Application of Raymond mill in kaolin processing and iron removal process

Kaolin is a very important clay mineral, white also known as dolomite, which is widely used in ceramics, paper, paint, medicine, chemical and other applications due to the physical properties of plasticity, good burn resistance. Kaolin raw ore contains feldspar, iron minerals, quartz and other organic substances, such as to produce high quality to meet the various industry sectors of the powder, in the process of grinding and processing by the Raymond Mill can be used to gravity hydraulic classification, high strength magnetic separation, flotation, bleaching and other kaolin processing to improve the purity.

1. First of all, the first crushing stage of the raw ore, a step to the coarse grading process, the use of spiral analyser or vibrating screen on the quartz, feldspar and other coarse grading sand;

2. Secondly, after the powder machine in addition to sand processing, such as processing site is large enough to be stacked to filter out most of the water, and then dried by the dryer to the moisture content of 6% or less into the raymond mill grinding, in the process of grinding the control of the finished product particle size, the selection of mill is the key to the fineness of whether or not the uniformity of the quality of the important factors affecting the quality of the product when the fineness of the fineness reaches 325 mesh and uniformity to improve the quality of the product is better;

3.Finally, after grinding by Raymond mill to remove iron, the material is conveyed by stainless steel spiral to the high magnetic magnetic separator for secondary iron removal to improve the high degree of purity, for the finished product in addition to iron can be packaged and other needs to deal with.

Kaolin milling iron removal process seems complex is actually very simple, the equipment used is similar to the general milling production line, the principle is the same, such as jaw crusher, vibrating screen, belt conveyor, Raymond mill, electromagnetic vibration feeder, dryer, screw conveyor, high magnetic magnetic separator, etc., you want to magnetic separator, etc. is not commonly used in the general ore milling, generally for the removal of iron ore containing iron! This is also the special feature of kaolin milling production line.
