A pneumatic turbine vibrator plays an important role when it comes to preventing materials from sticking to hopper walls or the sieve. They are typically used in the pharmaceutical and food-processing industries. The units produce multi-directional vibrations and their range of applications include:

– Intermediate hoppers
– Vibrating tables
– Emptying silos
– Sifters
– Activating vibrating trays
– Transporting bulk materials
– Reduce friction

Pneumatic turbine vibrators are ideal for humid or explosive environments. They can be used outdoors for a variety of applications. Depending on the brand, some of the pneumatic turbine vibrators available on the market use pressure service to determine both centrifugal and frequency force.

The best products are manufactured in accordance with machine directive (89/392/EEC EN 292 standards). This applies to components, such as turbine, roller and ball. On the other hand, the main benefits of these turbine vibrators include no maintenance, price, operating temperature (4°F to 250°F or 20°C to 120°C), no lubrication, robustness and presence of an explosion roof.

Silent operation

Pneumatic turbine vibrators are designed to operate silently. They hover between 65 and 75 dB in the course of their entire service life. Meanwhile, ball vibrators tend to make increased noise as the ball and ballrace becomes pitted. They are known to reach 100 dB.

The pneumatic turbine variants are well suited to chutes, small bins, hoppers and other applications involving light material handling. They can be used on any new or existing installation. The products are a great choice when replacing noisy and messy piston variants.

Some models feature an aluminum housing, threaded exhaust, single-bolt-mount to simplify installation. The silent turbine vibrators are maintenance-free in addition to being a low cost solution. Turbine vibrators are generally more durable when compared to ball variants. They also use 50 percent less air.

Air consumption

Unlike turbine vibrators, ball models draw more air since the balls take up only 1/20 of the space available in the vibrator housing. This means that a lot of air is wasted and exhausted leading to poor air efficiency. The pneumatic turbine vibrator is designed in a way that ensures all air entering the housing contributes towards the rotation of the turbine. The units produce the desired vibration since the turbine fits properly in the housing.

Efficiency and longer life

Turbine units have the capacity to produce high efficiency regardless of age. Ball vibrators usually lose efficiency and speed progressively throughout their service life. This is caused by ball and ballrace pitting. On the other hand, turbine vibrators last longer because there is no metal to metal contact. They also face a considerably low susceptability to moisture and contamination. The bearings fitted onto the units are pre-lubricated for life.
