The 180–220-ton crushing line is specifically designed to process medium- to high-hardness rock, producing high-quality aggregates in a variety of sizes to meet the large-scale material requirements of major infrastructure projects.
The 180-220 tons/hour stone crushing production line is a fixed high-capacity hard stone crushing and screening system, supporting flexible customization of two-stage/three-stage crushing processes. It is mainly composed of LC3000×4000 hopper, ZSW1100×4200 vibrating feeder, PE750×1060 jaw crusher, CS220/HPC300 cone crusher (replaceable with PF1320 impact crusher), 4YK2470 vibrating screen and a full set of large-specification belt conveyors. The equipment is adapted to high-flow continuous production and can achieve a stable capacity of 200 tons per hour.
This production line is specially designed for processing medium and high hardness raw stones such as limestone, granite and andesite, and can efficiently produce a full range of construction aggregates including coarse aggregate, crushed stone mixture, 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 stone mixture 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 demand of large stone quarries, large-scale infrastructure projects and mine supporting aggregate processing.
1. High capacity with flexible process, adapted to hard stone processing: Standard equipped with two-stage crushing process, customizable three-stage process. The core adopts the combination of jaw crusher for coarse crushing + cone crusher for fine crushing, optimized for high-hardness stone materials with high crushing efficiency and low equipment wear, achieving a stable high capacity of 180-220 tons/hour and adapting to large-scale commercial production.
2. Wide raw material adaptability and adjustable finished product specifications: Can efficiently process various stone materials such as limestone, granite, andesite, dolomite, quartz 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 needs to meet diverse 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 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, low powder content and strong compressive resistance, fully meeting the material requirements of high-end infrastructure projects with high market acceptance and strong liquidity.
5. Safe and stable operation with convenient and reliable 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 180-220 tons/hour, crushing production lines with different capacities such as 50, 100, 150 and 300 tons/hour can be designed on demand. We provide customers with free customized process schemes, equipment configuration and detailed quotations.
Working Process of the Production Line
The production line realizes 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, and it supports environmental protection supporting transformation with no manual intervention required in the core links. The specific process is as follows:
1. High-flow feeding and quantitative 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, avoid overload of subsequent equipment from the source and ensure high-capacity continuous production.
2. Primary coarse crushing with high efficiency: Large raw stone blocks are subjected to primary coarse crushing by the PE750×1060 jaw crusher, the large feed inlet is adapted to stone blocks larger than 500mm, and the raw stones are processed into 100-200mm block materials with high crushing ratio, laying a foundation for subsequent fine crushing.
3. Secondary fine crushing with optional configuration: The coarsely crushed materials are sent to the fine crushing equipment by the belt conveyor. CS220/HPC300 cone crusher (special for hard stones) or PF1320 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 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 or used on site; unqualified oversize materials are sent back to the fine crushing equipment 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 and noise reduction device 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 and suburbs.
