what is magnetic separation in Kaolin?

Precautions for iron removal operation:

(1) When selecting the location where the iron remover is installed, the following principles should be followed:

a) selecting an iron remover with appropriate magnetic field strength according to the type of ferromagnetic substance;

b) The iron removal should be carried out in the selected raw materials to prevent larger particles and other impurities from entering the surrounding iron trough, and hinder the effective performance of the iron remover;

c) Iron removal should be as low as possible to extend the life of the magnet;

(2) Because the price of high and low temperature magnetic rods is different, the magnetic rod should be selected reasonably according to the use temperature to achieve economical use.

(3) The oxidation of the magnetic rod will cause the magnetic field to weaken, so the magnetic source carrier must be cleaned when the iron remover is deactivated. When purchasing the iron removal rod, be sure to check whether the seals at both ends are intact or not. Leakage prevents the core from contacting the slurry to oxidize or corrode and demagnetize.

(4) Cleaning the magnetic rod is the key to ensure the iron removal effect, especially the high gradient magnetic field, its radial attenuation is faster, and the effective magnetic path is shorter; only when the working surface of the iron magnetic rod is cleaned in time, the magnetic field can be normally played. The role of the gradient. The cleaning distance should be based on the amount of iron in the slurry combined with empirical data.

(5) According to the influence characteristics of ferromagnetic substances on ceramic products, analyze the source and seriousness of ferromagnetic impurities in products, and then adopt appropriate treatment measures to block the source of impurities.

(6) The height of the slurry section of the permanent magnet slurry trough interceptor should be appropriate, and the ferromagnetic impurity of the uppermost layer should be basically guaranteed to be within the effective magnetic range.
