本研究旨在研發一燒結生料（Sinter Raw Mix）粒徑與水分量測系統，藉由非接觸式光學影像技術與導電度量測技術開發出一套全世界首創之粒徑與水分分析儀。系統檢測之粒徑大小範圍0.1mm ~ 20mm之間，利用Line Scan CCD來做影像擷取，取像率可達100%，且不會有重複和遺失的缺失，解決過去Area Scan CCD影像遺漏的問題，達到燒結生料粒子全檢功能。此自動化機械包括粒徑整列機構模組、影像擷取模組、影像分析處理模組、水分偵測模組及電控驅動模組，燒結生料經此分析儀將可自動計算出粒徑分佈狀況、粒徑數目、重量百分比與累積重量百分比、燒結生料粒子的形狀係數如：圓形度(Roundness)、球形度(Sphericity)與均勻係數(Uniformity)，且具有良好之重複精度，無論那一個等級其差值皆小於2%，透過水分迴歸分析式可計算出燒結生料的水分含量，提高量測結果之可靠性與準確度，縮短作業時間、減少人為誤差與有效地降低成本，使功能更臻完善。現場操作人員可藉此設備所提供之資訊瞭解到燒結機原料的造粒與水分狀況，並即時做出相關調整，以確保生產之順暢性與提升產能。

An on-line optical scanning system together with conductivity measurement device has been developed for Sinter Raw Mix size analysis and moisture determination. Sinter Raw Mix particle image is obtained by optical Line Scan technology and analyzed by digital image processing. The developed system is composed of pseudo-particle separation module, image acquisition module, image processing module, conductivity measurement module, and electric control module. The main advantages of this system include full inspection (100%) without overlapping nor missing of any particles, which improves the Area Scan Charge Coupled Device (CCD) acquisition problems. The particle size distribution, roundness, sphericity, and uniformity can be obtained by image processing software. The deviation of repeated precision is around ±1%. And converting the conductivity with regression equation to get particle moisture. It has been shown that the developed system has a high accuracy and precision, convenience, and versatile for any kind of particle size, shape, and moisture analysis for the academic and industrial users. Currently two sets of the developed system have been run in Chain Steel Corporation successfully.
