中铝广西分公司氧化铝厂原料车间针对7#B铝矿皮带卸料小车长期存在的堵料、漏料问题，通过结构优化与材料升级完成改造，显著提升设备运行效率。

改造前，梯形分料口因易损部位磨损导致堵料、漏料频发，增加维护负担并影响生产连续性。

改造中，专项小组采用双重方案：一是结构优化，割除原易损部位并焊接盒状新结构，将下料口水平直边改为圆弧设计，底部增设封堵钢板形成 "漏料自缓冲" 机制，保护斜边焊缝；二是材料升级，以耐磨钢棒替代原有钢板，提升抗冲刷能力。

改造后，设备抗堵料、漏料性能显著增强，结疤隐患消除，已连续稳定运行112天，漏料问题基本解决，岗位清理维护工作量减少70%以上，预计年节约成本超200万元。该项目为氧化铝行业同类设备改造提供可复制模板，推动设备向高效、耐磨、智能化方向升级。
