and is packed tight around ties to anchor and cushion them The irregularly shaped stone tends to lock together forming a stable foundation Many tons of ballast material is utilized for every mile of new track and the rock is regularly replenished The first of the ballast material mined at the new Trap Rock and Granite Quarries property will be utilized on site because the heart of the quarrys modern loadout operation is an oblong railroad track loop encircling 70 acres The initially quarried stone will be turned into ballast for the quarrys rail system which ultimately will comprise some three miles of side by side tracks and feeder tracks for the Union Pacific main line A contractor is moving earth to carve out the private railway Missouri red granite is commonly used for decorative veneer and monuments but its also a superior aggregate for construction and landscaping roadbed but only two thirds of the loop will be constructed in a first phase of operation A rocky outcrop where the far side of the tracks eventually will be laid has to be quarried to get it down to grade Some 2 million tons of rock will be carved away in that leveling operation In addition a partial double loop of track will be built in the first phase of construction When complete 35 cars at a time will roll across those rails for loading with aggregate before being shunted back to the main track After the obstructing rock is removed and the full loop is completed the double track will be able to accommodate two 110 unit trains The completed railroad loop will become the focal point of quarrying operations for the remaining 1000 acres in the tract Very little overburden will have to be removed before rock in the quarry can be accessed and broken up using standard drill and blast mining methodology Fourteen yard wheel loaders will scoop up the loosened material and 75 to 100 ton off road trucks will haul it away and dump it near the outer edge of the rail loop There initial crushing operations will ensue with the reduced rock eventually conveyed over the tracks to a point inside the loop for additional crushing screening and washing operations Finally stockpiled and washed rock will be moved via drawdown tunnels to an overhead bin for dumping into hopper railroad cars The loading system will incorporate track scales for weighing cars and weighted dumps of material to ensure trains are uniformly loaded The automated system is designed to load out anywhere from 2000 to 5000 tph A look ahead Company engineers and management are still designing the new quarrys crushing and screening operations Perrey says they will be built around a 1200 tph jaw crusher with second TRANSPORTATION WABASH MPI Proppant Crush Test Press s OMPATIBLE WITH 3 s OR USE WITH FRAC SAND RESIN COATED SAND AND CERAMIC PROPPANT This Genesis Series press meets the critical demands of ISO 13503 2 2006 with unsurpassed cycle repeatability The proportional hydraulic system is capable of applying a constant rate of 38 MPa min 2000 PSI min from 2 ton to 28 ton clamp force within a 25 deviation The operator interface allows easy setup of press control parameters and includes ample recipe storage Visit our website or contact us for more information ISO 9001 2008 Certified www wabashmpi com Tel 260 563 1184 wabashmpi@ corpemail com 28 PIT QUARRY June 2014 www pitandquarry com
