VoJa-2910 Intelligent Analyzer for Particle Morphology of Manufactured Sand

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 ultimate strength. VoJa, developed and manufactured by Hongruijia… ^® -2910 Intelligent Particle Morphology Analyzer for Manufactured Sand utilizes machine vision algorithms and AI technologies, coupled with a rigorously designed optical‑physical architecture, to deliver highly accurate, low‑interference measurement data, thereby enabling the industry to transition from vague, experience‑based judgments to precise, data‑driven decision‑making.
Product Features:

Automatic material feeding and AI algorithms enable in-depth analysis of manufactured sand particles, from their appearance to their data; the key features are as follows:

1. High-Definition Dynamic Imaging and High-Speed Processing: Equipped with a high-speed image sensor and an ultrasonic separation system, this technology enables non-contact dynamic capture of particles as they fall freely, effectively preventing particle overlap. Paired with a high-resolution telecentric lens, it ensures a wide field of view and crisp, distortion-free imaging, providing a high-quality image foundation for subsequent analysis. The robust image-processing software leverages advanced edge‑detection algorithms to automatically identify and segment adhered particles, enabling “image acquisition complete—report generated immediately” analysis.

2. Fully automated, intelligent workflow: From sample injection and dispersion to imaging and data analysis, the entire process is governed by standard operating procedures (SOPs), minimizing human error and intervention. Users simply load the sample, and the system automatically executes all steps, generating a structured report. This lowers the technical skill requirements for operators and enhances laboratory standardization and testing throughput.

3. Multidimensional Parameters and In-Depth Analysis: The instrument transcends the limitations of single‑dimensional particle‑size analysis, offering a dual, multidimensional parameter framework that captures both particle size and morphology. It not only measures particle-size distribution—including stone powder content—fineness modulus, and gradation curves, but also quantifies key morphological parameters for each individual particle, such as roundness and aspect ratio, and generates corresponding distribution curves. This enables quantitative assessment of flakiness and elongation indices and detailed analysis of particle sphericity, providing data‑driven insights to optimize crushing processes and enhance the workability and strength of concrete.

4. Repeatability and Reliability: The instrument exhibits excellent repeatability and accuracy, with repeatability errors for key parameters maintained at ≤1%, ensuring stable and reliable test results. Its broad measurement range—spanning 10 to 10,000 μm—enables it to meet diverse requirements, from fine sand to coarse sand. Furthermore, the equipment is designed for durability while minimizing maintenance needs, thereby guaranteeing long-term, stable operation.

Reference standard:

This product complies with China State Railway Group’s standards, including the “Technical Specification for Manufactured Sand in Railway Construction” (Q/CR 9570) and the “Manufactured Sand for Railway Concrete” (Q/CR 865). It supports production monitoring of both dry‑process and wet‑process manufactured sand. Laboratory testing is available for parameters such as roundness, length‑to‑diameter ratio, and fineness modulus in the dry process, as well as in the wet process.
