A vibrator head is the working component of internal vibrators that transfers mechanical vibrations into concrete to eliminate air pockets and ensure proper consolidation.
The vibrator head is a critical component in internal vibrators used for concrete consolidation. It consists of a hardened steel casing containing an eccentric weight mechanism driven by a flexible shaft or electric motor. When rotated at high speeds (typically 9,000-15,000 RPM), the eccentric weight creates centrifugal force that generates high-frequency vibrations. These vibrations are transmitted through the head's surface into the concrete mix, causing particles to rearrange and air bubbles to rise to the surface. The head's design features include specific diameter-to-length ratios, hardened steel construction for wear resistance, and sealed bearings to prevent concrete ingress.

Most vibrator heads operate between 9,000-15,000 RPM. Higher frequencies (12,000+ RPM) work best for stiff mixes with small aggregates, while lower frequencies (9,000-12,000 RPM) are suitable for standard concrete mixes.
Avoid hitting reinforcement bars, operate continuously when immersed in concrete, withdraw slowly to prevent air pockets, and clean thoroughly after each use. Regular inspection for wear and proper lubrication of connections are essential.
Yes, vibrator heads are compatible with flexible shaft drives (gasoline or electric motors) and direct electric vibrators, provided the frequency and torque specifications match the power source capabilities.
