The material being ground also helps us determine the grit size. For hard to grind materials, we would recommend a finer grit size because a smaller particle will penetrate hard materials and form a chip easier than a larger blockier one. Difficult or hard to grind materials are abusive to the abrasive grain and can cause them to blunt or dull.

Dust control is an essential but time-consuming part of grinding concrete. Let's look at an example to get an idea of how some of those variables play out and look at the questions of time and slab size. Using a Husqvarna PG 820 RC, a 32" grinder (mentioned above), it's common to grind 7,000 to 10,000 square feet per day.

Hard, brittle materials generally require a wheel with a fine grit size and a softer grade. Hard materials resist the penetration of abrasive grains and cause them to dull quickly. Therefore, the combination of finer grit and softer grade lets abrasive grains break away as they become dull, exposing fresh, sharp cutting points.

However, in the case of smaller fractions (4–8 mm), the impact of the crushing process on the value of the crushing strength indicator is smaller, and, thus, the strength properties of the aggregates (gravel and grit) are less important than in case of the grits obtained as a result of crushing (fraction 10–14 mm).

The abrasive used for each succeeding grinding operation should be one or two grit sizes smaller than that used in the preceding step. A satisfactory fine grinding sequence might involve SiC papers with grit sizes of 240, 320, 400, and 600 grit [P280, P400, P800 and P1200]. This sequence is used in the "traditional" approach.
