relationship between the amount of moisture absorbed by each sample and the intensity of the non-bonded – OH band at 1900 nm, indicating the possibility of using this region for quantitatively prediciting moisture content in oil shale and other mineral matter. However similar trends were not observed with the –OH bands at 1400 and 2200 nm.

Does the moisture content of the stone affect the raymond ...

In the process of grinding stone by high pressure pulverizer, if the water content of stone is too large, it is easy to cause the powder to stick in the grinding chamber due to the high humidity when the stone is crushed.As more and more stone powder is attached, the rotation speed and pressure of the raymond mill will become larger and larger, which will eventually reduce the grinding output.

Types of Casting Defects in Sand Casting African

However, a common cause of the above defects is the use of casting sands with reduced permeability, strength and high moisture content. This highlights the importance of using appropriate sands in the sand casting processes. While some green sands and dry sands stand out in strength, they do not satisfy all requirements of good casting sand.
