What Is The Oldest and Most Sturdy Crusher?

The oldest and most sturdy crusher jaw crusher. Jaw crusher (jaw crusher) feeding from the top of the entrance, the material poured into the crushing chamber containing jaw teeth. Jaw teeth with great force the material to the top to the wall, broken into smaller stones. The jaw teeth movement is an eccentric shaft, the axis runs through the framework of the fuselage. The eccentric motion is usually fixed to the shaft at both ends of the flywheel generated. Flywheel and often eccentric support bearing spherical roller bearings, bearing extremely harsh working environment.

Construction materials are increasingly judged by their ecological characteristics. Concrete recycling gains importance because it protects natural resources and eliminates the need for disposal by using the readily available concrete as an aggregate source for new concrete or other applications. According to a 2004 FHWA study, 38 states recycle concrete as an aggregate base; 11 recycle it into new portland cement concrete. The states that do use recycled concrete aggregate (RCA) in new concrete report that concrete with RCA performs equal to concrete with natural aggregates. Most agencies specify using the material directly in the project that is being reconstructed.

Ore dressing plant generally adopts three phase crushing process to crush ore: coarse-crushing, medium-crushing and fine-crushing. The most commonly used ore crushers or minetal crushers are jaw crusher, hammer crusher,impact crusher and cone crusher. 2.1m or 2.2m gyratory crusher is often used in coarse crushing (primary crushing), while 2.1m or 2.2m standard cone crusher for medium crushing, and 2.1m or 2.2m short-head type cone crusher for fine crushing. Through the coarse crushing, the size of ore is less than 1m, and after medium crushing and fine crushing, the size becomes less than 12mm.
