As well the consideration of production costs and carbon footprints, one key issue is energy consumption. For reference, the grinding process represents a significant part of a cement plant's electrical demand, in the range of 50 – 70% of the total integrated plant's needs. Therefore, limiting grinding power demand is a major industry focus.
Concrete grinding is the process of smoothing rough concrete surfaces. During the concrete grinding process, an abrasive tool with diamond attachment smooths the rough surface. All coatings, stains, and surface cracks are removed along with the top layer of concrete during the first step in the process. Deeper cracks must be evaluated.
Smoothing the Surface with a Grinder. 1. Test the concrete with MOHS hardness picks before renting a grinder. Choose a …
