Foam System Vs Dust Extraction System
Dust extraction and fogging systems are trying to treat dust that is already airborne.
Once dust is airborne it is very difficult to control.
Dust extraction systems have a very high capital cost followed by higher running and maintenance costs.
Foam systems require a fraction of the amount of energy needed to run an extraction system.
The maintenance requirement of dust extraction systems are substantial and as a result they often fall into disrepair.
The removal of the extracted dust is another consideration and activity that needs to be managed to allow the dust extraction system to function.
Dust extraction points are needed at every dust creation point and this is often neither practical nor cost effective.
Foam System Vs Fogging System
Fogging systems are designed to suppress dust that is already airborne - which is often too late.
Once the airborne dust has been wetted there is no control as to where this wetted dust will settle. It will often fall onto plant, machinery, building, walkways, ledges and the surrounding area.
This creates a further housekeeping task as the dust can potentially become a hazard.
Limited effectiveness.
Foam System Vs Water Spray System
Up to 50 times as much water is required to have the same effect as foam.
Only effective when moisture content is not a concern.
High moisture content increases the likelihood of blinding screens or blocking chutes.
Access to high volumes of water is required.
Benefits Of Foam Dust Suppression Systems
Prevents the dust from getting airborne.
Foam systems use up to 70% less moisture than water spray systems whilst achieving up to 90% reduction in fugitive dust emissions.
Less moisture in the material reduces plant wear.
Less moisture in the material reduces the chance of the blinding during the screening process which is a significant problem with conventional water spray systems.
Less moisture can offer significant savings in downstream processes, such as transportation costs, or drying costs, in asphalt production for example.
Foam systems expand the physical properties of the water allowing for greater coverage with reduced water consumption. Ideal for situations where water is in short supply.
Wetted dust particles will then continue their entire journey through subsequent crushing and screening process to the final storage bins without ever getting airborne.
Reduces the amount of housekeeping required.
