什么是光学分选机？
光学分选机是一种自动化分选系统，利用光学传感器根据颜色、亮度和物料差异识别并去除不需要的颗粒。在矿物加工和回收工厂中，它通常安装在破碎和筛分之后，用于分离传统设备无法检测的异色、受污染和低品位物料。.
光学分选机可处理0.5–50 mm的颗粒尺寸，产能取决于物料特性、入料条件和设备配置。该系统结合CCD/NIR传感器、LED照明、信号处理单元、气喷装置以及溜槽或皮带入料系统，以实现稳定的分选性能。.
适用物料
色选机利用CCD相机和光谱传感器检测颜色、形状和物料差异，去除传统筛分或密度方法无法分离的不需要的颗粒。该设备广泛应用于矿物提纯、玻璃回收、骨料分选和工业物料提纯，包括石英、硅砂、长石、萤石、方解石、再生玻璃及其他有价值的资源。.
应用与物料分选
在矿物加工中，光学分选机可去除铁染、深色和低品位颗粒，以提高纯度、白度和产品质量。石英和硅砂可达到99.5–99.9%的SiO₂纯度，适用于玻璃、半导体和光伏应用，而长石、萤石、方解石和滑石则可受益于颜色和品位控制的改善。在回收和骨料应用中，该设备可从再生玻璃、煤炭、碎石和工业矿物中分离陶瓷、石块、风化颗粒和污染物，以提高回收价值和最终产品质量。.
工作原理
光学分选机通过将每个颗粒的光学特征与预设参考标准进行比较，识别并去除不合格颗粒，然后触发精确计时的气喷将不合格物料分流。与按尺寸或密度分选的机械分选不同，色选基于表面光学特征工作，因此能有效分离尺寸相同但成分或质量不同的颗粒。.
典型流程：物料通过振动给料机进入 → 颗粒在溜槽或皮带上单粒化排列 → CCD/NIR传感器以每秒超过50,000次扫描的速度进行扫描 → 信号处理器标记不合格颗粒 → 压缩空气喷嘴（0.4–0.6 MPa）喷射以剔除不合格物料。入料一致性直接影响精度：颗粒尺寸不规则会导致检测重叠，而表面水分超过1.5%会降低传感器读数并增加误剔率。.
