"A very big part of our business comes from rush orders," Kobyluck says. "So we have to be able to quickly crunch a lot of stone through our system to keep up with sudden demands plus a generally increasing overall demand.

"We've dealt with Powerscreen of Connecticut since 1991 and have been very satisfied with their knowledge of quarrying operations and equipment, as well as superior parts and service backup, even on weekends. They do whatever it takes. Once when we had a problem, the dealer brought their service team to the quarry that Saturday morning and told them simply: 'Don't leave here until the machine is working.' Fortunately it only took a couple hours or so. But that kind of dealer commitment is crucial.

"Another crucial factor is the Automax design of the 1300 Maxtrak cone," Kobyluck emphasizes. "It has a closed side setting for easy adjustment while the machine is running. And fines can cake up and damage other makes of cone crushers, but not the Automax. Further, the 1300's cubicity is ideal. The crushed product is smoother and has a better finish without a lot of jagged edges; so it's much more 'workable' for making concrete. Before we got the 1300 Maxtrak, we were using a smaller stationary cone by another manufacturer that just wasn't getting the job done.

Specific materials produced at the Rattlesnake Quarry include #6 (3/4″, 3/8″ and 1/2″); #7 (1/2″); #67 (1″ blend: #6 and #7 combined); #4 (1½″); and #3 (6″ coming straight out of the jaw crusher). The 6″ product is conveyed first to the Powerscreen Warrior 1800 primary screen to scalp a 1″ minus base material. The 1″ plus overs are then sent to the Terex Pegson 1300 Maxtrak cone to make 1″ minus material that goes to the 20x6 Powerscren H2603-R triple-shaft, three-deck horizontal screen with the re-circulating feature.

Kobyluck has been operating the Premiertrak 1165 (26x44) since 2005; the Warrior 1800 since 2006; the 1300 Maxtrak and H6203-R since April 2008. Replacing the old 26x44 jaw and old, smaller cone in April 2008 has completed the current system that has doubled previous production and improved product quality so dramatically.
