Dust collecting systems consist of several components, all of which work together to reduce workplace contamination caused by dust particles. These machines are commonly found in manufacturing facilities, workshops, and plants.
Most fabrication industries involve processes that release particles such as dust or fine chemicals into the air, which can be harmful to the well-being of the equipment as well as the workers who manage them. Thankfully, dust collecting systems are built to help minimize this risk.
These systems operate by separating harmful particles from the air, and sometimes releasing the clean air back into the workplace. Metalworking, woodworking, scrap metal, recycling, and toxic media are just a few of many applications for which dust collecting systems are used. Dust collecting systems are used by numerous industries, including cement fabrication, metal fabrication, mining, furniture, recycling and agriculture.
Dust collecting systems do have one disadvantage—they take up a lot of space and, once designed, cannot be easily reconfigured. However, their elaborate setups allow for more effective particle reduction in the air, thus increasing the longevity of equipment and improving the working conditions for employees. Read More…
Most dust collecting systems feature ducts, suction hoods, and capture arms that hang over areas where dust is formed, assisting in the collection process. The air is then drawn through a central suction unit which transports the air to one of the dust collectors within the system. Dust collecting systems may involve multiple types of collectors, like baghouses, baffle chambers, and cyclone dust collectors.
Baghouses are the most common and most efficient type of dust collector. The contaminated air is drawn through a duct. Within the machine, a fan creates a vacuum, and it forces the air through fabric filters located in a bag.
The fabric filters catch the particles, and clean air exits the machine’s outlet while dust particles settle to the bottom of the machine’s chamber. A different type of baghouse, known as a jet dust collector, utilizes jets of air to reduce dirt buildup in the fabric filters.
Cyclone separators fall under the type of dust collector known as an inertial separator. Inertial separators separate dust particles from the air by way of centrifugal force within a hopper-shaped chamber.
Since particles are heavier than air, they are forced against the wall of the chamber and then settle to the bottom where they are collected.
There are other systems that use portable collectors for efficient localized dust collection, and self-contained collectors such as downdraft tables that are ideal for independent work areas.
Dust collecting systems may come in a variety of configurations, but regardless of the type, they are a key component in reducing chemicals and other particles in the air, and ensuring that equipment and workers alike are safe.
