DISPERSION
the moving grinding material, which is activated by a high speed and high energy agitator. As the grinding material collides and rolls about each other, the solid particles get caught between them and are gradually reduced in size. Each primary particle or aggregate in the finished product is the result of billions of bombardments by the grinding

Effects of Grinding Passes and Direction on Material ...
A threedimensional finite element model of rail grinding was established to explore the effects of grinding passes and grinding direction on the material removal behaviour of grinding rails during the grinding process. The results indicate that as the number of grinding passes increases, a decrease in the grinding force reduces both the amount of removed rail material and the surface roughness.

Solo XP Grinding : elderscrollsonline reddit
What is the fastest way to grind to 50 solo? Spell Scar works pretty well kind of like Skyreach with easier pulls. Personally I hate the feel of grinding though, so I do the daily random dungeon route, complete the dungeon and only dropping from party after two others have and then letting game kick me... watch what that does to the xp reward ;).
