Abstract: Many treatment measures for dust are normally taken after the dust produced, which means people pay less attention on preventing the sources of dust than sweeping sedimentary dust. To propose efficient dust control measures in transferring point, firstly, we analyze the characteristics of dust generation. Secondly, based on the research of the sealing dust suppression technology and ultra-fine water mist technology, we propose an efficient control technology. Finally, the industrial testing was employed in the transferring point in a Huaibei coal preparation plant and some relevant parameters were measured.
