The RSMM1500-D10 Rock Miner is Rocksaw’s first production rock-mining machine, designed for a variety of applications in the rock mining, road construction, and concrete recycling industries. The Rock Miner weighs 200 tons, is powered by a 1,500-horsepower Caterpillar diesel engine, and has a production capacity of 500 to 750 tons per hour, depending on the material being excavated. The machine’s standard cutting arrangement produces material of 6-inch-minus size. Changing the arrangement of the cutting teeth results in material that is larger or smaller. The machine uses a combination of four, 36-inch proprietary cutter chains and special carbide teeth. Each cutter, 13 inches wide with a maximum cutting depth of 42 inches, crushes the rock as it is excavated, delivers it to the main conveyor, discharges material to the left or the right secondary conveyor, and then loads trucks or places windrow. The Rock Miner was primarily designed to excavate materials from locations where drilling and blasting are not possible.
