Liner Bolt Punch | MC2-150B Ball Mill Liner Bolt Removal Tool
The MC2-150B Hydraulic Bolt Impact Wrench is designed for liner replacement in medium and large ball mills. It uses a motor-driven variable hydraulic system, combined with air damping buffer and hydraulic vibration technology, to quickly remove liner bolts installed in both horizontal and vertical directions.
Compared with traditional manual hammering, it shortens the liner bolt removal time for a medium-sized mill from 15–20 days to about 5 days, with sufficient impact force, no obvious recoil, and precise positioning.

Q1: Which mills is it suitable for?
A: Medium and large ball mills. Provide your mill model for compatibility evaluation.
Q2: Can liner replacement really be shortened to 5 days?
A: For a medium-sized mill, liner bolt removal takes about 5 days, depending on mill size, bolt corrosion, and site conditions.
Q3: Can it remove both horizontal and vertical bolts?
A: Yes. It comes with horizontal and vertical lifting fixtures plus guide sleeves for positioning.
Q4: Is there any recoil?
A: The rear of the impact body is equipped with an air damping buffer spring and nitrogen charge, so the operator feels no obvious recoil.
Q5: Do you support trial operation or customization?
A: Yes. On-site trial operation and working condition evaluation are supported. Impact rods and lifting fixtures can be customized to mill specifications.
