How to reduce dust when grinding concrete? It is best to use industrial vacuum cleaners, such as the small industrial vacuum cleaner F-65L produced by our company, the medium and large double cylinder vacuum cleaners IVC-33A, IVC-55A, IVC-55L, etc. Secondly, the prevention and control work in the production process is also a good prevention. 1. Wet cutting (water spray)-this kind of engineering control helps eliminate silica dust in the air, and is the most effective dust control method in concrete cutting and grinding. Portable water tank or trolley. Masons should make a plan before arriving at the job site to ensure the resources and manpower required to successfully carry out the wet cutting project. 2. HEPA vacuum and exhaust ventilation system-Industrial vacuum and exhaust ventilation systems are very useful tools when dust cannot be removed from the source. These systems can absorb the formed dust, which is very beneficial for cleaning the site. A high-efficiency particulate air (HEPA) filter prevents the collected dust from escaping the vacuum system. 3. Training-employees should receive comprehensive training on the hazards of silica dust. Training should cover prevention and control methods, respiratory protective equipment, and cleaning methods after get off work. 4. Wear a mask According to the layout of the site, masons and construction workers must wear respiratory protective equipment (RPE). Listed below are the three main types of respirators that can be used in the workplace: Disposable dust mask-can be used in areas where the exposure is up to 5 times that of OSHA PEL. Half-face dust masks – The safe exposure of half-face dust masks is ten times that of OSHA PEL Full-face dust masks – Full-face dust masks can protect workers from OSHA PEL damage by 50 times.

How to reduce dust when grinding concrete？ Keep moist Wet grinding may have some of its own problems, but it is one of the best ways to reduce the amount of dust generated by grinding concrete. This process involves installing a wet cutting port for the abrasive tool to prevent the silica from being suspended in the air from the beginning, thereby greatly reducing the risk of its inhalation. Vacuum cleaner and HEPA filter If you decide to abandon wet grinding, you can still choose to use an industrial vacuum cleaner to suck up the dust before it gets into the air. These vacuum cleaners are powerful and can capture dust when it is formed, and once grinding is complete, it is also very useful for cleaning up excess dust on the job site. section. Good staff training The bottom line is that you or your employees need to know how to deal with dust to ensure the safety of everyone. Effective training and preparation is the key to ensuring that everyone stays healthy. The essence of the device. If you want to reduce the chance of harmful health effects, you still need to use a respirator.

how much will a concrete grinder remove? Concrete grinders use diamond or sometimes tungsten to grind the concrete layer. Most people use concrete grinders to remove very small amounts of concrete, or to remove glue and blemishes in concrete. You can expect that in most cases, using ordinary grinding wheels and abrasive tools, you will be able to take off about 1/16 inch of concrete. Let us look at an example. Suppose you want to remove 1/8 inch of concrete to make the concrete smooth, remove a little glue from the previous floor, and then prepare to use the new surface. You may only need to pass it once to peel the glue off the floor and take a small amount of concrete. This will provide a smoother surface for your next pass. Your next aisle will take off about 1/16 inch of concrete, and your third aisle will take off another 1/16 inch. This can almost bring you down to the level required for the entire floor. If you need to stand up or walk around a pillar, you may need to do more work. Some grinders will grind the edges so that you are flush with the wall. Other grinders will leave some lips behind, and you may need to use a smaller hand grinder for cleaning. Concrete grinding is generally considered a finishing or repair process. If the contractor wants to remove too much concrete, the concrete contractor usually recommends removing the concrete and re-pouring the concrete.

How to use an angle grinder to smooth the concrete? 1. Prepare the floor area with proper cleaning. You can simply wipe the floor with a vacuum cleaner, or if the floor is completely damaged, you may need to use a high-pressure cleaner to properly clean the surface. 2. The next step involves attaching the dust cover to the angle grinder. The dust cover should be firmly installed on the grinder by tightening the clamp on the range hood to lock the dust cover in place. 3. Next, you need to connect the vacuum nozzle to the vacuum adapter on the dust cover, and then connect it to the dry/wet vacuum inlet. 4. Now, with the power of the angle grinder still disconnected, you can install any grinding wheel that you plan to make the surface smooth on the angle grinder (I suggest you start with a diamond polishing pad). 5. After everything is connected and in place, you should now use the safety gear by wearing a mask, gloves, earplugs and knee pads. Start smoothing the surface by sanding the angle grinder around the room. 6. After smoothing the outer edge of the floor space, you can now operate the angle grinder in a circular motion inward, which will provide a higher degree of consistency. During the entire operation, you may have to constantly empty the waste collected by the wet/dry vacuum cleaner. grinding down concrete floor grinding machine polisher concrete mower concrete floor sander hire concrete grinding stone concrete floor polisher hire wet concrete polisher concrete edge grinder cut concrete with grinder grinding concrete smooth grinding concrete floor for epoxy

how to grind concrete？ Slow down the sanding speed Because the grinder has a variable speed function, it sometimes lifts and skips the surface during operation. If the machine runs too fast, it will reduce the construction efficiency. Although running with a higher speed setting speeds up the polishing of the floor, the result is often an uneven performance, leading to more rework and lower satisfaction. Increase concrete cushion If you find a lot of sand and machine-generated debris when polishing the concrete floor, the most likely situation is that the concrete base layer is too thin and the concrete base is ground. Large grit at the bottom of the concrete will wear expensive diamond grinders, and it is also very disadvantageous for vacuum hoses and filters. Therefore, it is necessary to increase the concrete floor cushion before polishing to increase the thickness of the floor. Use suitable lubricating oil When using a scraper tool on a sander or a cemented carbide tool on a ripper, you need to spray a mild lubricant on the tool. This process will help the tool to keep cool, and will reduce the amount of material accumulation on the tool. This process is very effective in protecting the sand box chassis on the ripper. When cleaning polished floors or coatings, try not to use cleaning compounds. Detergents are very popular, because dirt and dust are sealed in oil, and the solids remain dry, making cleaning easier, but this can impair the functionality of the sanding machine.

Ground grinding requires a long time of concentration, but many days of hard work may be ruined by a small mistake. If you want to polish the ground into a mirror, you need to pay attention to the following points: Repair the ground before construction to keep the ground level. When grinding the floor, clean the gravel in time to prevent the gravel from scratching the floor or damaging the blade. When using the dry grinding method, the water content of the ground should be measured, and it should be <20%, otherwise the resistance will be large and the resin film and the ground will be damaged. The beach curing agent needs to be evenly applied to the ground and moisturize for 30 minutes. When performing polishing work, first clean the polishing pad and remove the fine sandstone inside to prevent scratching the ground during polishing
