Concrete Grinders

A concrete grinders can come in many configurations, the most common being a hand-held Angle grinder, but it may be a specialized tool for countertops or worktops. All concrete grinders use some sort of abrasive to grind or polish such as diamond tools or Silicon carbide. Concrete is usually ground dry for convenience, because it can be done with fewer people than wet grinding although a HEPA filter-equipped vacuum is needed to capture the fine dust produced. Of course concrete can also be ground wet in which case no vacuum is used. Fine concrete dust contains silica which is very harmful to the lungs and can lead to silicosis so all effort should be made to avoid breathing concrete dust. For green building methods many have seen the benefit of using concrete grinders that are designed for wet grinding. These machines do not require electricity and are run on alternative fuels.

A concrete grinder is used for a number of reasons such as removing things like paint spills, glue, imperfections in concrete work, smoothing uneven surfaces, removing formwork seams or protrusions. Some of the types of concrete grinders available are:
• Shrouded concrete grinder with vacuum. This particular grinder is used for cleaning of planning and removal of glues and paints from concrete work. It is also ideal for smoothing uneven surfaces. The three different sizes available are 5, 7 and 10 inch models. A dust vacuum is used to stop dust and help remove debris while you are working.
• Heavy-duty grinders. 7-inch heavy duty angle grinders for concrete applications are made especially for concrete work. They are mainly used for removing blemishes or cleaning the concrete surface. Make sure there is a dust collection device included with the model.
• 5-inch concrete surface grinder. This model will refurbish and deburr concrete, remove irregularities, form-work seams and any protrusions. There is a built in dust chute with most models that will remove dust and debris. This type of concrete grinder only weighs 6 pounds, making it ideal for reducing worker fatigue.
• Hand held grinders. These are ideal for small jobs like areas close to walls and other hard to get places. They are also ideal for removing blemishes to concrete work. They are very light and easy to use. If you have a large area to cover, a hand held grinder may be a little impractical.
• Multi headed grinders. These models come with dust collectors and are designed for large areas. Their main purpose is to level and remove small imperfections to concrete work. The brushes used in multi headed grinders can be changed to suit the surface.

When choosing a concrete grinders, the first thing to consider is what you are planning to use it for and the size of the job you will be doing. If you are only using a large industrial grinder once it may be a cheaper alternative to rent a machine. If you only need a small hand held concrete grinders, it may be a good idea to buy one.
