Gas Cleaning Plants

Gas cleaning devices used within the industrial minerals mining industry are used to clean ventilation airstreams of harmful particulate matter. The choice of air cleaner for any particular installation will depend on the following:

• dust concentrations and dust characteristics
• particle size
• the efficiency of particulate removal required
• airstream temperature
• airstream moisture content
• methods of disposal

Distinguishing dust characteristics that affect the collection process include abrasive, explosive, sticky or tacky, and light or fluffy. The shape of the dust particle is also important because it factors into whether the particles are agglomerating (irregular) or non–agglomerating (spherical), which is important when using a filter cloth. For collection purposes, agglomerating particles are ideal as they allow dust cakes to build up easily on the filter cloth, allowing for more efficient collection at the dust collector. However, agglomerating particles may have a tendency to not release from the filter cloth very easily.
