The vibrations of vibratory tables are often imparted by means of off-balance masses rotating on a shaft, but many other mechanisms are also widely used according to the usage. For example, densification needs in the refractory industry have demands above 3600 RPM, rotary air units are used to achieve this. The air-operated unit’s intensity can be varied by changing input air pressure with a pressure regulator. Types of Vibratory Tables

Other characteristics

Typically a shallow-type mould will usually take between 45 seconds to a minute and a half to vibrate, although this greatly depends on how wet or dry the mixture is. Leaving the mould on the table shall then allow the air bubbles to escape by coming to the surface.
