Iron Mountain Trap Rock currently drills and shoots a 135-foot rock face. The material is then loaded into 50-ton haul trucks and dumped into a Primary Jaw Crusher that crushes it down to an 8” minus. It is then conveyed approximately 2,000 feet to the Secondary Plant where it is processed through three cone crushers and screened into the finished product. A modern rail spur at Iron Mountain Trap Rock allows loading of 80-car unit trains.
