Pneumatic Roller Vibrators

With just one moving part - a single rotor making an eccentric movement inside a steel race - these Deca Rotary Pneumatic Roller Vibrators deliver high frequencies and high centrifugal forces with relatively low compressed air consumption.

Depending on the size, frequency, and amplitude of the output, they are useful as flow aid devices in bulk material handling bins and hoppers to combat bridging or rat holing of materials.

They are also adaptable for compacting materials in molds and forms in concrete and foundry applications, as well as for screening, sorting, and separation in industrial processing.

DRV SERIES ROTARY PNEUMATIC ROLLER VIBRATORS
(Anodized Aluminum Alloy Body)

The lightweight design of DRV Series Rotary Pneumatic Roller Vibrators is ideal for small bins, hoppers, chutes, and screens handling a wide variety of materials.
  • Capable of generating very high frequencies (up to 29,500 rpm) at low to moderate amplitudes.
  • Variable force output is controlled through air pressure regulation.
  • Delivers rugged, economical performance with little or no maintenance.
  • Standard models are ATEX ExII3D certified.
DR PNEUMATIC EXTERNAL HIGH FREQUENCY ROLLER VIBRATORS
(Ductile Iron Body - Permanent Mounting Configuration)

Rugged design and the ability to generate high frequencies and high centrifugal forces at large amplitudes, make durable DR Pneumatic External High Frequency Roller Vibrators an excellent choice for consolidation and compaction in Precast and Prestressed Concrete applications. They generate pressure waves that separate aggregate particles and reduce friction between them, to release entrapped air and increase density. The same properties also make them well suited for compaction in Refractory forms and molds.

Permanent mounting configurations are well adapted for vibration tables in concrete and refractory casting applications as well as permanently mounted material handling bins and hoppers with up to 78,000 lbs. of materials in the tapered portion of the enclosure.
  • Dual roller design produces high forces and frequencies (5,000 to 19,000 rpm max.) and large amplitudes.
  • High strength ductile iron body, with hardened steel shaft, rollers, and end plates, delivers heavy-duty performance.
  • Very low maintenance design helps make these vibrators an economical choice for heavy-duty casting applications.
CR PNEUMATIC EXTERNAL HIGH FREQUENCY ROLLER VIBRATORS (Ductile Iron Body - Portable Mounting Configuration)

With similar construction and characteristics as the DR Permanently Mounted External High Frequency Roller Vibrators, this series delivers similar output performance in terms of force, frequency, and amplitude, but with the added flexibility of a portable mounting configuration. This adds versatility for use in concrete and refractory form applications, as well as the mobility to adapt to bulk material transport applications for railcar unloading.
  • Portable mounting configuration delivers mobility for easy repositioning when casting a variety of concrete shapes in a production environment - precast forms, concrete pipe, manholes, culverts, and tunnels.
  • Portable design is also adaptable to railcar unloading applications.
  • Dual roller design produces high forces and frequencies (5,000 to 19,000 rpm max.) and large amplitudes.
  • High strength ductile iron body, with hardened steel shaft, rollers, and end plates, delivers heavy-duty performance.
  • Very low maintenance design helps make these vibrators an economical choice for heavy-duty casting applications.
SPEC THE RIGHT SOLUTION WITH AN AIR OF CONFIDENCE.
Deca Pneumatic Roller Vibrators have all the backbone needed for harsh heavy-duty applications such as concrete and refractory casting, as well as the force, frequency, and amplitude options to satisfy a wide range of dry bulk material handling applications.
