Effect of PTMS Electromagnetic Separator on acidity: The reduction of iron oxide by insurance powder should not be carried out under alkaline conditions. However, the pH value of the bleaching reaction should not be too low, otherwise the stability of the insurance powder will decrease and the decomposition reaction will occur. The test results show that when pH=0.8, as long as 2min at room temperature, half of the powder will be decomposed.

PTMS magnetic separation

Effect of temperature: As with most chemical reactions, the reaction of iron oxide with the increase of temperature is accelerated, but the stability of the powder is greatly decreased with the increase of temperature. When other conditions are well controlled in actual PTMS Electromagnetic Separator production, bleaching at room temperature can also achieve better results.

what is magnetic separation in Kaolin？

The influence of the amount of insurance powder: Theoretically, according to the amount of iron oxide contained in kaolin, the most insurance powder can be calculated, but the actual amount is far more than the theoretical amount. The dosage of insurance powder is generally determined by PTMS Electromagnetic Separator test. In addition, the Fe2O3 content in the kaolin for iron removal bleaching should not be too high (generally less than 1%), otherwise the amount of insurance powder will lead to an increase in the cost of iron removal.
