The mortar and pestle are made of agate stone from Brazil and it is the best agate stone in the world due to the highest
When removing large amounts of material, using a 120 or coarser grit will get the job done more quickly than, say, a 150 grit wheel. And while vitrified bond aluminum oxide wheels are the go-to for general purpose work, shops grinding hardened tool steel and other difficult materials should consider investing in a resin bond ceramic or CBN wheel.
30-08-2022 · The wear of grinding steel balls is related to the surface area of steel balls. In general, the steel ball in the grinder has both impact and abrasion effects, so the wear is proportional to the n power of the diameter of the steel ball, and the value of n is between 2 and 3. Table 1-11 The Relation between Steel Ball Diameter and Material Size
