Mining

Excavation Sites

• Large open-pit mines
• Quarries
• Underground operations

Coarse and Fine Ore Processing Plants

• Primary crushing and overland conveying
• Secondary and tertiary fine ore crushing, screening and conveying
• High Pressure Grinding (HPGR) and High Pressure Roll Crushing (HRC) and conveying
• Crushed ore storage bins
• Lime storage silos
• Assay labs for processing core samples
• Pressuring electrical control rooms

Controlling dust from mining processing equipment such as crushing, screen, and conveyor transfer points is a difficult challenge. Both the Mine Safety and Health Administration (MSHA) and the Environmental Protection Agency (EPA) are working with mining companies for the protection of people and environments by reducing dust emissions around mine sites. Both agencies have strict limits on the amount of dust that can be emitted; if emissions are too high, productions schedules may be curtailed and fines can be imposed. This is why proper design and selection of dust control equipment is such an important concern.

In addition to meeting regulatory requirements, reducing emissions protects personnel, the air quality of surrounding areas, and reduces wear and tear on production equipment. A proper dust collection system will allow allow for reliability in operations, and ease in 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 heavy-gauge construction and a modular design that optimizes field flexibility in harsh mining environments.

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.
• Special 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.

Below the following items display elements and functionality of mining dust collectors.

The Farr Gold Series has additional unique features and options not covered here, including provisions for future needs and expansions. Farr will help with finding solutions to specific problems that you are trying to solve.

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 not found in competitive cartridges, which 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 very high moisture applications, we have our Dura-Pleat filter, which shares a design with the HemiPleat, but uses a spun-bond polyester material for ensuring moisture will not degrade filter life.

Proper Sizing of the Farr Gold Series

Mining applications require a specific, maximum air-to-cloth ratio when sizing up the dust collector system for the intended operation. Camfil APC has professional personnel with many years of experience in the mining industry to review your project and propose a customized Farr Gold Series system.
