Air loosening nozzles for the selective injection of compressed air into the silo. They are used for dusty and strongly cohesive bulk materials such as cement, flour, lime or salt. The nozzles support the discharge of the bulk material as a fluidizing aid and the aeration of the material during longer-term storage. In principle, this allows most dusty bulk materials to be treated successfully.
Air loosening nozzles provide for the injection of compressed air at the silo wall and are used for dusty and highly cohesive bulk materials such as cement, flour, lime or salt. In this way, they support the discharge of the bulk material and ensure that it is loosened up with air.
Our air loosening nozzles AN have a head made of sintered material which is permeable to compressed air. This head protrudes into the container and ensures distribution of air in the bulk material.
The plastic insert with the sintered metal nozzle is to be screwed into the steel sleeve welded to the silo wall (included in delivery) and connected to the air supply. Done!
The insert is used for fine powdered bulk material, the operating pressure is 0.2 bar. Practical experience has shown that, in principle, all dusty bulk materials can be successfully treated with air disintegration nozzles in intermittent operation (Pulse-Jet and Felder system).
- Support of the material flow
- Aeration of bulk material
Can be used, for example, in the food and pharmaceutical industries, on hoppers and containers. Aeration nozzles are largely maintenance-free.
Stainless steel version
For special requirements due to corrosive environments or for use in the food industry, our aeration cartridges are available in a stainless steel version (type ANI). The highly porous aeration cartridge made of 1.4404 stainless steel is food safe and can be used at operating temperatures of up to 500°C (reducing) or up to 400°C (oxidizing). Easy assembly is achieved from the outside by means of welding sockets (1.4571). ANI aeration cartridges are virtually maintenance-free in operation.
For special requirements, such as corrosive environments, use in the food industry, different dimensions or special installation conditions, our aeration plugs are also available in a wide range of special designs.
The aeration plugs can be made of 1.4404 stainless steel with different porosity grades.
- Operating temperatures up to 500°C (reducing), respectively up to 400°C (oxidizing)
- Assembly from the outside with welded sleeves (1.4571)
- Mounting from the inside with welded-on threaded sockets
- Aeration plugs are almost maintenance-free in operation
For applications where there is contact with foodstuffs and the compressed air input is not sufficient, we recommend alternatively our air loosening spots made of stainless steel or vibration aerators VBS and VBSI.
