Zircon Grinding Requires
Zircon - an overview | ScienceDirect Topics
At high temperatures the following reaction takes place: The dissociation of zircon starts at 1400 °C and at about 1600 °C a complete reaction takes place forming a stable product of zirconia and mullite. High-grade zircon sand is largely used in the foundry industry for moulding.

Using XP Grinding to keep active player bases up instead of releasing new, engaging and compelling content shows a game company, in this case Blizzard, is lazy. Excessive XP Grinding is just bad game design. It also doesn't work. Blizzard made coop mode grindy as hell, and the active player base still dwindled to a shadow of its former self.

Choosing The Right Grinding Wheel | Modern Machine Shop
Usually vitrified wheels are used at speeds less than 6,500 surface feet per minute. At higher speeds, the vitrified bond may break. Organic bond wheels are generally the choice between 6,500 and 9,500 surface feet per minute. Working at higher speeds usually requires specially designed wheels for high speed grinding.

Machining 101: What is Grinding? | Modern Machine Shop
Creep feed grinding is a plunge operation with high horsepower requirements, and which also requires a heavy flow of cutting fluid close to the nip to remove chips and cool the work. Continuous dressing at about 20 to 60 millionths per revolution — preferably with a diamond roll — reduces cutting times and keeps the wheel sharp.

The input range of alumina is proportional to the amount of zircon. Based on literature ( Cook et al., 2016) and ceramic industry interviews, it is concluded that to obtain the same degree of whiteness given by zircon, it is necessary to increase the alumina load rate by at least 50% compared to the zircon share applied.
