A 200–300-ton crushing line designed for the large-scale processing of medium- to high-hardness aggregates, producing high-quality aggregates in a variety of sizes for large-scale infrastructure projects and high-volume demand at quarries.
Core Introduction to the Production Line
The 200-300 tons/hour stone crushing production line is a fixed large-scale stone crushing and screening system, specially designed for ultra-high-capacity aggregate needs of mining, stone quarries, large-scale infrastructure projects, etc. It is mainly composed of LC3000×4000 hopper, ZSW1100×4200 vibrating feeder, C110 jaw crusher, CS250/PFW1320 secondary crusher, 4YK2470 vibrating screen and a full set of large-specification belt conveyors. The equipment has strong coordination and can achieve a stable ultra-high capacity of 300 tons per hour.
This production line can efficiently process various medium and high hardness raw stones such as limestone, granite, andesite, basalt, quartz and iron ore, and accurately produce a full range of construction aggregates including coarse aggregate, crushed gravel, stone chippings and fine aggregate. Each type of aggregate is suitable for core engineering scenarios: coarse aggregate is used for the production of ready-mixed concrete and asphalt concrete; crushed gravel is adapted to the paving of base and subbase courses in road engineering; fine aggregate is used for concrete pouring and wall plastering construction. The finished aggregates all comply with Chinese and international industry quality standards, meeting the large-volume and continuous aggregate supply needs of large mining sites, large-scale stone quarries, national-level infrastructure projects, etc.
1. Ultra-high capacity with mature process: Standard equipped with two-stage crushing process, the core adopts the combination of C110 jaw crusher for coarse crushing + CS250/PFW1320 for fine crushing, optimized for large-scale hard stone processing with high crushing efficiency and low equipment wear, achieving a stable ultra-high capacity of 200-300 tons/hour and adapting to commercial large-scale aggregate production.
2. Wide raw material adaptability and adjustable finished product specifications: Can efficiently process various stone materials such as limestone, granite, basalt, quartz, iron ore and river pebbles; conventional finished product particle sizes are 0-6mm, 6-12mm and 12-25mm, and specifications such as 0-5mm, 5-10mm, 10-20mm and 20-40mm can be customized according to customer needs to meet different engineering material standards.
3. High automation level and low labor cost: The entire production line realizes full-process automated closed-loop operation, only a small number of staff are needed to complete equipment start-stop, daily inspection and basic maintenance work without real-time on-duty personnel, greatly reducing the labor input of large-scale production.
4. Excellent finished product quality with strong market competitiveness: High production efficiency and low comprehensive operating cost, the finished aggregate has uniform particle size, cubic particle shape, reasonable gradation and low powder content, strong compressive resistance of aggregate, fully meeting the material requirements of high-end infrastructure and high-strength concrete production, with high market acceptance and strong liquidity.
5. Safe and stable operation with convenient control: Equipped with an advanced intelligent control system, it comprehensively ensures the safety and stability of high-load continuous production and effectively reduces the downtime for maintenance; the equipment operation interface is simple, with supporting detailed operation manuals, and the staff can take up their posts after simple training.
6. Full coverage of capacity specifications with free customized solutions: In addition to the core capacity of 200-300 tons/hour, crushing production lines with different capacities such as 50, 100, 150, 200, 300 and 400 tons/hour can be designed on demand. We provide customers with free customized process schemes, equipment configuration and detailed quotations.
Realize fully automated high-flow continuous operation with precisely controllable feeding volume, unqualified materials are recycled for re-crushing to achieve zero waste of raw materials, support environmental protection supporting transformation, and no manual intervention is required in the core processing links. The specific process is as follows:
1. High-flow feeding and quantitative steady flow conveying: Large hard stone blocks are fed into the raw material hopper by a loader, and uniformly and quantitatively sent to the jaw crusher by the ZSW1100×4200 vibrating feeder to precisely control the feeding flow and ensure the continuous operation of subsequent equipment under rated load.
2. Primary coarse crushing with high efficiency: Large raw stone blocks are subjected to primary coarse crushing by the C110 jaw crusher, and with the advantages of large feed inlet and high crushing ratio, the large raw stone blocks are efficiently processed into block materials suitable for fine crushing, laying a foundation for subsequent refined crushing.
3. Secondary fine crushing with optional configuration: The coarsely crushed materials are sent to the secondary crusher by the belt conveyor. CS250 cone crusher (special for hard stones) or PFW1320 impact crusher can be selected according to raw material hardness and finished product requirements, processing the materials to particle size close to finished products in a refined way and optimizing the aggregate particle shape and gradation at the same time.
4. Four-stage screening with closed-loop re-crushing: The finely crushed materials are conveyed to the 4YK2470 vibrating screen for four-stage high-precision classification and screening according to 0-5mm, 5-10mm, 10-20mm and 20-40mm specifications. Qualified finished products are sent to the designated area for stockpiling by the belt conveyor, which can be directly sold externally or used in on-site engineering; unqualified oversize materials are sent back to the secondary crusher for re-crushing to form a closed-loop production and ensure 100% qualified finished products.
5. Environmental protection supporting for green production: Environmental protection equipment such as pulse jet bag filter, noise reduction device and spray system can be equipped as needed during the operation of the production line, effectively controlling dust and noise pollution. The dust emission complies with global environmental protection standards, adapting to operation in multiple regions such as cities, suburbs and mining areas.
