It is suitable for many medium-hard and softer materials, including limestone, concrete, asphalt, and selected construction and demolition waste. The suitability of highly abrasive or exceptionally hard rock should be evaluated before equipment selection.
Select the crusher according to the material’s hardness and abrasiveness, maintain consistent feeding, inspect blow bars and liners regularly, and use suitable wear materials. Proper operating settings can also help reduce unnecessary wear and downtime.
Final product size is influenced by rotor speed, crusher settings, feed characteristics, and screening arrangements. A properly designed crushing and screening circuit helps maintain the required product grading.
Yes. It can process suitable concrete rubble, masonry, and other selected demolition materials. Depending on the project, magnetic separators, screening units, and dust suppression systems can be incorporated into the configuration.
An impact crusher can produce well-shaped, cubical aggregates and achieve a high reduction ratio. It is often selected for applications where particle shape and the production of finished aggregates are important.
This depends heavily on material hardness and cleanliness. When processing clean limestone, a set of blowbars can often process 20,000 to 40,000 tons before turning. When crushing highly contaminated urban demolition waste or concrete with high silica content, blowbars may need to be flipped or replaced every 10,000 to 15,000 tons to maintain cutting efficiency.
The concrete blocks enter the impact chamber where the high-speed blowbars shatter the concrete clean away from the metal. The freed rebar passes under a specialized rubber deflector plate that straightens the metal out before it lands on the product belt, where a powerful over-belt magnet extracts it cleanly into a separate scrap pile.
Choose an impact crusher if you are working with soft to medium rock (like limestone) or recycling materials and need a high reduction ratio with a perfectly cubical shape. Choose a cone crusher if you are working with highly abrasive, hard materials like granite or basalt, as cone liners tolerate high silica contents much better than impact blowbars.
