Abstract
The invention relates to a compressing device for performing compression operations on shaped bodies made of grainy materials. The grainy materials, e.g. wet concrete mortar, are formed into shaped bodies in the mold recesses (106) of the mold boxes by applying vibrations and compression pressure. The invention aims at providing a low-noise low-energy consuming compressing device. In order to achieve a low-noise compression operation, said mold box (106) and vibrating table (124) are rigidly clamped together and harmonic vibrating operation of the vibrating mass-spring-system is ensured. Reduced energy use and effective compression is promoted by applying a vibrating frequency, said frequency being at least partially in the range of the resonance frequency of the
