摘要

Recycling of fluorescent lamps and broken pieces involves breaking off the pump tube; removing the end socket(s) for sepn. into individual components; tilting the lamp centre tube; drum screening the broken pieces; continuously heating the phosphor to remove mercury; and processing the lamp ends.
