Abstract: A rotor of an impact crusher has at least one stellate plate, which can be attached to the rotor shaft. A plurality of paddle-blade type hammer tools are mounted on each stellate plate. The hammer tools are secured above and below the stellate plate by tool mounting brackets having hook-shaped ends that engage with the hammer tools. A respective adapter piece is placed in the stellate plate between the two tool mounting brackets. A retaining bolt penetrates the two tool mounting brackets and the adapter piece. A security slide secures the retaining bolt in position. The hammer tools of the inventive rotor for an impact crusher have a high usage volume and the rotor is extremely user-friendly with respect to the recurring tasks of setting and replacing the hammer tools, without having to loosen screw connections.

Abstract: A reliable, inexpensive option for the plates that function as wear parts and are mounted on an inner face of a casting wall of a stator. To achieve this the plates are designed as cast parts and are fixed to the inner face of the casting wall from an exterior of the stator. The plates are fixed by fixing bolts, which are screwed into the plates through the casting wall from the exterior. The plates have transverse threaded bores that correspond to the bolts. Respective spacer rings are pushed onto the fixing bolts secured by wedge-shaped cotters in both a positive and non-positive fit, and the wedge-shaped cotter pressing on the spacer rings that lie against the outer face of the casting wall. This invention is extremely economical and improves the operational safety in comparison to known options.
