic zones (such as those surrounding the Yangtze River Delta and Pearl River Delta), production lines with a capacity of 600-800 tons/hour can dominate the regional aggregate market through their scale advantage. Through a "bulk supply + long-term partnership" model, they can provide raw materials to 20-30 large-scale ready-mix concrete batching plants and precast component factories, supplying an average of 5,000-6,000 tons of aggregate daily and capturing 30-40% of the regional aggregate market share. Furthermore, these production lines can extend the supply chain (e.g., by supporting manufactured sand production and dry-mix mortar processing), increasing product value and becoming a core node in the regional building materials supply chain.
V. Common Value: Adapting to Policies and Market Trends to Achieve Sustainable Development
Regardless of production capacity, 100-800 t/h stone production lines must comply with "Green Mining" and "Smart Production" policy requirements and market trends. Their common value lies in:
Environmental Compliance: Through fully enclosed plant, pulse dust removal (dust emissions ≤ 10 mg/m³), and wastewater recycling (utilization rate ≥ 95%), they meet national and local environmental standards and avoid production stoppages due to environmental issues.
Intelligent and Efficient: Equipped with a PLC control system, they enable equipment linkage and fault warnings, reducing manual intervention (reducing labor by 30% compared to traditional production lines) and improving overall equipment utilization (consistently above 90%).
Raw Material Adaptability: The crushing process can be adjusted based on local raw material characteristics (e.g., soft rock, medium-hard rock, or hard rock), maximizing the use of local resources and reducing the risk of relying on external raw materials, achieving "local materials, local production." In summary, the core purpose of the 100-800 t/h aggregate production line is to provide aggregate solutions with controllable costs, stable quality, and timely supply for construction projects of varying scales and types through "capacity grading to meet demand, process customization to suit raw materials, and service extension to suit the market." This serves as a key link in supporting the development of the infrastructure and building materials industries.
