In the mining industry, the efficiency of the production line and the quality of the finished product directly determine a company's core competitiveness. When you need to process 250-300 tons/hour of rock material with a feed diameter of 350 mm and a final output of 30 mm aggregate, a scientifically designed and rationally configured crushing production line is not only a guarantee of production but also the key to profitability.
I. Core Requirements and Technical Challenges of the Production Line
Faced with raw rock material that is hard and has a large particle size, the production line must overcome several key challenges: First, the primary crushing equipment must have strong crushing capacity and tolerance to handle 350 mm large pieces of material; second, the secondary and fine crushing stages need to precisely control the output particle size to ensure the proportion and excellent particle shape of the 30 mm finished product; finally, the entire system must maintain continuous and stable operation to achieve a stable output of 250-300 tons/hour. This requires the coordinated operation of equipment in each stage, like a precise industrial symphony.
II. Classic Equipment Configuration Scheme
Based on hundreds of successful cases, we recommend the following core configuration scheme. This scheme uses a three-stage crushing process—jaw crusher for coarse crushing, cone crusher for medium crushing, and impact crusher for shaping—as its main component, while also considering efficiency, finished product quality, and equipment durability.
Typical Configuration Table for 250-300t/h Rock Crushing Production Line
| Equipment Name | Recommended Model | Key Parameters | Main Functions |
| Vibrating Feeder | GZD-1500×6000 | Feed size ≤400mm, processing capacity 400t/h | Uniform feeding, pre-screening of impurities |
| Jaw Crusher (Coarse Crushing) | PE-900×1200 | Feed opening size 900×1200mm, maximum feed 350mm | Primary crushing, crushing 350mm rock to ≤200mm |
| Cone Crusher (Medium Crushing) | HPC-400 | Maximum feed ≤200mm, discharge opening adjustment range 25-50mm | Medium and fine crushing, producing ≤60mm intermediate products |
| Impact Crusher (Shaping) | VSI-1140 | Maximum feed ≤60mm, adjustable finished product particle size | Sand making and shaping, optimizing finished product particle shape |
| Circular Vibrating Screen (Multi-layer) | 3YK-3070 | 3-layer screen, screen size adjustable | Grades and screens to produce finished products of 0-5mm, 5-20mm, 20-30mm, etc. |
Note: Actual configuration needs to be fine-tuned according to the hardness and abrasiveness of the rock material (such as granite, basalt, limestone, etc.), and equipped with corresponding belt conveyors, electrical control systems, and dust removal and noise reduction devices.
III. Advantages and Investment Value of the Solution
The essence of this production line design lies in "high-efficiency coarse crushing, precise medium crushing, and high-quality shaping." The jaw crusher, as the core of coarse crushing, ensures efficient processing of 350mm large materials with its robust structure and deep cavity design; the cone crusher adopts the principle of layered crushing, effectively reducing equipment wear while achieving medium crushing; the final impact crusher significantly improves the cubic particle shape of the finished aggregate, enhancing the product's market value. The entire line adopts a central intelligent control system, enabling one-button start/stop, fault warning, and remote monitoring, significantly reducing labor costs and maintenance difficulty.
From an investment return perspective, based on a production capacity of 280 tons per hour, 10 hours of operation per day, and 300 production days per year, the annual output of high-quality aggregate can reach 840,000 tons. At current market average prices, the entire production line investment cost can be recovered within 2-3 years. The 20-30mm high-quality aggregate produced is a sought-after material for commercial concrete and roadbed construction, possessing significant market competitiveness.
