Circling roots can be found on container-grown trees, field-grown (balled-in-burlap, or B&B) trees, or bare-root trees. Eliminate this root defect by cutting roots at planting. First, carefully remove the soil from around the base of ...

It was observed that the torque required to cut the plastic with this shredder was lower than that of the impact crusher. As a result, the overall mechanical complexity and cost of grinding are reduced.
