Portable versatility
October 13, 2008 By: Darren Constantino, North Coast Media Pit & QuarryWhen Kay and Kay Contracting in Kentucky decided to develop a new site for a limestone quarry in January 2008, owner Bill Robinson turned to Powerscreen Crushing & Screening, the Terex Pegson and Powerscreen distributor for Kentucky. He knew he could count on the company’s advice on portable crushing and screening equipment.
Paul McCaffrey of Powerscreen Crushing & Screening recommended a specific lineup of crushers and screens that would allow Kay and Kay to achieve its operational objectives and stay within budget. McCaffrey has experience in the industry and a machine service background in Ireland.
A major advantage of the Powerscreen and Terex Pegson machines, Robinson said, is that he can also utilize them in his contracting and road-building businesses and is not limited to a static or stationary system.
“I’m able to bring the machines to sites for my demolition crushing needs and then on to my highway projects, as well,” Robinson said. “With the fuel-costs these days, we need to be able to minimize our transport costs. With [these] Powerscreen and Terex Pegson machines, we are able to cut out much of our excess transportation.”
End product
Kay and Kay, road building and commercial contractors, were looking to produce 1/4-in. minus manufactured sand, #57, 1/2-in. x 1/4-in. (#8), and a 1-mm minus agg-lime as their core products for their asphalt and concrete business.
After reviewing the Kay and Kay quarry site in London, Ky., and measuring the limestone’s high silica density, McCaffrey suggested a crushing and screening circuit comprising the Terex Pegson XR400 26-in. x 44-in. tracked jaw crusher, Powerscreen H6203 20-ft. x5-ft. three-deck, triple-shaft horizontal screen, Terex Pegson 1300 Maxtrak cone crusher and two Powerscreen Chieftain 2100X incline mobile screens.
With a current output of 2,900 tons per day, Robinson and his quarry manager Lee Killion are able to achieve 80 percent of their most profitable specification products and 20 percent of a dense grade 2-in. minus for construction fill that the company uses on other projects.
Equipment specs
The Terex Pegson XR400 features a patented hydraulic release system, which protects toggle plates against tramp material. It also includes hydraulic-adjust for efficient jaw settings. The Powerscreen H6203 features a triple-shaft 20-ft. x 6-ft. horizontal screen box for higher amplitudes able to produce 544 tons per hour.
The Terex Pegson 1300 cone features the Automax All-in-Feed design, which allows for improved stone cubicity, and the Powerscreen Chieftain 2100X features a 20-ft. x5-ft. three-deck screen with oil-bath bearings and an adjustable screen-amplitude for improved stratification in finer applications.
Another factor in Kay and Kay’s decision was Powerscreen Crushing & Screening’s history and reputation in the marketplace and the company’s ability to service the machines if anything goes wrong.
“We need someone local that knows the machines and stocks parts and not just another trunk-slammer out here”, Robinson said. He cites his is good standing and trusting relationship with McCaffrey as being essential for his operations’ up-time and profitability.
