Described solenoid coil, mine tailing flow control valve, feed water brake and concentrate flow control valve with
Electric control gear connects.
Preferably, the distance at the top of the solenoid coil of the bottom of described mine tailing overfall higher than first is about 0.3-1
Coil height again, the number of described mine tailing overfall is 2-4.
Preferably, the spacing of described solenoid coil adjacent windings is 0.5-1 times of coil height, number of coils 4-
9.
The utility model has the advantages that：
The defects of traditional column magnetic separator is sorted the magnetic field reduction of area middle part and big water consumption by flow pattern column magnetic separator in mine tailing is cleverly
With reference to simultaneously complementation, the mine tailing inner flow tube for including mine tailing overfall is set at the middle part of column magnetic separator, had both avoided column magnetic separator sorting area
Middle part magnetic field reduces the defects of causing fine-particle minerals to be lost in, while also overcoming mine tailing in traditional column magnetic separator needs consumption a large amount of
Ascending water could " following current and on " the problem of entering overflow launder, the water consumption of column magnetic separator can be greatly reduced.
