Product Details
In high-end manufacturing sectors such as precision ceramics, electronic materials and catalytic materials, the precision, efficiency and stability of material grinding directly determine the performance and quality of downstream products.
With the rapid development of 5G communication, new energy, aerospace and other industries, the market has increasingly stringent grinding requirements for core materials including barium titanate dielectrics, zirconia ceramics and conductive silver paste. Traditional sand mills show growing shortcomings in high-flow production, ultrafine particle size control and equipment durability.
Longxin Intelligent Equipment Co., Ltd. has long been engaged in the grinding equipment industry. With profound insight into industry pain points and continuous technological innovation, the company focuses on technology and pursues high efficiency and stability, delivering innovative grinding solutions for high-end material manufacturers.
Rigid Growth Drivers of Nano Grinding Technology
Amid rapid iteration of new energy, new materials and intelligent manufacturing industries, nano-scale particle grinding has become a core factor governing product performance. Improvements in energy density of new energy battery materials, color uniformity of inks and coatings, and conductivity breakthroughs of photovoltaic electronic pastes all generate firm demand for high-flow, high-precision and low-energy-consumption nano grinding equipment.
Three core demands are reshaping industrial standards:
-
Capacity upgradingLarge-scale production of new energy batteries and photovoltaic modules pushes hourly processing capacity per unit from dozens of liters to hundreds of liters, making high-flow continuous production a basic requirement.
-
Precision breakthrough The D50 particle size of cathode materials such as lithium iron phosphate and ternary materials needs steady control within 100-300nm. Photovoltaic silver paste requires particle dispersion up to 99.9%. Traditional grinding equipment fails to meet such strict particle size distribution standards.
-
Intelligent adaptation Growing demand for flexible multi-variety and small-batch production requires rapid parameter switching and seamless connection with smart production lines, forming a closed-loop process of online monitoring, real-time adjustment and data traceability.
Against this backdrop, rod pin high-flow nano sand mills stand out with high-energy-density grinding and continuous production strengths. They serve as a vital link between laboratory formulas and industrial mass production, whose technological innovation directly underpins the competitiveness of downstream industries.
Working Principle & Equipment Structure: Innovative Design Breaks Traditional Grinding Bottlenecks
Adopting the core design concept of modular grinding assembly and new flow-through screen separation, Longxin intelligent rod-pin high-flow nano sand mill breaks the structural constraints of integrated grinding and separation in conventional sand mills, enabling independent optimization of efficient grinding and precise separation.
1. Core Working Principle
- Materials enter the grinding chamber via the feeding system. The combined turbine and rod-pin structure creates a 3D motion path with circumferential eddy current and radial impact. The turbine drives 0.2-0.5mm zirconia grinding beads to form high-speed circumferential circulation. Radial protrusions of rod pins generate high-frequency impact, refining material particles step by step under shearing, collision and extrusion effects.
- Large-area screen is applied for separation. It delivers higher flow capacity without compromising product quality, effectively solving screen clogging issues of traditional equipment.
2. Key Structural Components
-
Silicon Carbide Grinding Chamber Made of high wear-resistant and thermally conductive silicon carbide with hardness over HV1800. Its service life exceeds 5 times that of ordinary stainless steel. It rapidly dissipates grinding heat and restricts temperature rise inside the chamber.
-
Turbine Rod-pin Assembly Tungsten carbide rod pins with HRC90 hardness and special surface coating maintain uniform energy density at 1200-1800 r/min, preventing particle agglomeration caused by excessive local grinding.
-
Large-area Screen Reduces internal chamber pressure and heat buildup, significantly boosting production efficiency.
-
Intelligent Control System Equipped with PLC modules, temperature and pressure sensors. It collects real-time process data and automatically adjusts rotating speed and flow rate via algorithm models.

Performance Features & Technical Upgrades: From Basic Grinding to High-quality, Cost-effective and Stable Grinding
After a decade of technological iteration, Longxin Intelligent has achieved five core breakthroughs based on conventional rod-pin sand mills, with overall performance surpassing industrial standards.
-
Grinding Efficiency: 2-3 Times Higher Capacity Supported by modular grinding assembly and innovative flow-through screen separation structure, the effective grinding duration rises to 1.8 times that of traditional models. The flow area of the screen increases by 40%, boosting actual output to 2-3 times that of ordinary sand mills.
-
Particle Size Control: Precise D50 Deviation Management The composite turbine rod-pin structure delivers uniform shear force on particles. Adopting 0.2-0.5mm zirconia beads with roundness above 95%, the D50 particle size is steadily controlled within 100nm to 2μm, featuring narrower particle size distribution than industry average. It keeps low standard deviation in electronic ceramic ink production, ensuring smooth printing and consistent color tone.
-
Separation Technology: Mesh-free Design Solves Industrial Difficulties Centrifugal mesh-free separation eliminates two major drawbacks of traditional screen separation:
- Anti-clogging: Avoids blockage caused by high-viscosity materials and fibrous impurities. Continuous operation lifespan extends from 8 hours to 72 hours.
- Zero contamination: No contact between metal screen and materials cuts metallic impurity content, complying with purity standards for new energy materials and semiconductors.
- Energy Consumption & Cost: Improved Economic Efficiency Cost reduction realized via three energy-saving designs:
- Silicon carbide grinding chamber boasts thermal conductivity 3 times higher than stainless steel. Combined with wall cooling system, operational temperature stays stable without extra heat exchangers, cutting power consumption.
- Small-size grinding beads raise efficiency and reduce medium consumption under equal output.
- Wear-resistant components extend service life and lower maintenance costs.
- Intelligence & Compatibility: Standalone Operation to Production Line Collaboration
- Intelligent linkage: Compatible with MES system. Flow rate and rotating speed are adjustable via PLC. Real-time online particle size data feeds back to central control room to form closed-loop automatic parameter correction.
- Custom process packages: Pre-set formulas cater to cathode materials like layered oxide and Prussian blue, anode materials such as hard carbon and silicon-carbon, as well as photovoltaic silver paste and UV ink. Fast parameter switching shortens product changeover time.
- Multi-solvent adaptability: Suitable for water-based, oil-based and solvent materials. Grinding chamber can be replaced with polyurethane, silicon nitride or 316L stainless steel to meet sanitary standards for food and pharmaceutical industries.
Industry Adaptation: Customized Grinding Solutions for Diverse Fields
Longxin intelligent rod-pin high-flow nano sand mill has been widely applied in five major industries and serves as core production equipment for leading enterprises.
