Hydraulic Bolt Buster
Product Introduction
The Hydraulic Bolt Buster MC2-150B is a specialized hydraulic tool developed by Hefei Chunhua Hoisting Machinery Co., Ltd. for removing liner bolts during ball mill maintenance. Designed to improve the efficiency of traditional manual impact-based bolt removal, it helps shorten mill relining downtime, reduce labor intensity, and improve operational safety.
Based on more than ten years of bolt punch manufacturing experience, the MC2-150B features a redesigned hydraulic system, structural components, and electrical controls. According to the company’s product information, removing liner bolts during the relining of a medium-sized or large ball mill can be reduced from approximately 15–20 days using traditional methods to around 5 days with this equipment.
The MC2-150B delivers high impact force, precise positioning, and recoil reduction. Equipped with horizontal and vertical spreaders and guide sleeves, it is designed to remove both horizontal and vertical liner bolts.
Key Features
- High Impact Force: Provides a maximum vertical impact energy of 360 J and horizontal impact energy of 1,800 J to support efficient liner bolt removal.
- Recoil Reduction: An air-cushion spring and nitrogen-assisted buffering system help reduce recoil during impact, improving operator comfort and safety.
- Horizontal and Vertical Bolt Removal: Dedicated horizontal and vertical spreaders, combined with guide sleeves, help position the tool for different bolt orientations.
- Energy-Efficient Hydraulic System: An electric motor drives the hydraulic system, while variable hydraulic control helps reduce heat generation and operating noise.
- Enhanced Electrical Protection: Features include phase-sequence protection, hydraulic oil temperature indication, oil-level protection, electrical fault protection, oil-return indication, and an emergency stop switch.
- Durable Construction and Easy Maintenance: Structural components are laser-cut, welded, surface-treated, and powder-coated. The design emphasizes reliable operation and straightforward maintenance.

Working Principle
The MC2-150B uses an electric motor to drive a hydraulic pump, which supplies pressurized oil to the hydraulic impact mechanism. The mechanism converts hydraulic energy into impact energy to loosen and remove mill liner bolts.
During operation, the operator positions the bolt punch using the appropriate horizontal or vertical spreader. A guide sleeve assists with alignment, helping the impact mechanism engage the target bolt accurately. The equipment supports both intermittent and continuous impact operation to suit different working requirements.
An air-cushion spring and nitrogen-assisted buffering system help absorb recoil generated during impact. Electrical and hydraulic protection functions monitor relevant operating conditions and help prevent damage caused by incorrect phase sequence, abnormal oil levels, or other electrical and hydraulic issues.
Applications
The Hydraulic Bolt Buster MC2-150B is primarily designed for mill maintenance and liner replacement operations, including:
- Ball Mill Relining: Removing liner bolts during scheduled ball mill maintenance.
- Large and Medium-Sized Mills: Supporting bolt removal in mining and mineral-processing operations.
- Mining and Mineral Processing Plants: Helping reduce maintenance downtime and manual impact work.
- Metallurgical and Related Industries: Supporting mill maintenance where liner bolt removal is required.
The actual suitability of the equipment depends on bolt dimensions, bolt orientation, mill configuration, and site operating conditions.
