Choosing the right sandblasting sand
Sand blasting machine uses fine mineral media aka sandblasting sand, of which there is a great variety. Each type of sandblasting sand has different uses and attributes, some of which are common for shot media and shotblasting machine, but sandblasting sand has numerous uses depending on its attributes. Shot blasting is mostly used for hardening of metal sheets and removing of tough impurities, whereas sandblasting yields many different effects. The most common use of sandblasting sand is to remove contaminants or impurities from sensitive (soft) surfaces, such as bricks, wood and so on. Another common use is to alter soft surfaces, such as to carve signatures, cut or wear a surface out.
The most often used sandblasting sand is silica sand, but it is hazardrous to health due to lung illness or silicosis. Silica sand particles scatter on impact and remain in air, where they can enter lungs from and eventually cause a serious illness. That is why protective equipment is mandatory for workers operating sand blasting machine with sandblasting sand such as silica cand. The need has arisen for sandblasting sand that does not pose a health hazard.
An alternative sandblasting sand is slightly more expensive but safe garnet dust. There are other alternatives, such as artificial sandblasting sand, ground nuts, variety of mineral sand (with similar properties to garnet) and dry ice, which evaporates on impact and thus doesn’t present any health risk to workers. An alternative solution is enclosed sandblasting cabinet, where sandblasting sand remains trapped in a limited environment and does not circulate in environment. Sandblasting cabinet also recycles sandblasting sand easily, as none of it can escape.
Choose the right sandblasting sand not by the price, but quality and safety. Quality and no-hazard sandblasting sand will take you a long way as well as ensure high-quality products, whereas cheap sandblasting sand can cause premanent damage to both your products and workers.
Try our sandblasting machine and equipment
When we talk about sand blasting we normally think about removing color from different surface. But sand blasting can be use for many other things, but only if we have proper sand blasting machine and of course proper equipment.
Sandblasting machine can be mobile or stationary, but since we should all know what difference is let’s go to other classification. Normally we classify sandblasting machine in 2 categories, pressure blast system and pressure blast system withought dust.
The work and scisnce behind how it works is the same in both. Machine generates high pressure and then shoots abrasive to surface and therefore removes paitn and clean surface.
The difference between these two machines is size, dust adn equipemnt needed for it.
For normal sandblasting we just shoot sand which makes a lot of dust. Equipment needed for that is not that much different from shot blasting machine.
But if we talk about dustless sand blasting we need way bigge machine and more hoses. Also machine has recycling filter as part of that extra equipment and different nozzles.
The main difference here is that all the abrasive that is used it being vacuumed back and recycles so you can use abrasive again. But sadly you can only blast some of the surfaces and not all.
