Material sorting equipment quality appraisal

material sorting equipment is based on the core principle of multi-modal sensing and intelligent decision-making algorithms. By optimizing optical recognition accuracy, mechanical actuator response speed and AI sorting accuracy, it achieves efficient sorting of complex materials, impurity removal and resource recovery. It is widely used in mining sorting, renewable resource recovery, food processing and electronic waste processing and other fields. In mineral processing, it is used for intelligent selection of high-grade ores; in the recycling industry, it meets the needs for accurate separation of PET bottle flakes and metal impurities; in the food field, it ensures the real-time removal of moldy particles in grains. Compared with traditional sorting equipment, the new equipment has the characteristics of multi-spectral fusion, adaptive learning and low energy consumption, and is the core equipment of circular economy and intelligent manufacturing.

Zhongke Testing is a product quality appraisal service organization registered with the court. It can provide quality appraisal services for material sorting equipment. It has a professional appraisal team and advanced instruments and equipment to provide fair and accurate appraisal results for the quality appraisal of material sorting equipment.

As the requirements for refinement of sorting processes increase, related quality dispute cases have increased significantly. The judicial dispute focuses on:

1, performance index dispute: whether the sorting accuracy meets the standard, insufficient processing capacity;

2, material defects: optical sensor CCD array bad pixel rate, uneven thickness of wear-resistant coating on sorting nozzle ;

3, process issues: robotic arm positioning repetition accuracy deviation, AI algorithm misjudgment rate;

4, contract performance dispute: core modules (such as the number of bands of hyperspectral imagers, pneumatic actuator brands) are inconsistent with the technical agreement.

The quality appraisal of material sorting equipment usually includes the following steps:

1. Appearance inspection: Check the appearance, surface finish, structural integrity, etc. of the equipment.

2. Component inspection: disassemble the equipment and check whether the size, accuracy, material, etc. of each component meet the design requirements.

3. Performance test: According to the purpose and technical requirements of the equipment, conduct a sorting performance test to evaluate its sorting efficiency, recovery rate, accuracy and other indicators.

4. Material analysis: Conduct material analysis on key components to determine whether the quality, composition and workmanship of the materials meet specifications.

A mining group of the applicant signed an "X-ray Intelligent Sorting Machine Purchase Contract" with an equipment manufacturer of the respondent, agreeing that the ore sorting accuracy is ≥98%. After the operation was put into operation, the loss rate of target minerals in the tailings exceeded 15%. The manufacturer argued that it was caused by the uneven particle size of the ore.

Identification analysis results:

The quality analysis expert group discussed and comprehensively analyzed the relevant information of "material sorting equipment", contract technical agreements, on-site inspection case materials and other data, and made the following quality analysis opinions:

The energy spectrum resolution of the X-ray detector of the material sorting equipment involved in the case is only 120eV (agreement ≤100eV), resulting in mineral feature identification errors; the response delay of the pneumatic nozzle is 0.15s (agreement ≤0.1s), and the dynamic rejection rate is only 85%; the AI training data set does not cover the target mineral symbiotic morphology, and the misjudgment rate reaches 12%.

The appraisal conclusion concluded that defects in the sensing system and algorithm are the main reasons for the sorting failure.

Material sorting equipment quality appraisal report should include:

1, appraisal purpose and reference standards;

2, involved specifications, production batch number, construction record;

3, testing method Methods and equipment list;

4, correlation analysis of test data and failure;
