Filtration concerns orbit every stage of a productive mining operation. The filtering media is in the air, defusing the dusty black dust released by extracted fossil fuels. Conversely, production cycles use special sieves to separate valuable geological commodities from coarse earthen matter. Even fluid power systems use filters as barriers, purifying devices that keep hydraulic oil clean. Here’s a closer look at filtration in mining.


Productivity hinges on drive system mechanics, the lubricated parts that power kilometre long conveyor belts. Meanwhile, vibratory motors push multi-level screening decks back and forth in a synchronous pattern, all the better to efficiently part the ore-laden material from a mass of grinding rock. Filters and powered dryers come to the rescue in this scenario by supporting sealed bearing housings. The hydraulic fluid works in concert with electrical subsystems to fluently maintain mechanical motion, and it’s the filters that intelligently enable this process. Specially sized apertures in the filters allow the oil to pass but stop parts-damaging particulate matter.


As the filters are installed and maintained in the above mechanical systems, we stand back for a moment to consider the advantageous nature of this system asset. The sieving component is a protective device, a piece of apparatus that extends machine lifespan by keeping the mechanical muscle utterly devoid of contaminants. Similarly, fuel filters protect the drive chain, thus ensuring the supplied mechanical momentum is always reliably at the beck and call of the screening and crushing machinery.


Air reclamation is another task for a mining filter. The deep-level mechanism eliminates carbon dioxide and dehumidifies the clammy air, so mining personnel can breathe freshly-scrubbed oxygen. Next, the water down in the lower reaches of the mine is dirty. It can be pumped up to the surface and cleaned, of course, but the better option is to clean this life-giving resource below ground. A cost-effective solution filters wastewater and conditions it for use in a dewatering stage. Of even more importance, the wastewater is continually cleaned so that it can’t enter the local water table without polluting the environment.

A proper filtration strategy covers several different mediums, including water, air reclamation, and fluid power. The proper filter must be matched with each of these applications if the mining facility is to satisfy national and international safety guidelines, rules that are as ecologically sound as they are productivity-oriented.
