Description
In addition to their trench excavation capabilities, the EK chain cutters are also suitable for mining medium-hard minerals with compressive strengths ranging from 15 to 60 MPa, where drill and blast methods are not feasible. This makes them a versatile tool for a variety of excavation and mining projects.
One of the key benefits of the EK chain cutters is that they reduce wear and tear on the excavator swing gear, as well as providing a 40% energy saving for equivalent production rates compared to conventional rotary drum cutters without the central chain. This makes them a cost-effective and environmentally friendly choice for contractors and construction companies.
In summary, the Kemroc EK chain cutters are a cutting-edge solution for excavation and mining projects. With their patented cutting attachment, efficient and vibration-free operation, and ability to reduce wear and tear on excavator swing gear, they are a must-have tool for any contractor or construction company looking to enhance their operations
