Case Study: Nuisance Limestone Dust Cleaned Up for Employees

Got quarry dust? Then read on. Indiana Limestone Co., Inc. (ILCI) of Bedford, IN, needed to find a way to clean up massive amounts of dust generated in its limestone cutter's bay. Though limestone dust is completely non-toxic - being classified by OSHA as a nuisance dust - the word "nuisance" describes it well. The fine powdery material hinders visibility in the work area, permeates sensitive tools and machinery, and creates continual cleaning headaches. To solve the problem, the company invested in a high efficiency cartridge dust collection system.

"We wanted to solve these problems and create a more comfortable and pleasant environment for the 17 to 25 employees who typically work in this area," said ILCI General Manager George James. Continue reading this limestone dust collection case study...

Dust Collectors for Mining

Controlling dust from mining equipment at excavation sites, mill transfer points and similar locations is a difficult challenge. The EPA has strict limits on annual emission amounts. If emissions are too high, production schedules may be curtailed. That's why proper selection of dust collection equipment (including pleated baghouses) is such an important concern. Minimizing emissions allows production of more product.

Rock crushing, coal mining dust processing, and bin venting of quarry storage are mining applications. Some are really tough on dust collection equipment and call for custom components. Stack test results of less than .0005 grains per cubic foot of emissions can be achieved with the right configuration and filter media. One of the main concerns with pleated filter media is how well they hold up against moisture. Read more at Dust Collectors for Mining...
