Dust collection is important regardless of the industry, and abrasive blasting is also a specific application in industrial production. Proper collection of dust from the blasting machine ensures the health and safety of personnel and efficient operation.
Below we'll dive into the specifics of blasting, how to use it, and how to remove this type of dust from the air.
What is sandblasting?
Sandblasting is the process of using compressed air or water to forcibly remove coatings, corrosion, and contaminants from the surface of an object.
Common types of blasting include:
Steel shots. Steel grit.
Alumina. Cullet.
No matter which application you use abrasive blasting for, dust will inevitably be generated. This lingering dust is not only harmful to employees, but also has an impact on production.
Sandblasting is commonly used to smooth rough surfaces, steel surfaces, remove surface contaminants such as paint, rust, or residues, forcefully clean surfaces, and even finish surfaces.
What are the dangers of sandblasting?
Since this particular type of blasting produces dust particles at a higher speed and pressure, a number of hazards can occur if not removed correctly. These hazards include:
Exposure to silica, cinder, and garnet can cause lung damage, inflammation, and scarring.
Fire hazards. ** Possibilities.
Diesel. Inhalation of toxic substances such as arsenic, beryllium, cadmium, etc.
In addition to the dust generated, the blasting noise is also very loud. It can cause hearing loss among workers. Workers working in noisy environments are advised to wear ear protection equipment.
There are a variety of ways to protect employees from airborne particulate matter and other hazards of sandblasting. In addition to providing appropriate PPE, it is important to consider installing baghouse equipment.
After installation, it is often found beneficial to install a baghouse to treat the air and collect dust.
Which dust collectors are suitable for sandblasting?
Pulse baghouses, cartridge collectors, cyclones, and gravity collectors are all ideal for use in the abrasive blasting industry. People commonly use DMC-36, DMC-64, DMC-80, DMC-96, DMC-120 and other small and medium-sized bag filters.
The dust source generated by the blasting enters through the air inlet at the bottom of the baghouse for efficient dust collection. When the pulse is sprayed, the dust is removed from the dust removal bag, and the collected dust falls and enters the ash hopper and is discharged by the ash discharge valve.
