A hydraulic pulverizer is a demolition attachment that uses hydraulic power to crush and pulverize concrete and other materials. It is commonly used on excavators and can help with breaking down concrete structures, recycling materials, and separating rebar from concrete.

The hydraulic pulverizer operates by using hydraulic pressure to power two jaws or blades that move in a scissor-like motion. These jaws crush and shear the material, reducing it to smaller, more manageable pieces. The hydraulic system provides the force needed to handle tough materials.

Hydraulic pulverizers are designed primarily for concrete and reinforced concrete structures. They can also handle masonry and other demolition debris. Some models are equipped to handle mixed materials with rebar.

The size of the excavator required depends on the size and capacity of the pulverizer. Pulverizers are available in various sizes to match different excavator models, ranging from small units for mini-excavators to larger models for heavy-duty machines.

Consider the following factors:

• Size and weight of the pulverizer: Match it with the size and capacity of your excavator.
• Material types: Ensure the pulverizer is suitable for the materials you will be processing.
• Features: Some pulverizers come with additional features like rotation or interchangeable jaws for different tasks.

• Efficiency: It speeds up the demolition process and reduces material to manageable sizes.
• Versatility: Capable of handling various types of materials.
• Recycling: Facilitates the recycling of concrete and other materials by separating rebar and reducing waste.
• Precision: Provides controlled crushing, which helps in more precise demolition and material handling.
