Although the design and selection of a dust collection system is best left to a professional designer or engineer, a basic knowledge of how these systems are put together will help ensure that shop owners and managers get one that is properly suited to the needs of their company.
There are many factors to consider when determining the correct size and configuration of a dust collection system. How many dust-producing machines will be on the system? What is the dust collection pickup size on each machine? Are there any plant layout and dust collector location issues? What type and weight of material will be collected? How much waste is anticipated? Is there a preferred method of material disposal, such as drums, rotary airlock or truck disposal? Which type should be considered, shaker-style or continuous cleaning?
When designing the dust collection system, the first step is to produce a list of dust-producing equipment. From the list of machines, the total volume of air required for the system can be calculated.
Next, determine the location of the dust collector. Bear in mind accessibility for both the initial installation, as well as for waste disposal vehicles, if applicable. Also consider whether the dust collector will be located inside or outside the facility.
Always check with the local authorities, such as the Fire Marshal’s Office or the Ministry of Labour, to determine the type of dust collector allowed in that jurisdiction before making a purchasing decision.
Using a scaled drawing, lay out the ducting so that each piece of machinery is connected to the dust collector through branch lines connected to the main duct.
This layout is then used to determine the static pressure of the total system. The next step is to determine the filter area required for the system.
We now have the basic requirements to determine the size of the dust collector. This data, along with the requirements for waste storage/ disposal and accessories required by provincial and national codes, will determine the configuration and size of the dust collector.
Some initial work, using the above information, will make quote comparisons for dust collection systems a little easier to break down and should allow plant owners and managers to make a more informed decision as to the suitability of the equipment for their particular operation.
