Efficient screening of difficult-to-screen bulk materials

Task Screening is an important step in the processing of bulk materials. With the BIVITEC, Binder+Co starts where conventional vibratory screens become inefficient and less economical. Difficult products, such as damp, stalky and leafy materials or matted substances block the screen openings of conventional vibratory screens, thus making efficient screening impossible. BIVITEC provides a simple solution to these challenging demands: with the help of resonance, a driving mechanism provides two vibratory movements in which the flexible polyurethane mats are expanded and compressed in turns, and...

Solution/ Operation To ensure efficient screening, much higher acceleration values than usual have to be transmitted to the screening material in the case of difficult-to-screen materials. With this in mind, Binder+Co has developed a solution which is as simple as it is efficient. BIVITEC special screening machines work with a double vibration principle from one drive mechanism. One drive mechanism provides two vibratory movements with the help of resonance. Every second cross brace of the BIVITEC screening machine is rigidly connected to the screen box (oscillating mass 1) and carries out the...

Screen deck By means of the dynamically actuated screen mats and the basic vibration, for each screen deck only the right amount of energy is transmitted to the charging material to ensure that the screening material is broken up and the screen panels are kept unclogged. The simple and well-proven drive system via e-motor ensures low maintenance costs. The screwless fastening system of the BIVITEC screen mats provide for an absolutely smooth screen deck surface, thus counteracting material deposits, or caking, which occurs more often in other fastening systems where screws and strips are used....

Red BIVITEC screen panels are the standard panels and used with all common cut points. Blue BIVITEC screen panels are softer than the red standard panels and suitable for screening abrasive materials (glass cullet). Turquoise BIVITEC screen panels are of lower thickness and used for screening fines. Yellow BIVITEC screen panels are characterised by their resistance to bases and acids, and are primarily used for screening artificial fertilisers. Green BIVITEC screen panels are resistant to microbes and thus ideal for screening compost. Binder+Co precision woven mats are used for finest screening...

Binder+Co’s original screen mats for BIVITEC screening machines are characterised by long service life and easy assembly and dismantling. To yield optimum screening results, individual screen mats are used for each relevant task. The ox-horn side-sealing system developed by Binder+Co prevents discharge of outsize material into the screen underflow and also wear and tear between the screen panels and the sides of the screen. Hole widths Punched holes Long, round and square-shaped holes and precision woven fabric mats acidic/ alkaline, abrasive charging material (e.g. cullet), removal of finest...

The Banana BIVITEC provides an ideal solution for the classification of difficult-to-screen materials with high fine-grain material content in the material feed and also for implementing two grain-size separations on one single screen deck. It combines the advantages of banana screens with BIVITEC screening. • The constant curvature radius prevents erratic changeovers when going from steep to flatter screening inclinations. • High material speeds on the screen deck and relatively low layer heights on the output side bring about considerably higher specific throughput rates. • Markedly lower material...
