      #Industry ·2025-02-25

      1. Design requirements and core challenges for high-performance mine crushers
      1.1 Industry Background and Demand Drivers
      Mining production pain points:

      The impact of large differences in ore hardness (e.g. iron ore, gold ore, granite, etc.) on crushing efficiency.

      High energy consumption and wear and tear lead to rising operating costs (crushing accounts for 30%~50% of the total energy consumption of the mine).

      Upgraded environmental protection requirements (dust emission, noise control).

      Design Objective:

      High performance: Improve the processing capacity per unit time (TPH) and crushing ratio (Crushing Ratio).

      Low Energy Consumption: Optimize the ratio of power consumption and output to meet the requirements of “double carbon”.

      Long service life: Extend the service life of wearing parts (jaws, hammerheads, liners).

      1.2 Core design challenges
      Dynamic load analysis and structural strength matching under complex working conditions;

      Balance of efficiency, energy consumption and cost in multi-objective optimization;

      Material selection and anti-fatigue design of high wear parts.

      2 Key technologies of high-efficiency crusher design
      2.1 Structural design and dynamic analysis
      Core structure optimization:

      Jaw crusher: optimize the trajectory of moving jaw (linear→curve) to improve crushing efficiency.

      Cone crusher: Comparison and improvement of laminar crushing chamber design (e.g. Symons type, HP type).

      Impact crusher: matching relationship between rotor speed and material throwing angle.

      Dynamics Simulation:

      Crushing process simulation based on ANSYS or EDEM, analyzing stress distribution and energy consumption.

      Fatigue life prediction and lightweight design of key components (spindle, bearing).

      2.2 Material science and surface treatment technology
      Application of high wear-resistant materials:

      Composite casting process of high manganese steel (Mn18Cr2) and cemented carbide (WC-Co).

      Ceramic coating (e.g. Al?O?-TiO?) plasma spraying technology on the liner surface.

      Impact toughness enhancement:

      Optimization of material microstructure by heat treatment process (quenching + tempering).

      2.3 Intelligent control and adaptive system
      Real-time monitoring based on IoT:

      Sensor network (vibration, temperature, current) to monitor equipment status and load changes.

      Intelligent adjustment technology:

      Dynamic adjustment of discharge opening gap through AI algorithm (e.g. hydraulic adjustment system for HP cone breaker).

      Adaptive variable frequency drive (VFD) optimizes the matching of motor power and speed.

      3. Multi-objective optimization method and innovative practice
      3.1 Optimization model construction
      Objective function:

      Maximize the processing capacity (TPH) and crushing ratio, minimize the energy consumption (kWh/t) and wear rate.

      Constraints:

      Equipment size limitation, material strength, motor power upper limit.

      3.2 Application of optimization algorithm
      Parameter Optimization:

      Genetic Algorithm (GA) optimizes the jaw swing frequency and stroke of the jaw crusher.

      Particle Swarm Algorithm (PSO) to solve the optimal solution of the cavity curve of the cone crusher.

      Topology Optimization:

      Lightweight design of frame structure based on Finite Element Analysis (FEA), reducing material cost by 15%~20%.

      3.3 Innovation Cases
      Case 1: A certain model of cone crusher improves crushing efficiency by 22% and reduces energy consumption by 18% through cavity optimization.

      Case 2: The application of composite wear-resistant liner in iron ore crushing extends the service life to 2.3 times of traditional materials.

      4 Application Challenges and Solutions
      4.1 Technical bottlenecks
      Insufficient wear prediction accuracy: it is difficult to accurately establish material wear models under complex working conditions.

      Countermeasure: Combine with digital twin technology to establish a “physical-data” dual-drive wear prediction system.

      Trade-off between energy consumption and efficiency: High crushing ratio may lead to exponential increase in power consumption.

      Countermeasure: Adopt multi-stage crushing process (coarse crushing + medium crushing + fine crushing) to reduce the load of a single machine.

      4.2 Economy and promotion obstacles
      High-performance materials and intelligent systems push up the initial cost.

      Countermeasure: Promote the shared equipment model of “pay per crushing volume” to lower the investment threshold of small and medium-sized mines.

      5. Future Development Direction
      Green design:

      Develop low-noise crusher (e.g. noise-reducing cavity structure, application of damping materials).

      Zero dust emission technology (closed crushing + negative pressure dust removal system).

      Intelligent upgrading:

      Machine vision-based online detection and closed-loop control of ore particle size.

      Digital twin-driven full life cycle performance management platform.

      New material breakthroughs:

      Self-repairing materials (e.g. microcapsule filling coating) in the exploration of the application of wear parts.

      6. Conclusion
      The design and optimization of high-performance mining crushers is the core link to improve the economic efficiency and sustainability of the mining industry. In the future, through the deep integration of material innovation, intelligent algorithms and green processes, crushing equipment will be
