Read OnDry grinding requires approximately 30 % more energy / wt. of ground material. Dry mills need more mill volume than comparable wet mills. However, the increased metal wear of the grinding media and the mill liners for wet grinding, equalizes the additional energy costs of dry grinding procedures ~ 30 - 40 % of wear costs in wet grinding.
Read OnSelecting the correct angle grinder for concrete grinding purposes is very important. You can choose either a 4-inch angle grinder or one that is 4 ½ inches. These are considered the best for most concrete grinding tasks. It may also be a good idea that you choose a tool with a motor that is able to draw anywhere between 5 – 9 amps.
