An invention relates to the industry of building materials and can be used for vibroimpact compaction of different building items. The purpose of the invention is development of automatically controlled equipment for antiphase vibroimpact compaction where static and dynamic forces to molding material are applied independently and during the process of compaction the equipment itself adapts to the compaction degree of material, and thereby the power resource is utilised as effectively as possible. The proposed equipment (fig.1) comprises the pressmold filled with molding material, two dies that act on molding material from opposite sides, the hydrodrive of the dies, two strikers, the hydraulic cylinders as vibrators and flow control distributor. Novelty of the invention is characterised in that the equipment is provided with a measuring system of relative displacements of strikers and dies, as well as with a control system of flow distributor in order to control the action of hydraulic cylinders as vibrators.
