Are you planning to buy or rent afloor grinder in order to prepare a concrete floor for tiling or other surface finishes? Read on and discover the unique pros and cons of grinders with different numbers of heads. Use this information as you select the floor grinder with the number of heads that will help you to attain your objectives.
Single-Head Floor Grinders
Single-head floor grinders have one head which exerts an abrasive force on the floor. They have a small footprint and may not be suitable for grinding a large area, such as an entire warehouse floor. However, their small size makes them ideal for working in tight spaces, such as corners and around obstructions (columns, for example). Their rotary disc is controlled by gears. This mode of operation also makes single-head grinders unsuitable for polishing since they leave relative deep marks on floors.
Two-Head Floor Grinders
Floor grinders with two heads tend to have a larger footprint than that of single-head grinders. The machine exerts sufficient pressure on the two heads in order to break up floor finishes, such as epoxy coatings. This equipment is suitable for moderately large spaces, such as the floors in office complexes.
Three-Head Floor Grinders
Three-head floor grinders are the machines of choice when one wants to work quickly in a large space. They have a large footprint which makes work to progress faster than the rate at which equipment with fewer heads can work. The distribution of the machine's weight to the three heads makes this kind of machine suitable for polishing operations.
Four-Head Floor Grinders
Floor grinders with four heads can cover larger areas in a shorter time when compared to equipment with three or fewer heads. Two heads spin in a different direction from the direction in which the other pair of heads is spinning. This makes the machine easy to keep in line. However, this kind of floor grinder is better suited to polishing operations (creating a smooth or reflective finish) since each head exerts less pressure on the floor due to the wider surface/footprint of the machine. It is also harder to use in confined spaces, such as corners and places where the floor meets a wall.
Your choice of a floor grinder should not be influenced by the number of heads on that machine only. Think about the size of the machine as well as the safety features that it comes with. In this way, you will be able to select a floor grinder which will be safe and manageable to operate.Share
