When opportunity came knocking on Charlton (Chuck) Dygert’s doorstep, he was ready to take action.

The opportunity was to purchase a quarry in the booming gas well area in the northern Pennsylvania town of Millerton. Dygert, who had been working in the southern tier of New York and northern Pennsylvania for Dalrymple Contracting in a wide variety of roles for 14 years, knew the time was right to strike out on his own.

TMT Gravel, named after Dygert’s three children — Tyler, Morgan and (future CEO) Troy — was started in June 2010.

Dygert had a clear vision when he opened his new quarry — big and bad. The ability to put large volumes of material on the ground quickly was key to driving his cost-per-ton down as low as possible, he said. Having read about the new Powerscreen XH500 impact crusher, he contacted sales representative Jason McKinney of Emerald Equipment Systems for further information.

The XH500, an updated version of the Pegson 1412 impactor, is a tracked impactor featuring a 54 in. (137 cm) wide four bar impact chamber. Two new features on the XH500 in particular appealed to Dygert’s vision — the pre screen and under pan feeder.

The integral pre screen in the feeder allows TMT to screen out the fines before they go into the impact chamber, increasing the overall machine production and dramatically reducing wear. The under crusher pan feeder protects the product belt preventing ripping belts and down time.

Another key factor in Dygert’s decision was the ability of the XH500 to be used as a primary crusher taking the large feed directly from the face and yet still be able to be used to make a variety of products from R3 (6 in. minus) to 2A modified.

With average production of 600 to 700 tons (544 to 635 t) per hour, a high capacity screening plant and stockpiling conveyors were required. A Chieftain 2100 two deck 5 x 20 and two Telestack tracked conveyors fitted TMT’s requirements perfectly.

Having all four pieces of equipment on tracks allows TMT to move the equipment out, blast and be back crushing within an hour, according to the company.

Telestack track conveyors are heavy-duty self-contained units. TMT added the TC421 and TC621 models to its crushing and screening setup. The Telestack conveyors are engineered to be used after crushers and have heavy-duty belts, an impact bed under the feed end, a lined feed boot and the ability to independently raise the feed end.

Dygert’s past experiences with Pegson crushers and Emerald Equipment Systems parts and service while at Dalyrimple made the decision to do business a simple one, he said, adding that Jason McKinney and Emerald Equipment have been good to work with through the process. CEG
