General-purpose vibrators

Surface vibrators are used for consolidation of concrete mixtures and ground, facilitation of bulk materials transportation during unloading and screening, etc. A surface vibrator is a three-phase asynchronous electric motor with short-circuit rotor with eccentric weights mounted at both ends of the shaft, which produce driving force.

High-frequency vibrators

High-frequency surface vibrators are used for consolidation of concrete mixtures and ground, facilitation of bulk materials transportation during unloading and screening, driving of vibration feeders, vibration tables, and other types of operation, including mini brick-making machines. A high-frequency vibrator is a three-phase asynchronous electric motor with short-circuit rotor with eccentric weights mounted at both ends of the shaft, which produce driving force. The eccentric weights mounted at both ends of the shaft are made double so as to adjust the magnitude of the driving force. The change in vibration frequency is achieved by changing the angle between the movable and fixed eccentric weights at both ends of the shaft. These vibrators should be used with an adjustable electronic frequency converter, which allows powering of the vibrator with a current
frequency of 100 Hz and 200 Hz.

Long-life surface vibrators

Long-life surface vibrators are designed for utilization in conditions requiring longer operating life (the operating life of classic vibrators is 700 to 900 engine hours; for new series vibrators, the operating life is 5,000 engine hours) and adjustable, high-frequency vibration. The surface vibrators of this series can operate at frequencies up to 100 Hz; the vibrators must be installed at an angle to the horizontal plane or vertically.

Control cabinets

Motor control cabinets (MCC) for electromechanical vibrators mounted at vibration tables and plates
help adjust the vibrators’ operating frequency and control the general operation of the vibrating
equipment.

The simplest solution can only turn equipment on and off. More complex solutions can control and
track any vibrating equipment operating parameters.

MCC advantages:

smooth start;
limitation of starting currents protects the vibrators from turn-on failure;
when the equipment is turned on, there is no mechanical shock, which ensures the mechanical integrity of a vibration table/plate;
adjustment of the vibration frequency allows adapting the vibration processing frequency to the concrete frequency response and the geometry of a concrete product, which, in turn, helps achieve smoother surfaces (which do not require additional plastering), reduce the vibration time of a single product, maintain the mixture’s homogeneity, and reduce cement consumption;
possibility to consolidate rigid concrete mixtures;

DC injection braking allows vibrators to stop immediately. During the turning-off of the vibrators, the equipment does not pass the resonance zone, where the damage to the concrete product and destruction thereof may occur.
