Hydraulic Bolt Punch High Impact No Recoil for Mill Liner Replacement Machine

MC2-150B Hydraulic Bolt Punch High Impact No Recoil For Ball Mill Liner Replacement

The MC2-150B Hydraulic Bolt Impact Tool is special equipment designed to remove liner bolts when replacing ball mill liners. Featuring powerful impact force, no recoil, precise positioning and simple operation.

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which comes with low efficiency, heavy labor intensity, potential safety hazards and long liner replacement cycles with outdated technology.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.

Main Performance Features

• Structural components are processed by laser cutting, semi-automatic & automatic welding, shot blasting and assembly-line plastic spraying. The coating features strong adhesion, smooth and glossy surface, long service life and anti-fading property.
• The impact body is the core component. Its cylinder valve core and complete sealing kits are imported from South Korea with Korean technology. It boasts excellent pressure, wear and high temperature resistance. The hydraulic pressure stays stable during operation. Vertical impact energy reaches 3600J and horizontal impact energy 1500J. It supports jog or continuous striking for higher efficiency.
• Safety is prioritized. A nitrogen-filled air damping buffer spring is installed at the rear of impact body to greatly reduce recoil. Operators will not feel obvious rebound during operation for personal safety.
• The electric control system adopts main on/off control and phase sequence protector to avoid oil pump reverse rotation. It is equipped with high-pressure alarm, operation & oil return indicators and emergency stop button. Power supply: 380V, 50Hz.
• The power system is driven by an electric motor with no harmful gas emissions. The hydraulic system adopts a variable displacement system, featuring low heat generation, low noise and energy-saving & environmental-friendly performance.
• It boasts a high degree of intelligence, integrating hydraulic control technology and hydraulic vibration technology.
• The bolt impactor is equipped with horizontal and vertical lifting tools. With the auxiliary function of the guide sleeve, it can smoothly remove horizontal and vertical bolts.
• The complete machine is economical and practical, with exquisite design, reliable quality, simple maintenance, comfortable operating environment and low labor intensity.
