Fine-grained bulk materials such as colouring pigments, manganese dioxide, soot, cement, coal dust, various ceramic powders, powders for the food industry, pesticides and many other materials are very difficult to handle.
They have a very large bulk volume, i.e. a very low bulk density, and produce large amounts of dust when transferred. In these cases compaction of powders is aimed at.

Solution:

Vacuum compaction rollers and suction pipes

Such fine-grained bulk materials can be compacted down to 20 % of their bulk volume using vacuum compaction rollers or suction pipes made from SIPERM® materials. A distinction is made between two processes:

Suction pipes made from SIPERM® are suitable for reducing the volume of bulk materials in bags or vessels. These pipes are dipped in the bulk material to be compacted, either during or after the filling process. By sucking the excess air, the filling volume of the bulk material in the container is significantly reduced.
Depending on application, different materials and filtration grades are used. We supply seamless or welded pipes made from stainless steel, bronze or polyethylene.

Compaction by means of vacuum compaction rollers. Vacuum compaction rollers are covered with SIPERM® R.
Compaction of the powders is produced by the interaction of mechanical pressure and vacuum.
The highly porous SIPERM® material used for covering the compaction rollers is available in sheet form and can be welded to create larger units and adapted by rolling to the radius of the roller body. This can either be done by the customer himself or by Tridelta Siperm GmbH.

Storage, mixing and discharge of bulk materials with average particle sizes of less than 0.2 mm frequently causes problems because these bulk materials do not flow freely and therefore are almost impossible to discharge.
They tend to agglomerate and form bridges and tunnels, particularly around the silo outlet, thereby obstructing the free flow of the material from the storage vessel.

Such low flowable materials include fine plastic powders, flour, pigments, soot, cement, pesticides etc. A proven solution for the problem-free handling of bulk solids with average grain sizes between 10 and 200 μm is the fluidization of the material using pneumatic aeration units made from highly porous SIPERM® materials.
