Concrete Floor Grinders

Concrete Floor Grinders

Niagara Machine has the concrete floor grinding and polishing equipment you need. 

Looking for a concrete floor grinder and polisher to grind and polish the concrete surfaces on your commercial or industrial restoration project? Niagara Machine has what you need. We offer an extensive inventory of concrete grinding machines for surface preparation, coatings, resin, and epoxy removal. As well as polishing concrete, terrazzo and overlays. Check out the latest models of concrete grinders from Lavina, DiamaPro Systems, and Terrco. 

Concrete floor grinders are available in various sizes and types, ranging from small handheld models for small-scale projects to larger walk-behind or ride-on machines for larger areas. They are versatile tools that can be used for aggressive grinding to remove coatings, adhesives, or uneven surfaces, as well as for fine polishing to achieve a smooth and glossy finish.

A planetary grinder is a concrete grinder that uses three smaller rotating heads that simultaneously spin while the entire unit itself is also rotating. This technology helps the machine to cover a wider surface area with less effort and can be very efficient. The triple head design gives the grinder more control, resulting in a smoother and flatter finish.
 
On the other hand, a direct drive grinder is powered by a motor directly attached to the grinding disc or wheel. This direct link results in the wheel turning at the same speed as the motor. It tends to be less complex, smaller, lighter and thus easier to handle than planetary grinders. It is good for edge work, small jobs, or residential and small commercial use.
 
When choosing between these two, consider factors like size of the job, surface flatness requirements, power and precision needed. Planetary grinders are typically used for bigger industrial jobs or where more control is needed, while direct drive grinders are often better suited for smaller jobs or for precision work.

When it comes to a complete range of power, Lavina offers some of the best planetary floor grinders on the market. Lavina concrete grinders include electric, propane, self-propelled, edgers, and remote-controlled machines that offer a diverse range of use including grinding and polishing of concrete surfaces, natural stone, terrazzo, and overlays. If you need a floor grinder for virtually any surface or in any environment, Lavina is the brand for you. 

Terrco is another trusted name in grinding and polishing. With a direct drive design specifically for terrazzo polishing, their concrete grinding machines have since been adapted to handle floor grinding and polishing of concrete surfaces. This new adaptation has made Terrco a key brand in commercial and industrial restoration. 

Air Purification

Grinding concrete, natural stone, and terrazzo dry naturally create dust, which can be an OSHA violation. Take compliance issues off your mind with DiamaPro’s air scrubbers, vacuums when grinding dry. Grinding wet can create concrete slurry that needs to be disposed of while meeting OSHA standards. DiamaPros slurry containment system helps you get rid of slurry safely and easily. 

What is Concrete Grinding & Polishing?

When you need to prepare a concrete surface for restoration, you first need to grind down the concrete until smooth. A grinder uses tooling to smooth the surface of the concrete. The tooling comes in various types from metals to resins and in various grits depending on the level of grinding needed. Concrete grinding and polishing is a common part of commercial building restoration, and the concrete polishing equipment you choose is an important step in that process. 

Grinding machines are typically used for grinding concrete, but they can also be used to grind natural stone and terrazzo which is a floor composite that is most commonly found inside commercial buildings.

Browse through our floor grinder and floor polisher inventory to find the right size and fit for your job. For concrete grinder repair, call one of our factory-trained technicians for assistance at 800-622-2048!
