The 12HM46 continuous miner, with a dual gathering head system, is ideal for industrial mineral mining applications, including trona, gypsum, potash, and salt. The 12HM46, with a 1473 mm (58 in.) cutter head diameter, is the largest and most powerful drum-style continuous miner in our product lineup. With a machine mass of 154,000 kg (340,000 lbs.) and a maximum cutting height of 6.0 m (20 ft.), the 12HM46 has what it takes to increase production in the tough industrial mineral cutting environment.
Cutting system
The 12HM46 is a Ripperveyor cutting head system, with a variety of cutter bit lacing configurations available.
Bolted construction
Since many industrial mineral mines have shaft restrictions, the 12HM46 comes in several bolted configurations to accommodate these restrictions. This continuous miner is designed to be assembled on site without, or with very limited, component welding.
