Double Toothed Roll Crusher
Double toothed roll crushers are often placed at the start of construction waste processing, where large concrete pieces need to be broken down before the steel bars and aggregates can be separated. Two toothed rollers pull the material into the crushing area, where the teeth grip, squeeze, and break the concrete into smaller pieces. During this process, the reinforced concrete is loosened from the steel bars, making both materials easier to separate and recover in the next steps. This type of crusher is suitable for reducing large demolition debris before screening, metal separation, or recycled aggregate processing.

Crushing Teeth
Replaceable crushing teeth can be changed individually as wear parts, without replacing the full roller body. This helps reduce maintenance costs and keeps the crusher easier to service over long-term operation.

Drive System
The two-stage transmission system provides strong output torque with lower power loss, supporting stable capacity and efficient crushing during construction waste processing.
Controlled and Uniform Output Size
The roller gap can be adjusted to control the final output size. After crushing, the material has a more uniform particle size and shape, with less over-crushing, which helps improve the quality of recycled aggregates.
Compact Structure
The integrated structure takes up less space and is easier to arrange in fixed, modular, or mobile crushing and screening lines for construction waste recycling projects.
