A hammer crusher has a rotor disk centered on and rotatable about an axis, having a predetermined outside diameter, and formed with five angularly equispaced and radially outwardly open pockets. Respective support bolts in the cavities define on rotation of the disk an orbit of generally the same diameter as the predetermined outside disk diameter. Respective hammers pivoted on the bolts project radially from the cavities on rotation of the disk. A pentagonal-section shaft carries the disk and has facets directed radially outwardly at the respective bolts. |
