TWO-ARBOR VIBRATION EXCITER WITH THE VARIABLE AMPLITUDE OF VIBRATIONS Russian patent published in 2006 - IPC B06B1/16 B28B1/87 

FIELD: construction materials industry; equipment for production of the construction materials and constructions.

SUBSTANCE: the invention is pertaining to production of construction materials and constructions and is intended for blowout of the cellular concrete admixtures in the mold. Substance: the vibroplatform is equipped with the two-arbor vibration exciter. The vibration exciter operation is automatically controlled by two synchro-tracking systems under the program forming the rule of the variation of the frequency and the amplitude of the vibrations. The device allows to control automatically the frequency and the amplitude of the vibration exciter vibrations. The technical result of the invention is the increase of the indexes of the cellular concrete products strength, savings of the electrical power and the construction materials, which are the components of the cellular concrete admixture, reduction of the duration of the vibration blowout of the cellular concrete.

EFFECT: the invention ensures the increase of the indexes of the cellular concrete products strength, savings of the electrical power and the construction materials - the components of the cellular concrete admixture, reduction of the duration of the vibration blowout of the cellular concrete.
