Dust Control in Mines

It's very challenging to control dust from mining processing equipment, such as crushing, screen, and conveyor transfer points. Both the Mine Safety and Health Administration (MSHA) and the Environmental Protection Agency (EPA) are working with mining companies to reduce dust emissions around mine sites to protect people and the environment. Both agencies have strict limits on dust emissions. If emissions are too high, production schedules may be curtailed and fines can be imposed. This is why proper design and selection of dust control equipment is an important concern.

In addition to meeting regulatory requirements, reducing emissions protects personnel, improves the air quality of surrounding areas, and reduces wear and tear on production equipment. A proper dust collection system offers reliable operations and ease of maintenance.

The Farr Gold Series industrial dust collector is uniquely suited to meet the requirements of the mining industry in the 2.5 micron and 10 micron size Particulate Matter (PM) ranges. It is extremely rugged with a heavy-gauge construction and a modular design that optimizes field flexibility in harsh mining environments.

What sets Camfil APC apart as the leader in high-efficiency filtration design is the Gold Cone cartridge filter. This filter combined with our unique collector design results in a solution that works well in a harsh mining environment.

Moisture Concerns

One of the main concerns with cartridge dust collectors is how well the pleated cartridge design will hold up against moisture. Will the moisture in the ore present plugging problems?

Not with the HemiPleat®. Take a look at the standard "dimple-pleat" separation method versus the Gold Cone® filter with HemiPleat pleating technology:

The key to the HemiPleat's superior performance is Camfil APC's exclusive, state-of-the-art pleating technology. Synthetic beads hold the pleats of the cartridge open with wide pleat spacing. In comparison, the pleats in competitive cartridges are packed too tightly to maximize media use, especially in mining applications. The wider spacing of the HemiPleat design improves cartridge release characteristics during pulse cleaning, greatly reducing the potential for plugging. For high moisture applications, we have our Dura-Pleat filter. This filter shares a design with the HemiPleat but uses a spun-bond polyester material to ensure moisture will not degrade filter life.

Farr Gold Series Industrial Dust Collector

FARR GOLD SERIES INDUSTRIAL DUST COLLECTOR

The Farr Gold Series The Farr Gold Series dust collector performs well in applications where dry materials are batch mixed, conveyed and processes. The Farr Gold Series offers high performance, a modular design, ease of service, and an optional bag-in, bag-out filter change out. Constructed from heavy-duty carbon steel to meet the demands of your application, the Farr Gold Series has unparalleled strength and life compared to the competition. Coupled with Gold Cone™ vertical cartridge technology, the Farr Gold Series offers superior pulsing of high-loading dust while simultaneously utilizing the smallest floor space of any dust collector available today.

Benefits of the Farr Gold Series for Mining
  • High-efficiency filters stop 99.99% at 0.5µ of the dust.
  • Unique high-entry inlet design allows large particles to drop out, eliminating can velocity and giving longer filter life.
  • Specially treated filter media repels the fine particle for lower pressure drop and long filter life.
  • Exceeds the lowest emissions requirements for compliance stack testing with results of less than 0.001 gr/dscf on hard rock crushing screening and conveying operations.
