Klinkenberg’s extraction screws are individually designed and produced to the client’s specifications Klinkenberg’s extraction screws are individually designed and produced to the client’s specifications. Our experience and knowledge of the latest technology in screw feeder systems ensure that customers are properly informed about what can be achieved with this type of dosing screw. The dosing screw does what it is designed to do, under all circumstances and with every imaginable product. The dosing screws are available in completely gas-tight versions for dosing very fine or hazardous powders and granulates. This means that hazardous vapours and noxious odours remain inside the system. It can be made in stainless steel or other materials, including wear-resistant materials. Naturally, a lot of thought goes into sealing the axle pin apertures to guarantee dust-tight construction. Mass flow technology In applications where it is important to generate a mass flow, it is important that the product column above this screw gradually sinks according to the FIFO

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.

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.
