PTMS magnetic separation

what is magnetic separation in Feldspar？

Iron removers are common in some minerals and they are capable of separating mineral impurities. There are several types of iron remover:

Wet strong magnetic iron remover

Wet/dry low strength drum

Induction roller type iron remover

Lifting roller remover

Cross belt iron remover

Disc iron remover

Rare earth drum

Rare earth magnetic roller

Wet strong magnetic iron remover

The Foshan Wanjiade plant is an expert in the manufacture of such iron separators, which are commonly used to recover/remove ilmenite from HMC prior to dry separation. Ilmenite is usually required to have a low TiO 2 content (about 50%) and thus has a high magnetic susceptibility.

The reading device consists of a rotating conveyor belt that is influenced by the magnetic field generated by the surrounding electromagnets, followed by a magnetic field without magnetic influence. The magnetic particles are initially held in the plate, while the non-magnetic particles are washed into the underflow cell. When the plate is in a non-magnetic field, the magnetic particles are then washed away into a separate flow cell below.

No magnetite (will hang in the board/matrix)

Contains no +1mm particles (will block the plate/matrix)

Have a clean and constant high pressure water supply

Stable feed rate and density

The field strength (indirect measurement and adjustment control through the electromagnet's amplifier) ​​is typically as high as 15,000 Gauss.

Washing position and flow

Board gap (usually 2mm)

Product separator location

For 16-pole units, the feed rate is usually 25-30tph

Wet/dry low strength drum

Wet iron removers, which are commonly used to recover/remove magnetite from HMC prior to high strength wet or dry magnetic separation.

For wet iron removal, there are two models, countercurrent and cocurrent. All iron removal consists of a rotating drum in which a permanent magnet is fixed. It is fed to the immersed portion of the drum in the form of a slurry flowing through the bath, and is attracted to the surface of the drum by the magnetic field depending on the magnetic susceptibility of the particles and is not affected and discharged therefrom. Bathe with the slurry. As the drum rotates, the magnetic particles exit the magnetic field and are typically discharged separately by means of a doctor blade/brush.

The dry feed is distributed on the drum at the top. When the drum rotates into the magnetic field of the permanent magnet, the non-magnetic particles are unaffected and discarded by the centrifugal force, while the magnetic particles remain on the drum surface until they leave the magnetic field and fall or are scraped separately. Drop it.

Operational variables:

Drum speed

Split position

Magnet position

Induction roller type iron remover

These dry iron removers are commonly used to separate ilmenite from magnetic and non-magnetic properties in a dry mill.

The electromagnet generates a magnetic field on a serrated rotating roller through a closely spaced cast iron rod. The dry feed is distributed on the surface of the roll at the top and distributed over the surface of the roll, wherein the magnetic susceptibility of the particles is maintained on the roll or discharged due to the centrifugal movement of the rolls. The machine has two parallel feed points, each having two rollers mounted vertically on top, and the lower roller working as a non-magnetic cleaner.

The manipulated variables are:

The field strength (indirect measurement and adjustment control through the electromagnet's amplifier) is typically as high as 15,000 Gauss.

The pole gap (the closer to the gap of the magnetic field strength) is usually 2 mm.

Rolling speed (usually fixed, adjusted only by pulley and belt change)

Separator position (determined by visual observation of the fan)

Feed temperature affects magnetic susceptibility

Feed rate is usually 2.5tph

Cross belt magnetic separator

The cross-belt consists of a single strip that is distributed over the strip and transported slowly over a series of five electromagnets whose magnetic field lifts the magnetic particles from the strip according to their magnetic susceptibility. Below each magnet is a smaller, faster moving belt that passes through the main belt at a right angle, picking up magnetic particles and outputting them from the magnetic field for discharge into the launder. The gap between the main strip and the magnet is gradually reduced until only non-magnetic particles that are not affected by the magnetic field remain on the main strip and are discharged from the end.

The operational variables include:

The field strength (indirect measurement and adjustment control through the electromagnet's amplifier) is typically as high as 15,000 Gauss.

Pole gap (distance between pole and strip)

Typical feed rate 1.5tph

Disc magnetic separator

These dry separators are similar to the cross belts except that they do not use a leather belt to transport the magnetic material, but instead use a rotating disk. The manipulated variables are similar. Disc magnetic separators are especially suitable for final cleaning.
