1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Are escalating operational costs and unpredictable downtime eroding your limestone quarry’s profitability? You face a demanding landscape: abrasive material wearing down components, volatile energy prices impacting margins, and the constant pressure to increase yield without compromising safety. Hãy xem xét những thách thức chung này:
Độ mòn cao & Chi phí bảo trì: Abrasive limestone dust and material rapidly degrade crusher liners, băng tải, and loader buckets, leading to frequent part replacements and unplanned maintenance stops.
Năng lượng kém hiệu quả: Lớn hơn, nonoptimized crushing and grinding circuits consume excessive power per ton of processed material, making your operation vulnerable to energy price fluctuations.
Kích thước sản phẩm không nhất quán: Poorly calibrated or worn equipment produces offspec aggregate, dẫn đến việc từ chối sản phẩm, chu trình nghiền lại, and lost revenue from premium product tiers.
Lỗi kiểm soát phát thải bụi: Ineffective dust suppression creates environmental compliance risks, health hazards for personnel, and community relations issues.

What if your primary crushing and downstream processing could be more predictable, costcontained, và hiệu quả? Giải pháp không nằm ở một cỗ máy duy nhất, but in a matched system designed for the specific rigors of China limestone mining.

2. TỔNG QUAN SẢN PHẨM

This content outlines the critical considerations for a HeavyDuty Crawler Mobile Crushing & Nhà máy sàng lọc, engineered explicitly for the physical and economic demands of commercialscale limestone quarrying in China. This integrated system is designed for direct feed from excavators or wheel loaders at the rock face.

Quy trình hoạt động:
1. Cho ăn chính & Sàng lọc trước: mỏ đá Runof (ROQ) limestone is fed via excavator onto a robust vibrating grizzly feeder, which removes fine abrasives and subfines before primary crushing.
2. Nghiền sơ cấp: A highinertia jaw crusher reduces large limestone blocks (lên đến kích thước nguồn cấp dữ liệu được chỉ định) to a manageable diameter.
3. Truyền tải tích hợp & Dự trữ: Crushed material is transferred via heavyduty conveyors—equipped with dust skirts—to either a direct stockpile for base material or an optional closedcircuit secondary screening unit.
4. ClosedCircuit Screening (Không bắt buộc): A return conveyor allows oversize material to be recirculated back into the crusher, ensuring precise final product sizing without manual intervention.

Phạm vi ứng dụng & Hạn chế:
Phạm vi: Ideal for medium to largescale limestone quarries requiring onsite primary crushing to reduce haulage costs or create saleable aggregate at the source. Suitable for multipit operations due to its mobility.
Hạn chế: Not designed for extremely hard or abrasive igneous rock (ví dụ., đá granit) không có cấu hình lót cụ thể. Site mobility requires relatively even terrain; steep grades may necessitate preparation.

6. KỊCH BẢN ỨNG DỤNG

Large Regional Quarry Operator， Shandong Province｜Challenge： Needed to service three separate pits within a single mining lease but hauling raw stone to a central fixed plant was costing over ¥1。2/ton/km in trucking expenses。｜Giải pháp： Deployment of one HDCMCS1200L unit， sequentially moved between pits every 68 tuần。｜Kết quả： Eliminated over ¥180，000 monthly in trucking fuel and maintenance costs。 The plant’s quick setup allowed each pit transition within one nonproductive shift。

Aggregate Producer Supplying Cement Plant｜Challenge： Existing stationary primary crusher produced excessive fines (<3mm)， which was waste for their coarse aggregate contracts， yet valuable as cement raw material。 They lacked efficient separation。｜Giải pháp： Implementation of our mobile solution with an added secondary screen deck。 The circuit was tuned to scalp out fines precrush while separating two coarse product fractions postcrush。｜Kết quả： Created two new revenue streams from previously wasted fines （sold directly to the cement plant）and improved yield of premium coarse aggregate by approximately18%。 Payback period was calculated at under14 months。
