What are the methods for removing iron from ceramics

With the continuous mining of mines and the large-scale use of raw materials, raw materials with good whiteness are becoming more and more tense, and it is difficult to meet the requirements of whiteness or brilliance of products. Therefore, industry professionals are constantly seeking deep processing methods of raw materials to improve raw materials. The value of use.

Ceramic iron removers mostly use permanent magnets. Now electromagnetic slurry iron removers are gradually being replaced, and the effect of electromagnetic is better than that of permanent magnets. High efficiency. Foshan Wanjiade Technology is a manufacturer specializing in the production of various types of magnetic separation equipment. The electromagnetic slurry iron remover produced now has been applied in major ceramic factories and has achieved very good results.

The iron removal process of the prior art mainly uses a magnetic separation method to separate iron-containing minerals in the raw materials. The removal of iron from a magnetic rod is an existing traditional technology commonly used in ceramic factories. As people demand more and more whiteness of ceramic tiles The higher the price, the traditional one-time ball milling and the use of magnetic rods to remove iron can no longer meet the whiteness requirements. Therefore, in order to increase the whiteness of the product, the manufacturers have adopted the introduction of zirconium silicate as the raw material to increase the whiteness. On the one hand, this kind of raw material is expensive, which greatly increases the cost. On the other hand, it can only be applied within a certain range of radioactivity detection standards. Therefore, the scope of use is limited. The method of adding zirconium silicate has actually become a This is a last resort. Therefore, reducing the iron content is the goal that the relevant manufacturers seek to solve. Iron removal methods in ceramic production:

A. Ball mill some of the raw materials except ball soil, and remove iron from the ball milled slurry;

B. The slurry after iron removal is ball milled again, and at the same time, ball soil is added for ball milling. The invention provides a method for removing iron with higher iron removal efficiency, which reduces or even does not need to introduce high-cost zirconium silicate to increase the required whiteness.
