The Essential Role of Dust Collectors in Mining and Quarry Operations | Aerodyne

Posted by Tom Hobson on Oct 31, 2024 1:45:00 PM

The mining and quarry industries are known for their inherent risks and hazards. For the workers and companies in these fields, safety is not just a priority—it’s a lifeline. Yet, these industries continue to face critical challenges that demand attention, including fire hazards, dangerous dust, and the need to protect both employees and nearby communities. Thankfully, modern dust collection systems are transforming the way we manage these risks, offering safety benefits, environmental protections, and even financial advantages.

The Risks of Inadequate Ventilation and Dust Exposure

One of the most dangerous threats in mines and quarries is the potential for fires and explosions. In enclosed mining spaces, inadequate ventilation can lead to a buildup of flammable gases, creating an environment where even a small spark could trigger a devastating blast. Proper ventilation, combined with reliable dust collection, is essential to controlling these risks.

But the danger doesn’t stop at fires and explosions. Workers are often exposed to dust-laden air that can be hazardous to their health. Inhaling fine dust particles over time can lead to serious respiratory issues, including silicosis and other lung diseases. Silica dust, a common byproduct of mining and quarrying, is particularly harmful and requires careful control to prevent health risks to those on-site. Improving air quality is not only a matter of regulatory compliance; it’s also a key component in fostering a safer, healthier work environment.

The Role of Dust Collectors: A Multi-faceted Solution

Dust collectors serve as an essential solution to many of the challenges faced in mining and quarry operations. These systems work by capturing and removing dust from the air, helping to create a safer and cleaner environment. By allowing dust-free air to be vented outside and drawing fresh air into the mine, dust collectors significantly improve air quality and mitigate the risks associated with dust exposure. This process reduces the likelihood of respiratory issues for workers and helps maintain visibility on-site, which further contributes to safety.

In above-ground quarries, dust collectors are equally important. Here, they control “nuisance dust” that can affect neighboring communities and ecosystems. Dust carried off-site can pollute the air, soil, and water, affecting local environments and potentially leading to health complaints from nearby residents. By containing dust at its source, companies can be better neighbors, fulfilling their corporate responsibility to protect both the workforce and the surrounding areas.

Economic Benefits: Recovering Valuable Materials

Beyond safety and environmental protection, dust collectors also offer economic benefits by capturing valuable materials that would otherwise be lost. Many types of dust collected in mining and quarrying contain recoverable raw materials that can be repurposed or sold. This process not only reduces waste but can also generate revenue, making dust collection systems a valuable investment for mining and quarry operations.

Airflow Through a Dust Collection System | Aerodyne

Posted by Tom Hobson on Sep 25, 2024 10:15:00 AM

When you are dealing with dust collection system, the most important component is having the correct airflow going through your system so that the dust collection is properly done. While this initially appears to be simple it is the most complex part of a dust collection system. To put it simply, every component from the pickup hoods to the exhaust stack affect the airflow going through the system. And any changes, whether deliberate (ex. changing filters) or accidental (filters plugging) the airflow in the system will be affected. The following explains the different components in the dust collection system and how they affect the airflow.

Pickup Points/ Hoods

Most dust collection system have pickup points/hoods that are used to collect the dust by pulling the air around the location into the dust collection system. The amount of air and the profile of the airflow is based on the hood design. Some hoods are located close to the dust source while other hoods are used to pick up dust across a large area. Using the correct hood is very important when you are designing the dust collector. If you are using a hood designed for pinpoint collection but need to collect over a wide area you will not get the dust collection you are looking for. If you use a wide area hood for pinpoint collection you will be collecting more airflow that is required, thereby increasing the size of you dust collection system.

Ductwork

Now that we have captured the dust in our hoods, we must transport the dust from the hoods to the dust collector. Sometimes you located the dust collector right next to the area you are collecting the dust and sometimes it is located all the way on the other side of the facility. Some dust collectors are dedicated to a single area or process while others handle multiple areas (hoods). All of this requires ductwork to transport the air from one place to another.

Dust Collectors

There are many different types of dust collectors that you can use in the system. Each of them have certain strengths and weaknesses. The most common are baghouses, cartridge collectors and wet scrubbers.

Baghouses and cartridge collectors use a filter media that builds up dust and prevents the dust from passing. The filters will be periodically cleaned (by shaking or with compressed air). Over time the dust layer will increase, causing the pressure drop across the filters to increase.

There are multiple types of wet scrubbers used for dust collection. The most common are venturi scrubbers and what can be described as cloud chambers. Cloud chambers use high pressure nozzles to create very small particles to make contact with the dust. While venturi scrubbers force the airflow and water through a small diameter section, forcing the water and dust to contact. Afterward both units have mist eliminators and/or packed towers to collect the water droplet.

Auxiliary Equipment and Accessories

The dust collection system might have auxiliary equipment such as pre-filters, HEPA filters, isolation valves, manifolds and control dampers which could affect the airflow in the system. They all could have pressure drops associated with them, which would need to be added to the system total static pressure for the proper airflow to be achieved by the system.

Exhaust Fan

The exhaust fan is usually the motive power behind the dust collection system. And usually the exhaust fan is a centrifugal blower. One of the characteristics of the centrifugal blower is that the airflow produced by the fan is directly tied to the static pressure produced by the fan at a specific speed. Each centrifugal blower has a performance curve which shows what the airflow and static pressure will be.

The main thing to remember is that if for some reason the pressure drop in the system increases, the airflow through the system will decrease according to the fan performance curve. Often times it is a good idea to install a variable frequency drive (VFD) on the fan so that you can adjust the speed of the fan allotting for changes in filter conditions and other process upsets.

So, to summarize, the dust collection system is sized and designed based on the total airflow going through it. Each of the components has an effect on the whole system, which often times are cumulative. Any modification of the system could affect every other piece of equipment, thereby affecting the total effectiveness of the system. As described above, the dust collection at the pickup points are entirely dependent on the airflow going through them. Any upset, modification, maintenance issue, etc. could affect that airflow, thereby causing the dust collector system not to provide the performance it was designed to do. Therefore, constant monitoring of the airflow in the system is the best way to monitor the dust collection system.

Extending Filter Lifespan with Cyclone Pre-Filters | Aerodyne

Posted by Tom Hobson on Oct 31, 2023 1:30:00 PM

Baghouses and Cartridge collectors are very good at removing dust from their air. However, when the dust concentration is high, or the dust is abrasive, wet, sticky or fibrous, the baghouse filters can have issues.  

  • High concentration will plug of filters quickly.
  • Abrasive dust will cause holes to develop in the filters.
  • Wet and sticky dust will plug up the filter and/or cause filter failure.
  • Fibrous dust will not easily fall to the hopper causing filters to plug.

Installation of a cyclone pre-filter is an ideal way of extending filter life.  The cyclone uses centrifugal forces to capture the dust and remove it from the airstream.  Often times the cyclone will remove 80-90% of the dust before a baghouse or cartridge collector.  This allows the filters to concentrate on the smaller dust that makes it past the cyclone.

And if you have a pulse-on-demand controller for your baghouse, you will further extend the filter life, as the filters will only be cleaned when required.

What is a cyclone dust collector?

Cyclone dust collectors are dust collectors that use centrifugal motion to remove dust from an airstream. They don’t have any moving parts and don’t use filters for dust removal. Most cyclones are vertical in design, even though Aerodyne Environmental has compact horizontal cyclone designs. They are often used as pre-filters to increase baghouse, cartridge collector and wet scrubber system efficiencies.

Cyclone pre-filters are cyclones installed before a baghouse or cartridge collector to increase the removal efficiency of the system.  They extend filter life and lower utility usages. The cyclone pre-filter is often used on those applications that have “Tough” dust.  “Tough” dust would be dust that is abrasive, hygroscopic, fibrous and/or wet. Often times this dust will cause operational issues with baghouse and cartridge collectors.

Why install a cyclone pre-filter?

Cyclone pre-filters are installed to optimize a dust collection system. This could mean increasing the removal efficiency of an existing dust collection system. It could be to extend filter life by decreasing the dust loading the filters are seeing, thereby decreasing the cleaning required. 

Additionally, cyclone pre-filters will lower compressed air/plant air usage by increasing the intervals between cleaning when a pulse-on-demand control system is used with it. And in those special applications, the Aerodyne SplitStream cyclone can add hot or cold air into the dirty airstream, thereby treating the air while collecting dust.

Signs You Need a Pre-Filter

The following are some signs that your dust collector isn’t operating up to par and you should look at installing a cyclone pre-filters.

  1. There is a high pressure drop across your filters. This is caused by the dust building up on the filters and not being cleaned off fast enough.  The high pressure drop causes the fan to pull less air to compensate, thereby letting more dust out on to the shop floor.
  2. Filters are being replaces too fast! The most common filter failures are by developing holes or plugging up.  Both failures are tied to high dust loadings.
  3. Valuable product or raw material is being disposed in the dust collector waste due to contamination. As stated above, filters build up dust layers to provide the removal efficiency. Those filters will retain the material over time. If the material is valuable, this can be a lot of money that is going to waste. Pre-filters will allow the material to be collected and used in the process or product before it can be contaminated in the filters.
  4. Do you have a high cost of water treatment and disposal of the scrubber blowdown? When wet scrubbers capture particulate, slurry is formed. This slurry will then have to be disposed. It will often be sent to a water treatment plant. The water treatment plant might be dedicated to the facility or municipal. Either way, additional costs are added to treat the slurry before it is disposed of or reused. A pre-filter removes a portion of the material before it is put into slurry, thereby saving costs on waste-water treatment.
  5. Similar to above, since wet scrubbers form slurries, any valuable material collected in the wet scrubber will be in that slurry. So, unless the desired state of the material is within the slurry, it will have to be processed to make it useful. This means additional steps (and expense) are required to recycle the material. A cyclone pre-filter removes the material dry, before it is in slurry, thereby saving costs.

So, before you decide to purchase a new dust collector, look into the benefits of installing a cyclone pre-filter.  You just might save yourself money!
