Series RCDPS which can work continuously remove iron pieces from magnetic ores by the structure of compounded magnetic field. Their functions include attracting, separating iron from ores, recovering and discharging with the principle as follows: when finding a passing iron,  the metal detector will send a signal at once to program control unit, which thus produce a strong excitation and then will attract the iron pieces which have been sent to the bottom of the separator, while at the same time some ores will be attracted inevitably as well. Both of them will be sent to the weak area where magnetic ores can not be attracted and will drop down onto the conveyer belt for the second recovery, while the iron pieces will go on moving to collecting box finally. Compared to series RCDP, this series can work continuously and we don?? need to stop it when remove iron pieces. What?? more, they don?? need junction platform, as RCDP require, so they occupy less space owing to the horizontal setting of separator and the belt.They are suitable for removing material from magnetite, sintered ores and ball ores. When non-magnetic iron pieces exist in the ores (like high manganese steel),Please set another metal detector at the tail of the separator, through detecting, warning, locating, thus the iron pieces can be removed manually after stopping the equipment.
