After that keep on increasing the grit size of the metal-bonded diamond and keep on grinding. Now increase to a 150-grit metal-bonded diamond. This size of grit can be used if a finer look is desired. After grinding with the 150-grit diamond, you must apply a chemical hardener to densify the concrete surface. Now you can start the polishing.

6.Consider the type of abrasive. Abrasives come in varieties, and as such, they should also be an essential factor when you're looking to select a concrete grinding disc. Abrasives have different properties when it comes to strength, hardness, impact resistance, and fracture toughness.
A 10 MW cement mill, output 270 tonnes per hour. A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement. Most cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

In terms of mill type, the answer is almost always vertical roller mills (VRMs). Over the last few decades the industry has been gradually moving towards the use of VRMs for both raw and cement grinding, due largely to the reduced energy consumption compared to ball mills: a saving of between 30 and 50%.
Within the study 3 grinding aids and 3 mixed products (grinding aid-strength enhancer) were tested around a cement grinding circuit at the same cement type (CEM II A-M (LW) 42.5 R). In this type of cement the raw meal includes clinker, limestone, fly ash and gypsum.
