1. A rock crushing device, comprising:
(a) a housing including at least two walls defining a chamber having an upper inlet and a lower outlet, said at least two walls having a rock-crushing surface connected therewith, at least one of said walls being movable relative to another one of said walls to define a primary compression assembly for crushing rocks within said chamber via mechanical force; and
(b) an independently operated auxiliary crushing assembly including a vibratory pad being connected with at least one of said at least two walls to deliver vibrations to said at least one wall for crushing rocks within said chamber via vibratory force, said vibratory pad being operated by a piezoelectric or a hydraulic force, said auxiliary crushing assembly being operable one of together with and independent of said primary compression assembly, whereby when rocks are inserted into the upper inlet of the rock crushing device and the rocks are crushed by the primary compression assembly and the auxiliary crushing assembly, the vibratory force of the auxiliary crushing assembly causes successive stress peaks that are greater than the stress peaks caused by the force of the primary compression assembly, thereby reaching a rock fracturing threshold in less time than the primary compression assembly alone.
