Concrete grinding machines are used to clean concrete and to remove coatings, epoxy, oil, chemicals, or paints from raw concrete. These machines are used for smoothing out bumps and other irregularities in both horizontal and vertical concrete surfaces. Concrete grinding machines work by using a grinding disc or wheel that is usually embedded with diamond chips. These abrasive media help to cut the surface that is being designed to remove paint, coatings and surface contaminants. ใบเจียร
Available in a wide range of configurations
To match specific job requirements, concrete grinding machines are available in a wide range of configurations. They are hand-held, dustless, walk behind, single head and multiple head.
Hand-held Grinders- They are the small grinders used specifically for edge work and for small jobs. Available in a dustless mode, they are usually 5 or 7 inches in diameter with a single head. It could be one of the most versatile and useful items in your tool chest. One can also use them to clean paint or irregularities from small sections of concrete. It can remove graffiti and worn coatings or paint and to roughen up floor surfaces in preparation for coating application. However, these machines can’t replace walk-behind surface preparation machines for large areas of concrete. But, they work excellently in tight areas where the larger machines can’t maneuver, such as in corners and close to walls.
Multiple-Held Grinders- Multiple-held grinders use horizontally rotating discs to perform a multitude of tasks. The key to their versatility are the grinding attachments. These grinding attachments are available in a variety of types and grits to suit different applications. They leave behind a smoother profile and while working on hard surfaces, they may polish rather than abrade the surface.
Dustless Grinders- While, dustless grinders use a dust shroud to separates dust collection system. This machine saves your time on cleanup, and allows other trades to perform in the same area at the same time. This is the best combination of grinding tools that will result in maximum performance and flexibility for minimum cost. You will need to own a good vacuum dust collector which is powerful and small with self-cleaning filters that vibrate to remove the concrete dust.
The following recommendations are for the contractors who are starting a business in this lucrative field of concrete grinding or who are just starting up and need the grinder and abrasive to prepare concrete floors.
