- Potential production increase up to 70%*
*Compared to 12HM26/12HM27/12HM36
Product Features and benefits:
Corrosion Protection: Guard against corrosion, a common issue in industrial mineral operations, with specially designed pins and bushings.
Closed Loop Cooling: Ensure environmental responsibility by using a closed loop cooling system in 12HM continuous miners to prevent discharging cooling water onto extracted material.
Applicable in Industrial Minerals: Specifically crafted for challenging industrial minerals applications such as salt, potash, trona, and gypsum.
High Production: Engineered for maximum productivity, the 12HM46 continuous miner boasts the highest mass and installed cutting power, reaching up to 850 kW (1,140 HP).
Drill and Blast Alternative: Offering a highly efficient alternative to traditional drill and blast mining systems, continuous miners streamline the mining process.
Adaptability: Choose from multiple models of Joy 12HM continuous miners, suitable for seams ranging from 2 to 6 meters (79 to 236 inches).
