Flow aids from OLI

When the material will not leave the silo

A bridge, a rathole, or simply too much air? First you need to know why the material stops. After that there is usually a component that gets it moving again.

Particulair supplies OLI's range of flow aids to production plants in Denmark, Poland and the rest of Europe. Pneumatic and electric vibrators, air cannons, hammers, fluidisation and vibrating silo bottoms — ATEX versions included.

The cone under a silo with air hoses, clamps and mounted equipment.

Diagnosis first, then the component. We point to what solves the problem, not to the most expensive item.

What do you see in the silo?

They look alike from the outside, but each has its own cause and its own remedy. That is why the same vibrator does not work everywhere. Pick the one that looks closest.

Narrow it down, if you like

You do not have to answer everything. Every answer sharpens the suggestion.

    Advisory. Final sizing needs a conversation, and for some materials the answer is not equipment at all, but the geometry of the hopper.

    The range

    Six ways to get the material moving

    Pneumatic ball vibrator in a blue cast housing with the air inlet on top.

    Pneumatic vibrators

    Ball, roller, turbine and piston vibrators. The workhorse of the range.

    Find the right one

    Air cannon with discharge pipe, mounted on an angled bracket.

    Air cannons

    One powerful blast of air along the wall that breaks bridges and tears firm deposits off, where vibration is not enough. The OLI PG range.

    See the product page

    A pneumatic hammer seen from the front at an angle: a ribbed aluminium housing with a solenoid valve and cable on top, bolted down on a black square plate.

    Pneumatic hammers

    One measured blow against a welded plate, where the material clings to the wall and neither air nor vibration tears it loose. The OLI PS range.

    See the product page

    Fluidisation pad with a porous face in a stainless frame.

    Fluidisation

    Pads with a porous face that lay air in under the material along the wall so it lets go. The OLI I100 and U ranges.

    See the product page

    Two vibro-aerators with a dished head and a threaded stem.

    Bin aerators

    Small air discs in the cone wall that break the bridge where it stands. The OLI VBS range.

    See the product page

    Vibro-aerator for a silo trailer, with a blue head and a discharge port.

    Equipment for silo trailers

    Unloading tankers and silo trailers, where time at the ramp is what costs.
