Trituradora de impacto o trituradora de mandíbulas para materiales de roca dura
por duro, roca altamente abrasiva (granito, basalto, minerales ricos en cuarzo), Una trituradora de mandíbulas es la mejor opción para la trituración primaria., while impact crushers are generally not recommended as the main machine.
When to use a jaw crusher?
- Jaw crushers use compression and are designed specifically to handle very hard, tough materials like granite, basalt and hard ores at the primary stage.
- They accept large feed sizes, have high throughput and lower wear costs in abrasive hard rock compared with impact crushers, though the product is coarser and more flaky.
When (and how) to use an impact crusher？
- Impact crushers rely on high‑speed impact and are best for medium‑hard to soft, less abrasive rock such as limestone, arcilla, and many recycled materials, where they give excellent cubic shape and high reduction ratio.
- Using an impact crusher as the main machine on very hard, abrasive rock quickly wears blow bars and liners, sharply increasing wear‑part cost and downtime; if used, it is usually as a secondary/tertiary stage after a jaw or cone to improve shape.

Preguntas frecuentes: Jaw Crusher vs Impact Crusher
Q1: How do I choose between a jaw crusher and an impact crusher for my material?
A1: The choice mainly depends on material hardness, abrasividad, and your product size requirements. For very hard, roca abrasiva (granito, basalto, cuarzo), a jaw crusher is usually the best primary machine, often followed by a cone crusher. For medium‑hard or softer, less abrasive materials (caliza, residuos de la construcción, asfalto), an impact crusher is ideal for achieving high reduction ratios and good particle shape.
Q2: What information do you need to recommend a suitable crushing solution?
A2: To recommend the right configuration, it is important to know: material type and hardness, maximum feed size, required production capacity (t/h), desired product size range, and any site or mobility constraints. With these details, engineers can match appropriate jaw, cono, and impact crusher models and design a complete, efficient process flow.
Q3: Can one crusher type handle both hard rock and construction waste?
A3: In most cases, a single crusher type cannot work optimally for both extreme hard rock and mixed construction waste. For hard rock, a jaw‑and‑cone combination is usually preferred for durability and lower wear costs. For construction and demolition recycling, a jaw plus impact crusher setup (or a primary impactor) is typically more efficient for handling rebar, producing better‑shaped recycled aggregates, and meeting road base or concrete specifications.
