Vibratory crushing apparatus is disclosed including a mandrel support housing suspended on a frame structure and providing floating support for a vertically arranged mandrel. Upper and lower collar housings are arranged upon the mandrel support housing and define upper and lower faces for crushing interaction with the mandrel. A shaft extends along the mandrel axis on bearings with opposed eccentric masses attached to its ends by hinges. The circumferential face on the upper collar is tapered for receiving relatively large materials to be crushed. Components of the crusher are of modular construction to facilitate repair and maintenance and a cylindrical ring secured to a central portion of the mandrel functions in combination with the upper and lower collar members to form a passage for conducting material to be crushed through the apparatus. With the mandrel and circumferential faces of the upper and lower collars being cylindrical, a resilient coupling is provided between a portion of the mandrel and a generally non-rotating portion of the apparatus to resist rotation of the mandrel.
