Wet grinding process

Primary Pastes. For the pigmentation of conventional coating systems usually pastes based on mineral spirits are used. To these presscakes produced by the wet grinding process (Section 14.2.2.), aromatic or aromatic-free solvents are added to adjust the aluminum pigment concentration to approximately 65%. 

Bordes et.al. [189] reported experimental results on the use of the Turbiscan On-Line Formal action particle analyzer for monitoring a wet grinding process. 

All pellet processes are typically performed dry, although some manufacturers have used wet grinding processes with an additional drying step, with strict control over the contacting materials to preclude contamination with water or hydrocarbons. The pellets...

For fine pulverization, both dry and wet processes are utilized, but increasingly the dry process is more popular because wet grinding ultimately requires drying and is much more energy intensive. A sensitive fan swirls the dust sizes into the air separator and permits coarse particles to recycle to the grinding mill or be rejected as tailings the fines are drawn into cyclones where the dust is collected. 

Grinding is a continuous process. It may be either wet or dry, but wet grinding (at 50—80% soHds) is most common and requires less power per ton of material ground. Media consumption is significantly higher, however. Wet grinding is also the choice when subsequent processing is wet. In certain...
