The Extec C13 (2006): A Mobile Impact Crusher of Its Era
Emerging onto the scene in the mid-2000s, the Extec C13 mobile tracked impact crusher represented a significant step forward in on-site processing capabilities for contractors and recyclers seeking flexibility and productivity. Designed as a robust secondary or tertiary crusher, the 2006 model year C13 encapsulated the engineering priorities of its time: power, mobility, and versatility.
Core Specifications & Design:
Engine: Typically powered by a CAT C13 ACERT diesel engine (approx. 328 kW / 440 hp), providing ample power for demanding crushing tasks.
Crusher Unit: Featured a large horizontal shaft impactor (HSI) with either 4 or 6 hammers/blow bars (depending on configuration). The rotor diameter was substantial (approx. 1270mm / 50″), designed to handle significant feed sizes.
Feed Opening: A generous feed opening allowed the processing of bulkier materials like demolition concrete, asphalt slabs, and natural rock.
Pre-Screen Option: A key feature enhancing efficiency was the optional independent double-deck pre-screen. This allowed operators to scalp fines before the crusher chamber significantly reducing wear on the impactor and improving final product quality by removing undersized material upfront.
Mobility: Built on a robust tracked undercarriage, offering good mobility around site and relatively easy setup compared to static plants.
Conveying System: Equipped with integrated product conveyors – typically a main discharge conveyor capable of radial movement and often an optional side conveyor for stockpiling different fractions or removing screened fines.
Target Applications:
The C13 excelled in several key areas:
1. Construction & Demolition (C&D) Recycling: Its ability to crush reinforced concrete, bricks, and asphalt made it ideal for processing demolition waste directly on-site into valuable recycled aggregates.
2. Asphalt Recycling: Efficiently processed reclaimed asphalt pavement (RAP) into consistent sizes suitable for reuse in new asphalt mixes.
3. Natural Rock Processing: Capable of handling limestone and other medium-hard rock types as a secondary crusher after primary jaw crushing.
4. Topsoil & Compost Production: When fitted with specific screening media/grids on the pre-screen box.
Operational Characteristics:
Output Capacity: Depending heavily on feed material type and size
