在用回转窑处理铜阳极泥的蒸硒工序中,首先使阳极泥与浓硫酸混合成浆,然后从窑的进料端给入窑内。为了保证炉料在窑内反应良好,除了窑的结构、温度、酸比、负压值等因素外,给料速度也是重要因素之一。此外, In the process of steeping selenium for the treatment of copper anode slime in a rotary kiln, the anode slime is first mixed with concentrated sulfuric acid to form a slurry which is then fed into the kiln from the feed end of the kiln. In order to ensure the charge in the kiln reaction well, in addition to the kiln structure, temperature, acid ratio, negative pressure value and other factors, the feed rate is also one of the important factors. In addition,
