Single head concrete grinders are low cost to hire, relatively aggressive and easy to handle, but they do leave grinding shoulders otherwise called tool marks which appear as rings when the concrete is wetted or when a sealer is applied. Larger diameter grinding wheels will leave a flatter finish with less tool marks than smaller diameter grinding wheels, however they will not grind to the bottom of depressions as easily which could leave the floor with many small areas where the floor has not been ground. Double head concrete grinders are faster than single head grinders because they cover more area with the downside being that they are much heavier to move around and consume more electric power. These concrete grinders are mainly used for general flattening or cleaning of concrete, or they can be used for exposing the aggregate while they are usually not suitable for polished concrete.
Planetary concrete grinders leave very few tool marks because they have either three or four grinding wheels turning clockwise and these are connected to a turntable that turns anti clockwise. The four head machines have two of the heads rotating clockwise and the opposite two rotating anti clockwise as well as the turntable rotating and these have the advantage of being very smooth to operate with almost no lateral forces that would require physical effort to control. These machines are ideal to achieve polished concrete with their smooth grinding finish and the ability to easily replace the diamond grinding wheels to move through the different grit sizes.
Another type of concrete grinder is the eight wheel, flat type with four of the grinding wheels rotating clockwise and four rotating anti clockwise. These machines also produce excellent results for polished concrete or just for preparation of concrete floors for cleaning or for coatings application. They are also designed for quick and easy replacement of the grinding wheels and do not suffer from lateral forces like the three headed planetary machines or the single headed machines.All of the above equipment can grind floors easily except for the corners and edges. The edges require an edge grinder that can place the grinding wheel against a wall and run along the wall to even the grinding up to the edge. There are walk behind concrete grinders for this purpose that have either adjustable wheel tracking axles at the rear or a grinding head that can swing to the left or right to enable the grinding wheel to run along the wall while the concrete grinder is move parallel to the wall.
Smaller concrete grinders obviously cover less space and will make your work take longer, but there are pros to having a smaller sized grinder. A smaller grinder can fit into smaller hard to reach places. It can also be a good fit for you if you have a small vacuum. With large machinery, the grinder will work too fast, shoot dust particles everywhere and cause many stoppages if the vacuum isn’t large enough. These dust particles are very tiny and can cause unwanted dirtiness.Another way to help prevent fine dust from filling your project area is by using a dust shroud. This shroud is on the grinding wheel and prevents dust from flying around when used properly.An interesting bit of information on Concrete grinder size is that a 7-inch grinder is 20 times slower than a 10-inch grinder. 3 inches doesn’t seem like a lot, but in this case the speed is much quicker for the extra cost of the bigger size. Concrete grinders do many things for you, just pick out the size and style you want and your flooring will be looking great in no time.
