The Unclemole was developed by Iseki Poly-Tech,Inc., originally to meet the demand for small-bore tunnelling in difficult ground conditions, then was improved to broaden the range of application.
Unclemole is basically slurry shield that utilizes slurry to transport excavated material,
and has built-in cone crusher in the front part to cope with hard ground involving cobbles
The crushing structure has capability of crushing particles up to 30 percent of the outside
diameter into fragments small enough for transportation as slurry.
