Bin Aerator

Bin Aerator

An umbrella-shaped aerator that cleans the silo wall and fluidises the material at the same time, keeping powder moving through the cone without a mechanical system.

Built to Keep Powder Moving Against the Silo Wall

Cosben Engineering’s bin aerator is designed to improve material flow in silos and hoppers where powders tend to compact or stick. In bulk material handling systems, flow issues like bridging or poor discharge are common – this is where a reliable silo aerator or fluidizing pad becomes essential.
The aerator features a unique umbrella-shaped design that performs two functions at the same time. It helps clean the side walls of the silo while also fluidizing the material, ensuring smooth and uninterrupted discharge through the silo cone.
Used as a cement aeration pad or powder aeration device, it supports consistent material flow without requiring complex mechanical systems.

Key Features & Benefits

Why plant operators specify a Cosben bin aerator instead of a mechanical flow aid.

01

Improves Material Flow

Helps prevent material build-up and supports smooth discharge.

02

Dual Function Design

Cleans silo walls while fluidizing the material simultaneously.

03

Suitable for Powder Handling

Works effectively in silos, hoppers, and bulk storage systems.

04

Simple & Practical Solution

Easy to install and integrate into existing systems.
