Determination of moisture content of bulk fluorite powder
Flow plate experiment
WARNING - Personnel using this standard should have practical experience in formal laboratory work. This standard does not indicate all possible security questions
question. It is the responsibility of the user to take appropriate safety and health measures and to ensure compliance with the conditions set forth in the relevant national regulations.
1 Scope
This standard specifies the method for the determination of the moisture content of bulk fluorite powder.
This standard applies to the maximum particle size of 1mm bulk fluorite powder in the determination of moisture content limit, which is less than 150μm particle size
The particle composition is 80% (mass fraction) or more.

3 terms and definitions
The following terms and definitions apply to this document.
3.1
Bulk fluorite powder fluorsparpowderinbulk
By the fine powder, small particles (maximum particle size of 1mm) composition, the main component of calcium fluoride (CaF2), no packaging, directly into the ship's goods
Place without any intermediate enclosure.
3.2
Fluidized liquify
There is a certain proportion of fine particles and a certain amount of moisture in the bulk fluorite powder, in the vibration, impact or ship movement and other major external forces under the influence of loss
Internal shear strength of the phenomenon. In the experiment, the samples were produced by the external force vibration, the sample water content and the dense state of the sample
Changes in the saturation of the plastic deformation occurs.
3.3
Flow water points flowmoisturepoint
FMP
The sample produces a flow state, ie, the mass fraction (%) of the moisture content when fluidization occurs.
3.4
Proper transport of water transportablemoisturelimits
TML
Use of non-special provisions of the ship transport, bulk cargo can be safely transported the highest water content, also known as the transport water limit.
