Hydraulic crusher: efficient processing of concrete counterweights and metal recycling

In the ship dismantling industry, there are often concrete counterweight structures or isolation walls inside the hull, which are designed to enhance ship stability or separate functional areas. However, traditional dismantling methods face problems such as mixing concrete and metal, low operational efficiency, and resource waste. hydraulic crusher, with their precise crushing and efficient separation capabilities, have become practical tools in ship dismantling scenarios.

1.The core function of hydraulic crusher in ship dismantling

Concrete counterweight crushing

The concrete counterweights at the bottom of the ship are usually large in volume and high in density, making it difficult for traditional crushing equipment to handle them directly. The hydraulic crusher, with their multi jaw tooth structure and high-pressure design, can gradually crush concrete blocks while reducing damage to the surrounding ship’s steel structure.

Dismantling of isolation structure

Concrete isolation walls or fire-resistant structures are often used in the internal compartments of ships. hydraulic crusher can adjust the opening and closing angle of the jaws to perform targeted crushing on specific areas, while retaining the available metal frame and reducing overall disassembly costs.

Metal component recycling assistance

During the process of crushing concrete, the steel bar cutting function built into the hydraulic crushing pliers can synchronously cut off metal connectors such as steel bars and bolts embedded in the concrete, achieving rapid separation of concrete fragments from metal materials and improving recycling efficiency.

2.Technological advantages and adaptability

Flexibility and controllability

hydraulic crusher support 360 ° rotation operation, suitable for narrow spaces or complex structural environments inside ships. Operators can precisely control the crushing force and range through excavators to avoid accidental damage to key parts of the ship.

Wear resistance and durability

In response to the high-strength wear of concrete and metal mixtures in ship dismantling, the hydraulic crusher are designed with double-layer wear-resistant steel plates and spiral teeth to extend the service life of the equipment and reduce maintenance costs for frequent component replacement.

Environmental Protection and Safety

Mechanized operations reduce the need for manual entry into high-risk areas and lower operational risks. At the same time, the efficient separation of concrete and metal reduces the generation of mixed waste, which meets the requirements of resource recycling and environmental regulations.

3.Example of practical application scenarios

Dismantling the bottom weight of the ship: Hydraulic crushing pliers gradually crush concrete blocks, releasing internal metal anchor chains or steel plates for easy classification and recycling.

Cleaning the isolation compartment: For the concrete partition walls inside the compartment, local crushing is used to preserve the integrity of the steel structure and shorten the dismantling cycle.

Disposal of abandoned pipeline foundation: Crush the concrete foundation and cut off the fixed steel bars, quickly recover the metal materials of the pipeline.
