Handling reinforced concrete is the toughest part of C&D recycling. The steel inside wants to destroy your crusher, and abrasive materials eat away at your wear parts. Your choice of primary crusher decides how you handle these challenges.
It usually comes down to a choice between compression (a كسارة الفك المتنقلة) and impact (a كسارة تصادمية متنقلة). One handles hard, oversized feed better; the other produces a higher-value sellable aggregate. We analyze the strengths and weaknesses of both to help you match the right machine to your material.”
1. Mobile Jaw Crusher
كسارات الفك الاستخدام compression force to break material between a fixed and a moving manganese plate.
Why choose it for C&D Waste?
- Handling Oversized Feed: If your waste stream includes massive concrete slabs, bridge pillars, or large foundation blocks, a Jaw crusher (like the SUHMAN Dual-Core series) is indispensable. It has a larger feed opening relative to its size.
- تكاليف التشغيل المنخفضة: Jaw plates wear down much slower than impactor blow bars. If your concrete has high “abrasiveness” (e.g., contains high-silica river gravel), the jaw crusher will save you a fortune in wear parts.
- مصداقية: It is less sensitive to uncrushable items that occasionally slip through pre-sorting.
The Trade-off:
- Output Shape: The crushed material can be “flaky” or elongated, which may not meet premium road-base specifications without secondary processing.
- Rebar Liberation: While it breaks the concrete, it doesn’t always “strip” the rebar cleanly, making magnetic separation slightly less efficient.
2. Mobile Impact Crusher
Impactors use high-speed kinetic energy. Blow bars on a spinning rotor fling the material against impact plates (aprons), shattering it along natural cleavage planes.
Why choose it for C&D Waste?
- Superior Grain Shape: If you are selling recycled aggregate for high-grade concrete or asphalt, the Impact crusher is king. It produces a cubical, high-quality product في مسار واحد.
- Excellent Rebar Liberation: The violent impact force is highly effective at shaking concrete loose from steel reinforcement. This allows your overbelt magnet to recover clean, high-value scrap metal.
- نسبة تخفيض عالية: It can often turn large waste into a finished product size in one step, potentially eliminating the need for a secondary crusher.
The Trade-off:
- Wear Costs: If the feed is highly abrasive, the blow bars will wear out quickly, increasing your cost-per-ton.
