Description
Product Introduction
The use of manufactured sand is becoming increasingly widespread; however, the particle shape and gradation of manufactured sand produced by different processes and equipment can vary significantly, markedly affecting concrete workability and strength. Traditional mechanical sieving methods are not only time‑consuming and labor‑intensive with low efficiency but also fail to accurately quantify morphological parameters—such as the content of flaky and elongated particles and roundness—that decisively influence concrete workability and strength. The proposed device employs a modular architecture and high‑speed dynamic imaging to simultaneously analyze particle size distribution and morphological characteristics for solid particles in the 10–100 μm range, enabling multidimensional particle characterization that encompasses both size and shape.
Product Features:
1. Simultaneous analysis of particle size and morphology parameters to establish a multidimensional particle characterization system.
The system not only provides particle size distribution data but also outputs key morphological parameters such as sphericity and aspect ratio, enabling quantitative assessment of particle structural characteristics. Leveraging image‑recognition algorithms and boundary‑extraction techniques, the software precisely analyzes particle contours, minimizing errors caused by particle overlap or edge blurring and thereby providing a more comprehensive analytical foundation for optimizing material performance.
2. Dual-mode testing architecture, balancing the needs of laboratory and online applications.
It supports two operating modes: offline rapid testing and online continuous monitoring. The offline mode is ideal for laboratory sample evaluation, enabling rapid statistical analysis of samples; the online mode can be integrated into production processes to provide real-time monitoring of particle characteristics and trend recording, thereby supporting process control and batch‑to‑batch consistency management.
3. Enables analysis of massive particle data with strong data representativeness.
By leveraging dynamic delivery and high-speed acquisition, the LBT-300D Intelligent Particle Morphology Analyzer for Manufactured Sand enables continuous statistical analysis of large‑scale particle samples. Compared with static sample preparation, this system substantially increases both the data volume and statistical robustness, yielding particle size distribution and morphological parameter results that are more representative and reliable.
4. Specially designed optical assembly for enhanced clarity.
The instrument employs a large‑depth‑of‑field, telecentric optical design, coupled with a constrained planar sampling window architecture, to enhance particle image clarity and edge‑detection accuracy. Optimized optical components effectively minimize image distortion and background interference, ensuring the accuracy and consistency of morphological analysis results.
5. Pull-out design for easier and faster maintenance and upgrades.
The pull‑out sampling window and collection tray are designed for easy lens maintenance and cleaning, reducing long‑term operating costs. For high‑value or scarce samples, the system enables sample recovery and reuse, balancing experimental efficiency with resource management requirements.
Software Features:
1. High-Throughput Image Processing and Intelligent Recognition Algorithms
The LBT-300D software platform employs high-speed image acquisition and automated recognition algorithms to perform real-time segmentation and contour extraction of particles continuously passing through the measurement zone. By leveraging an optimized edge‑detection and noise‑filtering mechanism, the system minimizes the impact of particle overlap, adhesion, or background interference on the results, thereby enhancing the stability and consistency of morphological parameter calculations. Under dynamic testing conditions, the software can continuously process large volumes of particle image data, ensuring that particle size distribution and morphological statistics are based on a robust sample set and exhibit strong statistical representativeness.
2. Multi-parameter statistical analysis and distribution model support
The software supports simultaneous statistical analysis of multidimensional morphological parameters, including particle size distribution, sphericity, and aspect ratio, and offers multiple distribution representations—such as volume‑based, number‑based, and cumulative distributions. Users can overlay and compare data from different batches or time periods, enabling trend analysis to facilitate process optimization and quality control. The system also provides adjustable statistical thresholds and customizable filtering criteria, meeting the demands for granular data analysis in both research and engineering applications.
3. Data Management and Method Standardization Platform
The LBT-300D software supports saving and recalling test methods, enabling standardized management of testing workflows for different sample types. All test‑process parameters, statistical results, and raw image data are fully archived, ensuring data traceability and result verifiability. Built‑in automatic report generation and multi‑format data export interfaces facilitate quality‑system management and the dissemination of research findings. Standardized operational logic and a robust access‑control mechanism enhance data consistency and security in multi‑user environments.
Reference standard:
This product complies with the new national standard GB/T 21649.2—2025/ISO 13322-2:2021, “Particle Size Analysis—Image‑Based Methods—Part 2: Dynamic Image Analysis,” as well as China State Railway Group’s Technical Specifications for Manufactured Sand in Railway Construction (Q/CR 9570) and the Specification for Manufactured Sand Used in Railway Concrete (Q/CR 865), among others. It enables production monitoring of both dry‑ and wet‑process manufactured sand. Laboratory testing of parameters such as roundness, length‑to‑diameter ratio, and fineness modulus is also supported (for dry‑process applications).
Performance Verification:
To ensure the consistency of measurement results with recognized standards, we perform calibration verification using a certified 46# corundum reference material. Testing has demonstrated that the D50 measurement error for this reference material is better than ±1%.
2. Repeatability
The consistency of results obtained from multiple measurements of the same sample under identical conditions. It provides stable and reliable data, typically with a relative standard deviation (RSD) better than ±1%.
