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 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.

Camfil APC's Exclusive HemiPleat Design
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.

Which type of dust collection system will save money over time, a traditional baghouse or cartridge-style collector?
- Modular construction – easy to build and assemble in limitless sizes and configurations
- Tested to meet NFPA & ATEX standards
- Available with numerous explosion protection options
- Exceeds OSHA mandates for factory air quality
- Less pulsing of filter cartridges is necessary, so the filters last longer and require less changeouts
- Smaller footprints are possible because each unit handles more airflow
- Ships in as few pieces as possible for fast delivery
- Easy installation, operation and maintenance
- Built on 20 years of reliable field dust collection performance Gold Cone® X-Flo filter cartridge contains 375 square feet of media, offering the industry’s highest air-to-cloth ratio
- Can be equipped with eXtreme filter media offerings that are rated MERV 15 per ASHRAE 52.2:2007.
- 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.
