The control of feed water content is very important for the stable operation of vertical grinding machine. Taking the production line of heavy calcium powder as an example, if the moisture content of raw material is too large, the new material will bind the fine powder on the feeding bed, resulting in the formation of cake on the grinding disc.
Pigment Powder Grinding minerals is a time consuming process. However, the grinding process demonstrates the importance of hardness and streak versus color in choosing pigments for paint; some in-class mineral grinding is necessary to achieve the learning objectives.
The nature of grinding aids means that they promote the formation of dust because they reduce the agglomeration of the finest particles (see Figure 3). In certain cases, the filter and/or the hopper of the bag filter can become overloaded. This can lead to the wrong supposition that the grinding aid chemically attacks the filter cloth.
This powder has the ability to absorb moisture, absorb oils, absorb odor, serve as a lubricant, and produce an astringent effect with human skin.
