VIBRATION PRODUCTS

FEATURES

• Suitable for cement, lime and similar powders

DESCRIPTION

U025 and U060 Aeration Nozzles can be easily fitted on bins or silos from

outside, which makes them particularly suitable for retrofitting or in cases

where the inside of a bin or silo cannot be accessed.

FUNCTION

The plastic insert, with the sintered metal nozzle, is screwed into the steel

nipple, which has been previously welded on the outside of the bin or silo.

Then the connection with the compressed air line has to be carried out.

U025 and U060 Aeration Nozzles are used with fine powdery materials at

a working pressure of 0.2 bar (3 PSI). Decades of experience have shown

that virtually all materials can be successfully fluidised at intermittent

operation according to Pulse-Jet or Felder System.

FEATURES

• Sturdy design

• Self-cleaning

• Abrasion-resistant

• Easy to install

• For powders and granular products

DESCRIPTION

Vibrating Bin Aerator types VB, VBE, VBI and VBM combine product

aeration under operating pressure reaching 6 bar (87 PSI), with an

additional slight vibration on the silo wall (see data sheet for sizing,

positioning and number of aerators). Due to its design, damage of the silo

is impossible, even with abrasive materials. An additional backstop valve

is not required as, due to the work pressure of 2 to 6 bar (29 to 87 PSI),

no material can enter the zone beneath the elastic FDA-approved silicon

lip. OLI

®

Vibrating Bin Aerators are used for the improvement of mass

flow with powders and granular materials. Thanks to FDA-approval, the

Vibrating Bin Aerators are suitable for food-grade applications. To meet the

most demanding user requirements, a stainless steel shaft version (VBI)

is available.

FUNCTION

Compressed air is introduced into the stored material through the silicon

lip, which adheres to the inside silo wall. By varying the work pressure

within a range between 2 and 6 bar (29 to 87 PSI), the intensity of

vibration of the elastic silicon lip can be changed. Due to interval operation

and a maximum operation time of five seconds, air consumption is very

low.

SPECIFICATIONS

Working temperature:

-20 to +80° C (-4 to +176° F)

FEATURES

• Suitable for cement, lime and similar powdery materials

DESCRIPTION

Due to the semi-convex shape of the durable polymer I100 Aeration Pads,

air is given off at a wide emission angle across the entire white surface.

FUNCTION

Fluidisation equipment is used as a preventive measure. A variety of

materials will show perfect mass flow as soon as a certain amount of air is

added at regular intervals during discharging of the bin or silo. With I100

Aeration Pads, the action is gentle at an operating pressure of the pad of

0.2 bar (2.9 PSI). The air-enriched material gains the desired flowability. At

the same time, possible tendencies of the product to bridge, rat-hole, go

lumpy or deposit are prevented.

In a single row installation, I100 Aeration Pads are widely used for

materials like cement. More sophisticated applications with alternately fed

multiple rows are for example, designed for hydrated lime in storage and

dosing plants, where fluidisation is used not only during discharging of the

silo but also to keep the material in motion during longer storage periods.
