thyssenkrupp impact crushers for the aggregates and mining industries Wherever medium-hard and hard rock is processed into gravel, chippings or sand, impact crushers from thyssenkrupp can contribute to efficient operation. The material is fed through the feed opening into the crusher and is hit by the blow bars fixed in the rotor. Here the material is crushed by the large kinetic energy of the blow bars hitting the rocks. The material is crushed at the natural fracture surfaces and thrown against the first or second impact apron, where it is crushed further. From here, the material is deflected to the impact circle of the rotor. This process is repeated until the crushed material passes through the adjustable gap between the impact apron and rotor and is finally discharged through the bottom of the machine. The impact aprons of the crusher can be adjusted hydraulically from the outside. This enables the crushing chamber to be quickly adapted to the operator's requirements. When non-breakable tramp metal enters the crushing chamber, the impact aprons retract to the rear wall of the housing. Optionally, a grinding path can be installed in primary and secondary impact crushers, which introduces a further crushing stage in the machine. Essentially, the grinding path limits the maximum grain size of the product and produces a product with high cubicity. The product from impact crushers ensures high stability in road construction and concrete due to its cubicity and absence of cracks and residual stress.
