Particle Pollution

Coarse (bigger) particles, called PM 10, can irritate your eyes, nose, and throat. Dust from roads, farms, dry riverbeds, construction sites, and mines are types of PM 10. Fine (smaller) particles, called PM 2.5, are more dangerous because they can get into the deep parts of your lungs — or even into your blood.

Why do wet

Mar 12, 2019This is because the extension of the wet-particles is larger on the faster roll because of the speed difference between the two rolls. Consequently, the adhesion mechanism of the wet-particles in the three-roll mill is proven scientifically to be the force balance due to the liquid bridge force.

The magnetic roll, under which the coolant flows, rotates intermittently. The magnetically attracted material builds up a mass of fine hair-like particles between the magnetic roll and the housing. This accumulation serves as a filter medium to entrap fine non-magnetic particles such as grinding wheel scale or other coolant contaminates.
