drum magnetic separator
The process of producing PTMS magnetic separator from coal measure kaolin using coal gangue to produce paper coated kaolin mainly consists of two parts: pulverization superfine process and calcination whitening process. Grinding ultrafine process is an important link to determine the quality of kaolin.
PTMS magnetic separation
The process of producing PTMS magnetic separator from coal measure kaolin can be divided into sintering before grinding and sintering before grinding. Compared with the two technological schemes, each has its own advantages and disadvantages. High whiteness products can be obtained by grinding and burning process, because micron size calcination is more complete, and iron oxide can be whitened by whitener reduction in calcination operation; Another advantage is low hardness of raw ore and low ball consumption in ultra-fine grinding. The existing problem is that the grinding concentration is low and the number of equipment required is large.
what is magnetic separation in chemistry?
In addition, after calcination, the fine particles are easy to bond, even sintering, so that the originally qualified particle size coarser, in order to ensure the qualified particle size requirements also need to be ultrafine grinding, drying, to complicate the process. The sintering before grinding process ensures qualified particle size. The PTMS magnetic separator process is relatively simple. The disadvantage is that the grinding after burning has high hardness and increased ball consumption. The regrinding after calcining operation makes the whiteness of the product 1%~3% lower than that of the grinding after burning process, which requires higher ore quality.
