Project Location: Heihe City, Heilongjiang Province
Commissioning Year: 2024
Design Capacity: 500 tons/hour
Core Equipment: C125 Jaw Crusher; CH440 Single-Cylinder Cone Crusher (250kW motor) for medium-coarse crushing; two CH430 Single-Cylinder Cone Crushers (Meishuo Intelligent Equipment) for fine crushing; three vibrating screens.
A Model of High-Efficiency Crushing in Extreme Cold
Located in a region characterized by extreme cold and long winters, Heihe, Heilongjiang, poses rigorous challenges for aggregate production equipment regarding cold resistance, impact resilience, operational reliability, and automated control. To handle local hard rock and meet high-volume demands, this production line utilizes a three-stage closed-circuit crushing system—featuring a C125 primary crusher, one CH440 (medium-coarse), two CH430s (fine), and three vibrating screens—achieving a stable hourly output of 500 tons under harsh environmental conditions.
Key Configuration Highlights
High-Performance Primary Crushing: A large C125 jaw crusher is installed at the front end; featuring a large feed opening and robust load-bearing capacity, it effectively processes large raw ore blocks and ensures a balanced feed for subsequent stages.
Graded Fine Crushing: The core medium-to-fine crushing stage employs a cluster of single-cylinder hydraulic cone crushers from Meishuo Intelligent Equipment. A high-power (250kW) CH440 handles the second stage (medium-coarse crushing) to rapidly reduce particle size, followed by two CH430 units for the third stage (closed-circuit fine crushing and shaping); the inter-particle (lamination) crushing principle significantly improves aggregate shape quality by minimizing elongated and flaky particles.
High-Precision Screening Loop: Three heavy-duty vibrating screens are arranged in a cascading configuration to ensure precise grading and rapid material recirculation, resulting in finished aggregates with optimal particle size distribution. Delivering Core Value to Customers
Stable operation in extreme cold, drastically reducing unplanned downtime: Equipped with fully automated hydraulic and lubrication heating/monitoring systems, the Meishuo intelligent cone crusher features remote one-touch discharge setting adjustment and automatic tramp-iron release and reset. It maintains continuous, high-efficiency operation even in low-temperature conditions, significantly boosting equipment uptime.
Superior particle shape and gradation, commanding a premium in the end market: By utilizing inter-particle (lamination) crushing, the CH440 and CH430 models effectively overcome the drawbacks of traditional impact crushers (prone to high wear) and standard cone crushers (producing excessive flaky or elongated particles). The resulting aggregates feature a rounded shape and controllable fines content, meeting local standards for high-grade concrete and infrastructure projects, thereby enabling customers to command a price premium based on superior product quality.
Significant reduction in energy consumption per ton and maintenance costs: The combination of a high-power 250kW motor and an optimized crushing chamber achieves high throughput and a high reduction ratio with low energy consumption per unit of output. High wear-part utilization and extended replacement intervals for consumables effectively lower the customer's long-term expenditure on spare parts and labor for maintenance.
