Device for controlling the separation of the foam concentrate from the pigeons rock in a flotation apparatus

摘要

the device has a measuring device (5) for liquid level and density in the cell of the flotationsapparates, in which two druckluftmischrohre (6, 7) with a druckdifferenzgeber (10) are connected to a controller (28) of the flow rate of the schaummittels and a korrekturglied (13) is connected.which is also a one of the druckluftmischrohre (6) thrusters (11) is connected.the outcome of the limb (13) to a control circuit (17) to the members of fu00fcllstandsstabilisierung tru00fcbehu00f6he controller (18) for the flow of the water with the foaming by the outcome with a control valve (20) is connected with the output of a signal according to the deviation of the tru00fcbehu00f6he from set point is generated.the durchfluu00dfgeber (22) in the water with the foaming is a control circuit (17) or controller (23) connected to the throughput of waste rock, the outcome with the drive (26) of a regelventils (27) is connected with a signal to this exit after the abweic hung the flow of water with the foaming of the set point is generated.
