Fabricator Case Study: Containing Limestone Dust

Camfil Farr APC worked closely with Air/Pro to customize dust collectors as needed to fit Indiana LImestone Co., Inc.'s unique requirements.

Indiana Limestone Co., Inc. (lLCI) of Bedford, IN, needed to find a way to clean up the massive amounts of dust generated in its limestone cutters' 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 its 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. "These artisans are carrying on a tradition of hand craftsmanship that has placed the company in the forefront of dimensional stone fabrication for more than 66 years." The company has handled some of the most prestigious construction projects in the country, induding the Empire State Building, the National Archives Building and the Willard Hotel, among others.

Indiana Limestone Co., Inc. (lLCl) of Bedford, IN, was in search of a way to clean up the massive amounts of dust generated in its Limestone cutters' bay. The fine powdery material produced by the material was hindering visibility in the work area, permeating sensitive tools and machinery, and creating continual cleaning headaches. To solve its problem, the company invested in a high-efficiency cartridge dust collection system.

James explained that ILCI, which produces approximately 1 million cubic feet of merchantable quarry volume annually, had tried other methods in the past to rid the factory of dust, but they were unsuccessful. "After buying and using dust collectors that failed to clear the air, and carefully researching other options, we found a solution using a high-efficiency cartridge collection system designed by Air/Pro Inc. and manufactured by Farr Air Pollution Control (APC)," he said.
