我矿学习外地经验,经多次改进,设计安装了一台间热竖式烘矿炉,使用效果较好,它与我矿原有使用的φ500×4000回转干燥机、内筒体为锥体(φ950×2000)和外筒体为圆筒(φ1000×1800)的竖式烘矿炉比较,各项指标都有所提高(见下表)。现在使用的间热竖式烘矿炉的结构很简单。用φ1000×1500废棒磨机筒体与8.5毫米钢板卷制焊接的锥体(高700毫米)连接成内筒体,外筒体是钢板卷制焊接的圆筒体,其下部直径1100毫米、上部直径1300毫米、高2000毫米,外筒体上钻有很多
I learn from the field of mine experience, after many improvements, the design and installation of an indirect vertical drying furnace, the use of better, it used mine with my original φ500 × 4000 rotary dryer, the inner cylinder cone (φ950 × 2000) and the outer cylinder is cylindrical (φ1000 × 1800) vertical bake furnace, the indicators have increased (see table below). The structure of the indirect hot bake furnace now used is simple. With φ1000 × 1500 spent rod mill barrel and 8.5 mm steel cone welded (700 mm high) connected to the inner cylinder, the outer cylinder is rolled steel cylinder, the lower part of the diameter of 1100 mm, The upper diameter of 1300 mm, height 2000 mm, a lot of drilling on the outer cylinder
