    摘要: The present invention provides a dry method heavy medium separator adopting a dry method heavy medium separation bed and a separation device. According to the dry method heavy medium separator, a floating material end medium drum screen and a sediment end medium drum screen are arranged below a floating material discharge end and a sediment discharge end of the dry method heavy medium separator and used for separating products from media; a bag-type dust collector is used for collecting dust, a dust collector pipeline is arranged at the top of the dry method heavy medium separator, the air draft volume is larger than the air supply volume during working of the dry method heavy medium separator, the inside of the separator is in a negative pressure state, and therefore dust in the dry method heavy medium separator cannot escape; and the whole system is in a fully closed working state. According to the dry method heavy medium separator adopting the dry method heavy medium separation bed and the separation device, the problems that the fluidization density is instable, the air flow distribution is not uniform in a fluidization process, the medium separation efficiency of an existing medium separation screen for fine materials is low, the magnetic medium content of the fine materials subjected to medium separation is high, and the like are solved, and the medium separation efficiency for fine materials can be improved remarkably.
