Uneven pressure crushing type return flow tunneling machine
The tip of the tunneling machine is equipped with a spoke-shaped cutter and a cone crusher, and by using powerful eccentric rotation, it can excavate all types of soil.
Product Features and Overview
Uncle Mole is a gravel-crushing tunneling machine that is equipped with a cone crusher at the tip of the tunneling machine and can crush boulders and gravel by performing a powerful eccentric rotation motion. It can handle soft ground to hard soil (N value 50 or more) and high water content gravel layers, and can process gravel and boulders up to 40% of their nominal diameter (UCS 200MN/m2). In addition, there is a spoke-shaped cutter at the front of the tunneling machine, which can cut soft rocks with a uniaxial compressive strength of about 5MN/m2.
