With OR-series Roller Vibrators vibration is generated by the movement of rollers inside an eccentric guide. OR generate low amplitude and high frequency vibration. Among others, they are suitable for concrete compacting tables, foundry moulds and hopper emptying due to higher force generated than by ball-type S-series vibrators.
The OR-series, which comes with a black aluminium casing and brass cover, is available in four different sizes.
Operating with oiled air at 2 to 6 bar (29 ~ 87 PSI), the OR-series is suitable for application in explosive environments (ATEX EX II 2DG cT(x)). Operating noise reaches 90 dB(A).
I100 Aerator Pads are a low-cost solution which ensures trouble-free material flow from silos, bins or hoppers with a variety of powdery materials. They can be easily mounted and retrofitted in existing plants.
Due to the semi-convex shape of the durable polymer pad, air is given off with a wide emission angle across the entire white filter surface.
Low pressure aeration or fluidisation prevents rat-holing, bridging, segregation or material residues at the bottom of the silo cone.
I100 Aerator Pads excel through a lightweight, yet robust and reliable engineering polymer casing and filter design. In a single row installation, they are widely used for materials such as cement and similar materials. More sophisticated applications with alternately fed multiple rows can be used for lime storage and dosing plants in which fluidisation is used not only during discharging of the silo but also to keep the material in motion during extended periods of storage.
A rectangular, external mounting kit is available for easily fitting or retrofitting batching plants.
Operating pressure amounts to 0.2 bar (3 PSI).
Appropriate arrangements have to be made to exhaust excess air containing entrained dust at the top of the bin/silo.
For food-grade application choose VB-series (Vibro-Aerators).
