What you should know about Vibrator

What is a needle vibrante ? The vibrating needle finds its place in the world of building and public works. It is a device used to place concrete. To do so, it emits a vibration per minute by making a rotating movement on its spherical or conical head. It is presented in cylindrical form. Use and application of a vibrating needle The spherical head is planted on the concrete surface. The motorization will then be in charge of timing the vibration. The objective is to penetrate the hard surface. Note that it is advisable to stop the vibration after a certain period of time to prevent segregation of the material. When concrete is poured into formwork, it is essential to establish vibration. The explanation is that this will promote grain accommodation. The vibration gives the concrete its homogeneity. As a result, the cement will be more durable over time. Indeed, the pulsation expels the air pockets accumulated during mixing to the outside. The different types of vibrating needles The vibrating needle is available in two versions. There is the pneumatic and the electric vibrating needle. The pneumatic vibrator is equipped with a compressor. In turn, the electric vibrating rod is powered by an electric motor. The latter is located on the gun. (1)
