Grinder Dust Collector

About Grinder Dust Collector

When you are grinding concrete, the ground dust is bound to fly into the air, which can be harmful when one inhales it in. A grind dust collector, more commonly known as the dust shroud, is a piece of dust collection equipment that attaches diamond-tipped angle grinder to a vacuum which sucks in the harmful dusts created from these grinding operations.

As the name implies, grinder dust collectors are capable of removing most of the dust created from grinding and disposing of them safely. Although dust collectors are mainly used in concrete grinding, they are also commonly used in woodworking operations where sawdust and particles are released into the air, all of which can damage human lungs and coat equipment.


Why is a Grinder Dust Collector Needed?

Of course, you can always choose not to use a dust collector or dust shroud with your angle grinder, but you will end up spending a lot of time, effort and resources cleaning up the dust. Although these concrete dust and wood sawdust do not pose immediate danger, they can cause lifetime conditions, such as silicosis (a condition that inflames and damages the lungs), if you continue to breathe in these particles for a prolonged period of time.

Even though these harmful particles can be reduced using other method, such as using wet cutting rather than dry cutting. However, as wet grinding typically takes longer time than drying grinding, you may not have the money and time to alter the existing grinding process, let along tweaking the deployment of manpower.

Last but not least, concrete dust can damage or clog your grinding material and the relate equipment over time. This means that you may be looking at a much higher overhead cost from repairing, maintaining or even replacing these equipment. So why not opt for a grinder dust collector to avoid these indirect cost all at once?


Factors to Consider When Buying a Grind Dust Collector

With the above said, it is definitely not wise to save a little bit of money (from not using a dust shroud) at the expense of health. Although it is human nature to neglect the unseen, these dispersed, invisible particles can be hazardous to your health.

Now making the decision to obtain a dust collector is one thing but knowing what to expect when setting forth to buy one is another. We’ve listed some selection factors that you should consider when buying a grind dust collect as follows:

● Filter Size:
Filtration and dust collection technology has undergone drastic changes over the last few decades. In the early days, a dust collecting machine was nothing more than a single-stage collector coupled with a 30-macro bag. These bags were so ineffective that they almost did more harms than goods. The filter capability was poor; smaller dust particles were often not filtered properly (and they are often the more harmful ones!). 

As a matter of fact, particles smaller than 10 microns are typically the most hazardous as they are small enough to get into your lungs. And human body is not equipped with the ability to extract these tiny particles. Therefore, you need to make sure that your product is able to filter down particles at least 2.5 microns. If necessary, you can even find dust collectors that can filter particles as small as 0.3 microns.

● Suction Power:
Suction power is directly associated with an equipment’s dust collection capability. A grinder dust collector with subpar suction power is without a doubt undesirable. You might as well not buy one at all. Suction is measured by CFM. How much suctions power you need is largely depended on your lines of work and the tools you in the related operations.

The rule of thumb is that the resistance of the suction increases and you add to the length of the pipe. So, you will need to calculate the amount of static-pressure loss that takes place between the grind dust collect and where your tools are located. On a side note, your manufacturers and vendors should provide performance curves for your reference.

● Single Stage or Two Stage:
Single stage systems are typically cheaper than two stage systems. Although functionality does not always justify the cost, the statement upholds in terms of dust collection equipment. A two-stage grinder dust collect can draw air into the separator that filters the larger parts out. From there, the filter is approached by the smaller pieces. Imagine if the filtration only consists of one stage, big particles are likely to clog the single filter, preventing the rest of the smaller articles from entering through the filter. This is why a two stage grinder dust collector will always be the preferred option.
