10Mt/a Cobblestone Sand Making Line

As a turnkey high-efficiency sand making solution engineered exclusively for cobblestone processing, Zhongyu Dingli’s 10Mt/a (10 Million Tons Per Annum) Cobblestone Sand Making Line is tailored to address the core industry pain points of cobblestone sand making—high equipment wear (due to cobblestone’s Mohs hardness 7 and high silica content), poor finished particle shape, unstable large-capacity output, and high operational costs. Integrating advanced Crushing Equipment, Stone Crusher, Sand Maker, Vibrating Screen, and optional Mobile Crusher modules, this complete production line realizes a closed-loop process from cobblestone raw material feeding, multi-stage laminated crushing, precision screening, sand making & shaping, to washing and dehydration. Backed by Zhongyu Dingli’s 30+ years of expertise in Crushing Equipment manufacturing and proven by numerous successful large-scale cobblestone sand projects worldwide, it maintains stable 10Mt/a output, producing high-quality, cubic-shaped manufactured sand—ideal for large-scale cobblestone quarries, aggregate plants, commercial concrete mixing stations, and large infrastructure projects globally.

Core Advantages: 10Mt/a Stable Capacity & Cobblestone-Specific Optimization

1. Cobblestone-Specific Design, Conquering High-Wear & Hard Rock Challenges

Targeting cobblestone’s high hardness (Mohs 7) and high silica content (a major cause of equipment wear), the production line adopts a scientific three-stage crushing & sand making process: "Primary Crushing → Secondary Fine Crushing → Impact Sand Making & Shaping" [4]. The core Stone Crusher includes 2 sets of heavy-duty jaw crushers (primary crushing) and 3 sets of hydraulic cone crushers (secondary fine crushing), equipped with Zhongyu Dingli’s proprietary NM500 wear-resistant linings and reinforced rotors—extending wear part service life by 2.5 times compared to ordinary Crushing Equipment [1][6]. The Sand Maker (4 sets of vertical shaft impact crushers) adopts "stone-on-stone" and "stone-on-iron" dual-mode technology, optimizing finished sand particle shape, reducing needle-like and flaky content to ≤7%, and ensuring uniform gradation [4][7]. This exclusive configuration effectively solves the industry’s key pain points of rapid equipment wear and poor particle shape in cobblestone sand making.

2. 10Mt/a Stable Capacity, Guaranteed by Scientific Configuration & Proven Technology

Precisely optimized to achieve 10Mt/a annual capacity (equivalent to 1250-1300 TPH daily output based on 8000 working hours per year), the line maintains stable output with a fluctuation range of ≤4%, supporting 24/7 continuous high-intensity operation. It is equipped with 4 sets of large-capacity vibrating feeders (1500-2000 TPH per unit) to ensure uniform material supply to Stone Crusher, and 6 sets of 4-layer heavy-duty Vibrating Screen (500-600 TPH per unit) for multi-stage precision grading [4][7]. The closed-loop design (unqualified materials returned to Stone Crusher or Sand Maker for reprocessing) avoids material waste and ensures stable capacity output. The optimized power configuration (total power 1800-2000 kW) achieves energy-saving operation, with a comprehensive power consumption of only 2.0-2.5 kWh per ton of finished sand—lower than the industry average by 15% [3].

3. Full-Process Integration, Seamless Linkage of All Core Modules

The complete line forms a highly integrated Crushing Equipment system, with seamless linkage between Stone Crusher, Sand Maker, Vibrating Screen, and optional Mobile Crusher. The optimized process flow is tailored exclusively for cobblestone: Raw Cobblestone Feeding → Primary Crushing (Jaw Stone Crusher) → Secondary Fine Crushing (Cone Stone Crusher) → Precision Screening (Vibrating Screen) → Sand Making & Shaping (Sand Maker) → Fine Screening & Washing → Finished Sand Output [4][7]. The Vibrating Screen separates materials of different specifications (0-5mm, 5-10mm, 10-20mm), with qualified fine materials conveyed to Sand Maker for deep processing, and oversized materials returned toStone Crusher for re-crushing—improving overall line efficiency by 35%. For projects with complex terrain or temporary operation needs, optional Mobile Crusher (crawler/tire type) can be integrated to eliminate long-distance material transportation costs and realize on-site flexible crushing and screening [2][4].

4. Environmental Protection & Intelligent Control, Complying with Global Standards

Adhering to the global "green sand making" concept, the line is equipped with pulse dust collectors and fully enclosed Crushing Equipment, Sand Maker, and Vibrating Screen, achieving dust collection efficiency ≥99% and dust emission <20mg/m³—complying with global environmental protection standards [3][6]. The circulating water system (water reuse rate ≥90%) is configured for sand washing, reducing water consumption by 35% compared to traditional lines and avoiding environmental pollution caused by wastewater discharge [3]. Equipped with PLC + touch screen intelligent control system, it supports one-key start/stop, real-time monitoring of equipment load, production capacity, and wear status, and fault self-diagnosis—reducing manual operation intensity by 60% and ensuring safe, stable, and intelligent operation [3][4].

5. Durable Structure & Low Operational Costs, Maximizing Investment Returns

Built for long-term high-intensity cobblestone processing, all core equipment adopts a modular design with high-strength steel frames and sealed structures—effectively isolating dust, water, and impurities, and reducing equipment failure rate by 40% [1][3]. The Sand Maker and Stone Crusher use wear-resistant parts made of high-manganese steel and alloy steel, which are easy to replace and have low maintenance costs [1][6]. The optimized process design reduces material loss by 5%, and the energy-saving power configuration lowers long-term operational costs. With a service life of 15+ years for core equipment, the line ensures quick investment return for large-scale 10Mt/a projects.
