Expanding Overseas • Steady Implementation | Chongqing Sanming Heavy Industry's 5 Million Ton Annual Gravel Production Line in Kyrgyzstan Successfully Star
Rooted in craftsmanship and dedicated to product developmentwe focus on pragmatism to empower overseas markets. Recently, a 5 million ton/year e processing production line in Bishkek, Kyrgyzstan, supplied with complete crushing equipment and technical support by Chongqing Sanming Heavy Industry, has successfully completed full-line comming and trial operation with material, entering smooth production. [Video Caption] Adapting to local conditions, customizing exclusive processes The local area boasts abundant river pebble resert the stones are highly hard and contain a large amount of mud, imposing extremely high requirements for equipment compatibility. Combining local climate, site conditions, and production capacity needs, Sanming Hey customized a complete process solution after on-site surveying: jaw crusher for coarse crushing mud removal screen for impurity removal VF impact crusher for medium and fine crushing and shapinar vibrating screen for grading. The production line features a streamlined structure and stable operation, precisely matching the needs of large-scale aggregate production.
Rigorous control across the entire chain forges high-quality aggregates.The entire production chain features clear division of labor and strong adaptability, utiliz combination of Jaw Crusher VF Impact Crusher to establish a benchmark for short-process, high-efficiency production: - Coarse crushing with deep-chamber jaw crusher: Processes laoulders with a high reduction ratio, no clogging, and stable operation, completing preliminary size reduction. - Mud removal screening: Effectively separates ore from mud and clay impurities, significaning material mud content. It provides clean raw materials for subsequent crushing, screening, and sand-making processes, reducing blockages, jamming, and excessive wear on equipment. - Dual-purpose VF Impact Crusher: Relying on impact crushing principles, it effectively breaks up materials and modifies aggregate shape based on the high hardness and rounded nature of boulders. Ite proportion of flaky and elongated particles, ensuring the regularity of crushed stone products to meet infrastructure material standards. - Efficient separation with circular vibrating screen: Effectively screens different speci of finished aggregates (such as 1-2 stone, 1-3 stone, 0-3mm sand, etc.), strictly controlling the particle size distribution of the finishect to ensure that the particle size of each specification meets engineering standards.
Short-process technology achieves cost reduction and efficiency improvementThis project adopts a streamlined short-process technology, utilizing the "Jaw Crusher Impact Crusher" goldenmbination to balance capacity, quality, and cost-effectiveness: 1. Streamlined process: Reduces crushing stages and conveying equipment, shortens transport distances, and saves plant flor space. 2. Low consumption and energy saving: Simplified equipment configuration reduces O&M, energy consumption, and labor costs, shortening the investment payback period. 3. Stable performance: ble for high-hardness river pebble scenarios, with strong continuity; finished aggregates feature uniform particle shape and standard gradation.
