First, determine the hardness of the concrete to select the right diamond grains. Start with a lower grit for more aggressive grinding and move to higher grits for a finer finish. Ensure the machine is set up with the appropriate tooling, and always maintain control, making multiple passes for a consistent result.
Wet Grinding. Wet grinding uses water and specialized tools to grind down concrete surfaces. This method is best for concrete floors in larger areas and provides a more aggressive grind than dry grinding. The Onfloor 16S-H Planetary Grinder can be used for wet grinding projects (as well as dry), making it a versatile choice for contractors.

The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 4-5% gypsum and possible additives, into the final product, cement . In a modern cement plant the total consumption of electrical energy is about 100 kWh/t . The cement grinding process accounts for approx. 40% if this energy consumption.
While the grinding aids had only a marginal effect on the grinding of quartz, they had a significantly beneficial effect on the grinding of limestone and cement clinker. Triethanolamine appeared to be the most effective of all the aids studied. In the grinding of cement clinker, gypsum also acted as a very effective grinding aid.
