A large-scale modular dolomite crushing and screening EPC production line with a capacity of 3,000 tons per hour, a daily output of 60,000 tons (20 hours), and an annual output of 10 million tons (330 days), specifically designed for large and medium-sized mines and large-scale aggregate processing applications. Suitable for supplying dolomite crushed stone and manufactured sand for rural road reconstruction, water conservancy projects, and urban infrastructure in countries such as Kazakhstan, Uzbekistan, and Kyrgyzstan.
Key Challenges: Remote and dispersed project sites are difficult to access; constructing fixed stations requires months of foundation pouring and makes relocation impossible; traditional hammer heads require replacement every 2–3 months, leading to frequent downtime and difficulties in parts replacement in remote areas; Manual operation requires daily round trips along bumpy mountain roads to the site; decentralized procurement leads to bureaucratic red tape and project delays exceeding budgets.
Solution Highlights: Modular, prefabricated units assembled on-site eliminate the need for large-scale foundation pouring, enabling production within 45 days; high-chromium alloy hammers with a hardness of 72 HRC offer 20 times the wear resistance of standard materials, requiring no replacement for 1.5 years; Customized anti-corrosion and anti-rust treatment on the machine body adapts to Central Asia’s harsh, cold, and dry climate, with core component replacement cycles exceeding industry standards by 3 times; the remote central control system can be set up in towns tens of kilometers away, allowing one person to manage 2–3 production lines; EPC turnkey contracting saves 30% on investment compared to decentralized procurement and reduces construction time by 35%; 24-month full-system warranty with a 99.5% fault repair rate.
Dolomite Crushing Equipment Process Flow
Raw material unloading → Uniform feeding via heavy-duty vibrating feeder → Primary crushing by jaw crusher → Secondary and tertiary crushing by impact crusher/cone crusher → Grading by circular vibrating screen → Oversize material returned to the circuit → Qualified products sent to the finished product pile. Remote start/stop, parameter adjustment, and fault diagnosis for the entire line; real-time monitoring of temperature, current, and vibration; automatic alarm for anomalies and precise fault localization. Can be equipped with a VSI sand-making machine for shaping to produce manufactured sand; the final product’s particle shape is controllable to meet the gradation requirements of highway and water conservancy projects.

Dolomite Crushing Equipment Project Case Studies
Dolomite Aggregate Project on Rural Roads in Zhambyl Region, Kazakhstan: Annual production of approximately 8 million tons of dolomite crushed stone and manufactured sand, supplying road reconstruction projects in three surrounding counties and townships. Stable operation at 3,000 t/h; high-chromium hammer heads have not been replaced for 18 months (compared to standard hammer heads, which typically require replacement every 3 months). The remote central control center is located in a town 80 km away, where a single operator manages two production lines simultaneously, reducing annual labor costs by approximately 60%. The equipment has operated without rust or malfunctions through winter temperatures of -25°C and summer temperatures of 45°C, with zero unplanned downtime during the 24-month warranty period. Customer Feedback: Commissioned in 45 days—20 days ahead of schedule—to supply aggregate for roadbeds, with a payback period 40% faster than traditional methods.
Dolomite Crushing Equipment FAQ
1. How long does it take to construct the foundation for a fixed station in remote mountainous areas? How soon can you achieve production?
The modular prefabricated structure eliminates the need for large-scale foundation pouring; the equipment is factory-prefabricated and assembled on-site. The EPC turnkey project takes 45 days from contract signing to production, saving 35% of the construction time compared to traditional methods high capacity quarry processing equipment. This is particularly suitable for projects with tight deadlines, such as rural roads in Central Asia.
2. How long do high-chromium alloy hammer heads last when processing dolomite?
High-chromium alloy hammer heads have a hardness of 72 HRC and are 20 times more wear-resistant than standard materials. Under the high-hardness conditions of dolomite, they can operate continuously for over a year and a half, significantly extending the replacement cycle compared to standard hammer heads (which typically last 2–3 months) continuous heavy duty operation crushing plant. This reduces the frequency of part replacements and the costs associated with engineers traveling to remote project sites.
3. Will the equipment rust or corrode in Central Asia’s harsh, dry climate?
No. The machine body undergoes custom anti-corrosion and anti-rust treatment, and the replacement cycle for core components exceeds industry standards by more than three times. Efficient Quarry Solution for Remote Locations It has withstood extreme temperature fluctuations ranging from -25°C to 45°C in Central Asian projects without rust or malfunctions, and is specifically designed for the harsh environments of remote dolomite crushing operations.
