The crushing ratio can reach more than 1:30, which is significantly higher than traditional crushers (usually 1:10-1:15). It can reduce the number of crushing stages without the need for additional secondary or tertiary crushing equipment, greatly shortening the process flow;
• Direct Processing of Large Raw Materials: Can directly crush large raw materials with a particle size of 800-1200mm, eliminating the need for pre-crushing or pretreatment by manual labor. It is especially suitable for large hard rocks, pebbles and other raw materials commonly found in mining in Nigeria, saving pretreatment time and labor costs;
• Significant Improvement in Single-Machine Efficiency: The increase in crushing ratio drives a significant improvement in single-machine processing efficiency. It can process more raw materials in the same time, with an hourly output 20%-40% higher than that of traditional equipment, easily meeting the efficient supply needs of large-scale production.

During the crushing process, it is not easy to block, and the energy consumption is stable, adapting to multiple raw material processing scenarios such as mining, aggregate production, and solid waste recycling;
• Flexible Adjustment of Finished Product Specifications: Equipped with an intelligent screening system, it can accurately produce various specifications of finished products according to needs, such as 0-5mm manufactured sand, 5-10mm fine aggregate, 10-20mm medium aggregate, and 20-31.5mm coarse aggregate, meeting the material needs of different projects such as expressway surface courses, concrete mixing, road cushions, and building masonry;
• Flexible Scenario Switching: Fixed high crushing ratio crushers are suitable for large-scale operation scenarios such as large mines and aggregate bases; mobile high crushing ratio crushers (tire-type/crawler-type) have the advantages of convenient transition and small floor space, adapting to scattered operation scenarios such as rural road construction, suburban engineering, and small quarries, realizing rapid adaptation to different scenarios.

III. Cost Reduction and Efficiency Improvement: Optimization of Whole-Life Cycle Operating Costs

From equipment design and material selection to process optimization, Dongmeng's high crushing ratio crusher comprehensively reduces operating costs, helping Nigerian customers achieve the production goal of "low cost and high output."

• Reduction of Equipment Investment Costs: The ultra-high crushing ratio can reduce the number of crushing stages, eliminating the need for additional secondary and tertiary crushing equipment, and reducing the equipment investment cost of a single production line by about 30%; the modular design supports on-demand combination, avoiding the purchase of redundant equipment and further saving initial investment;
• Reduction of Energy Consumption and Loss: The optimized crushing principle makes material crushing more sufficient, and the energy consumption per finished product is 15%-25% lower than that of traditional equipment; core vulnerable parts are made of high-wear-resistant alloy materials, and the optimization of the crushing cavity reduces component wear. The service life of vulnerable parts is increased by 30%-50%, reducing the cost of spare parts replacement and downtime;
• Improvement of Resource Utilization Rate: It has excellent crushing effect on low-grade ore, mine tailings, construction solid waste and other raw materials, which can fully tap the value of recycled resources and realize "turning waste into treasure." It not only reduces the cost of raw material procurement but also meets the requirements of environmental protection policies, improving the comprehensive benefits of the project.
