Wet blasting x dry blasting
Updated: Dec 3, 2021
There are several differences between dry blasting and wet blasting. Therefore, we listed the main advantages and particularities of each one so that you can see what makes the most sense for your company.
In the dry blasting machine, the steel shot can be reused several times, and that's why it is extremely ecological. This is one of the main factors that make that this machine continues to be a more economic, productive, and ecological option.
In the North American market, it is customary to use dry blasting whenever possible. When there are field applications, with the possibility of containing the blasted area (enveloping), equipment associated with mobile abrasive purifiers (ARM) is used. Garnet is the most popular abrasive in these applications.
In some cases, the possibility of recovering and reusing the abrasive can be time-consuming and costly, which ends up not paying off. In this scenario, it's recommended the utilization of the water blasting machines that demand a lot less preparation for the service.
In resume, the water blasting can be done more simply, as it is not necessary to "envelop" the site. This equipment does not generate dust and does not affect installations nearly to the working area.
When selecting the wet blasting, the important thing is to know that the more water the machine uses, the less productive it will be. The water works as a friction inhibitor and in high volumes, it reduces the rugosity.
There are several wet blasting systems. Those that manage to operate with a lower volume of water are those that work with dry abrasive and inject water right after the abrasive metering valve exits, dampening the abrasive just enough not to generate dust - a system used by CMV®.
CMV® wet blasting equipment has the lowest water consumption per blasted f² in the market. For this reason, they are the most efficient and productive. Machines with this operating system can also be used to wash surfaces (using only air and water), to dry (using air) and, of course, to perform wet blasting, combining air, abrasive, and water.
Wet blasting can also be applied when blasting thin sheets, such as the body of a car. In this case, the advantage of wet blasting is that it is properly regulated does not deform the blasted part, which is common in dry blasting.
