The Process of Recycling with the Extec C12 Crusher
The Extec C12 crusher is a powerful mobile jaw crusher designed for heavy-duty recycling and demolition applications. Its robust construction and high-performance capabilities make it ideal for processing concrete, asphalt, bricks, and other construction waste into reusable materials. Below is a detailed breakdown of the recycling process using the Extec C12 crusher.
1. Material Preparation
Before feeding materials into the crusher, proper preparation is essential. Large chunks of concrete or asphalt may need to be broken down using hydraulic breakers or pulverizers to ensure they fit into the crusher’s feed opening. Contaminants such as rebar, wood, or plastic should be removed to prevent damage to the crusher’s components and ensure clean recycled output.

2. Feeding the Crusher
The prepared material is loaded into the Extec C12’s hopper using an excavator or wheel loader. The crusher features a large feed opening (1200mm x 750mm), allowing it to handle sizable debris efficiently. A vibrating grizzly feeder ensures consistent material flow into the crushing chamber, reducing blockages and optimizing productivity.

3. Crushing Process
Once inside, the material is crushed between the fixed and movable jaw plates. The Extec C12 utilizes a high-inertia flywheel and a hydraulic drive system to deliver strong crushing forces, breaking down hard materials effectively. Adjustable jaw settings allow operators to control the output size, producing either coarse aggregates for road base or finer materials for reuse in new concrete mixes.
4. Separation of Reinforcements
Many demolition materials contain embedded steel reinforcements (rebar). The Extec C12 includes an overband magnet that automatically separates ferrous metals from crushed aggregate during operation. This ensures cleaner recycled material while allowing recovered metal to be sold separately as scrap.
5. Screening and Grading (Optional)
For projects requiring precise sizing, crushed material can be passed through an optional screen attachment or a separate screening plant. This step further refines aggregates into specific grades suitable for various construction applications, such as drainage layers or sub-base materials.
6 Stockpiling Recycled Aggregates
Processed aggregates are discharged via an extended conveyor belt system included with the Extec C12 crusher—typically reaching lengths up to 9 meters—allowing stockpiling at a distance from the machine for efficient loading onto trucks or direct reuse onsite in new
