magnetic equipment

The rising momentum of rising water flow is the key factor for separating the medium and poor intergrowth of magnetic minerals and non-magnetic intergrowth of mono-gangue in the magnetic separation column of PTMS magnetic separation machine. The strength of magnetic field in the magnetic separation column can only change the downward velocity of magnetic mineral particles in the ore prize, but can not make the gangue intergrowth escape and separate. Therefore, The adjustment of upflow is the key to the separation of magnetic separation column.

PTMS Magnetic Separator

Since the water pressure in the water supply pipe of the concentrator is stable, the water pressure is required to be greater than 0.17mpa, and the speed of rising water flow is adjusted, that is, the opening size of the water supply valve is adjusted. When the upwelling water flow is large, the monomer gangue and the mesophore in the magnetic aggregate are continuously dispersed by the upwelling water flow, and continue to rise with the upwelling water flow, and finally overflow from the upper edge of the column to become tailings. The greater the opening of the feed water valve, the greater the rising impulse of water, the stronger the flushing effect, the more favorable to improve the concentrate grade, on the contrary, when the rising impulse of water is smaller, the weaker the flushing effect, the more unfavorable to improve the concentrate grade. But the rising impulse of water is too large, the magnetic separation column of PTMS magnetic separator will appear flower phenomenon, resulting in the loss of concentrate, increase the amount of regrinding; The rising impulse of water is too small, the separation effect becomes poor, and the concentrate grade decreases.

what is magnetic separation in science？

The best rising water is to maintain the overflow concentration at 1%~6%, there is a certain amount of ore overflow in the overflow, pulp color is gray yellow to gray white, take a scoop of magnetic separation column tailings dump water, sample scoop at the bottom of a certain amount of ore, ore particle aggregate is gray to gray black, after coaing dry ore particles are mostly intergrowth body. Practice has proved that the overflow liquid level of the magnetic separation column of PTMS is about one finger high from the top of the overflow tank.
