MC3-250C Hydraulic Bolt Punch for Ball Mill Liner Replacement

MC3-250C Hydraulic Bolt Punch Mining Tool For Ball Mill Liner Bolt Removal And Replacement

The MC3-250C hydraulic bolt punch is heavy-duty equipment designed to remove seized liner bolts during ball mill and SAG mill liner replacement. It delivers powerful hydraulic impact with low recoil, simple operation and stable performance. It effectively cuts mill downtime, improves operational safety and boosts working efficiency for mining concentrators.

The traditional method for removing liner bolts mostly relies on manual striking, which comes with low efficiency, heavy labor intensity, potential safety hazards and long liner replacement cycles with outdated technology. For a medium-sized mill, bolt removal normally takes 15 to 20 days. This machine can greatly shorten the downtime of ball mills and semi-autogenous mills during liner replacement, improving on-site safety and working efficiency at mining plants.

Our MC2-150B hydraulic bolt impact tool is developed to improve the conventional bolt removal method and shorten the liner replacement time of mills. When replacing liners for a medium-to-large ball mill, bolt removal only takes 5 days. It significantly increases equipment availability and brings higher economic benefits to customers.

Product Advantages

Powerful hydraulic impact force, no recoil for safe operation

Simple structure, easy positioning and on-site operation

Shorten mill liner replacement time, reduce equipment downtime

Durable structure, suitable for heavy-duty mining working conditions

Main Performance Features

Structural components are processed by laser cutting, welding, shot blasting and assembly-line plastic spraying. The coating features strong adhesion, smooth surface and good fade resistance.

The impact body is the core part. Its valve core and sealing kits are imported from South Korea, delivering stable hydraulic pressure. Vertical impact energy reaches 3600J and horizontal impact energy 1500J. It supports jog or continuous striking.

A nitrogen-filled air buffer spring is fitted at the rear to greatly reduce recoil and protect operator safety.

The electric control system has main on/off control and phase sequence protector to avoid oil pump reverse rotation. It is equipped with high-pressure alarm, status indicators and emergency stop button.
