The most obvious difference is the use of water while grinding and the non-use of water, that is where the wet and dry name comes from. The wet concrete grinding process. The concrete wet process uses water, which is relatively accessible. The water cools the diamond tooling by acting as a lubricant to reduce friction.

A nitric-hydrofluoric acid blend is the most widely used acid pickling solution. Acid concentration, solution temperature and contact time need to be carefully controlled during this process to ensure parts are not overpickled. Over-pickling can result in damage to the stainless steel that would result in loss of corrosion resistance.

Abstract The effects of dodecylammonium chloride on properties of quartz slurries that are relevant to grinding, such as pulp fluidity, flocculation and dispersion, and primary breakage, have been investigated in this study. These tests were conducted under chemical conditions (pH, ionic strength, additive concentration, etc.) similar to those used in wet ball milling tests.

Wet grinding systems need dewatering units with a thickener and filter, while dry grinding systems requires pre-wetting units. Pre-wetting is usually associated with dry grinding. Pre-wetting includes addition of an adequate amount of water homogeneously into the dry-ground material to prepare pre-wetted material suitable for balling.

Therefore, wet grinding is a better alternative. In this study, we made several types of grinding wheels, performed the wet grinding of stainless steel sheets, and identified the wheels most suitable for the process. As such, this study developed a special accessory that could be attached to a wet grinding workpiece.

On the other hand, dry polishing requires no water. During the initial phase of the grinding, wet polishing machinery is used to grind most of the concrete. When the surface becomes smoother and appropriate for the wet grinding, the workers change the blades from metal-bonded to the diamond abrasive for fine grinding and more sheen & smoothness.
