Surface Plate Vibrator

The surface vibrators commonly used are pan vibrators and vibrating screeds. The main application of this type of vibrator is in the compaction of small slabs, not exceeding 150 mm in thickness, and patching and repair work of pavement slabs. The operating frequency is about 4000 rpm at an acceleration of 4g to 9g.As wet concrete is poured, air bubbles become trapped within the mixture creating cavities or honeycomb-like spaces. Left untouched, “honeycombing” can compromise the cement's longevity and strength. Vibrators force the trapped air out of the mixture leaving the final product a more compact and level slab.
