Fluidization as solution for flow problems Fluidization of bulk materials with SIPERM aeration components as a sloution to several flow problems
Fluidization as solution for flow problems
Fluidization of bulk materials with SIPERM aeration components as a sloution to several flow problems 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. Fluidization the solution 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. You can chose between * Custom-made aeration bottoms, cones or inserts which we manufacture to your specifications * Plate material for adapting to your own systems * Standard aeration pads which can easily be retrofitted into existing systems

Fluidization insert - Siperm HP antistatic
Fluidization insert - Siperm HP antistatic
On the basis of pure polyethylene Tridelta Siperm has developed a new material with high conductivity; Siperm HP antistatic. This new, black material has the positive properties of the white material Siperm HP, the distribution of the pores is homogenous, the surface extremely smooth, it is extremely well weldable and it is officially approved to be food-safe. The surface resistivity of the new antistatic Siperm HP material is below 106 ohm and therefore it can be designated as electrically conducting. Especially for construction companies for bulk handling plants this newly developed, antistatic material may be of interest.

Two-layered porous plates with combined properties
Two-layered porous plates with combined properties
Tridelta Siperm has developed a two-layered porous material. Compared to our standard qualities, which show a homogeneous pore structure in the cross-section, the new material consists of two layers with different pore sizes. The sinter bridges which are formed between the two layers in the sintering process prevent that the layers loosen from each other when the material is cleaned with compressed air. In use the smoother side is facing the product in order to either achieve a maximum filter efficiency or – in the sphere of fluidization – to avoid the infiltration of the bulk into the fluidization unit. The product-averted side consists of a rougher, more permeable layer in order to hold the pressure drop as low as can.

Covering for compacting rollers - Siperm R
Covering for compacting rollers - Siperm R
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. Such fine-grained bulk materials can be compacted down to 20% of their bulk volume using vacuum compaction rollers made from SIPERM-materials. 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 rollerbody. This can either be done by the customer himself or by Tridelta Siperm GmbH.

Aeration Spot - Siperm R
Aeration Spot - Siperm R
Problems are often experienced when handling powdery and fined-grained bulk materials, such as flour, cement, pigments or fine plastic powders. Storage, mixing and discharge are difficult because these fine-grained powders do not flow freely. They tend to agglomerate and form bridges or tunnels around the silo outlet and, therefore, can only be removed effectively using some sort of discharge aid. A highly efficient solution to these problems are pneumatic Siperm-aeration components. They are supplied complete with all the necessary hardware (seal, washer, nut) and can also be retrofitted into existing systems. The SIPERM-R spots have a diameter of 100 mm. The pads are available as standard in sizes of 125 x 250 mm and 125 x 500 mm. Of course we also manufacture pads in special sizes.

Fluidization insert - Siperm R
Fluidization insert - Siperm R
Storage, mixing and discharge of bulk materials with average particle sizes of less than 0.1 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 out of the storage vessel. A proven solution to such problems is the fluidization of the bulk materials using custom-made aeration bottoms, cones or inserts which we manufacture to your specifications. Dry, dust-free air is injected to reduce the friction and cohesive forces of the bulk material, producing a continuous flow of material out of the vessel. Air supply pressure and velocity of air must be set at such a rate that the contents of the silo are evenly loosened. When fitting-out large silo areas with aerations units, it is advantageous to divide them into sectors which can be aerated interchangeably.
