VibrationBottom–Easy toClean For safe discharge of powdery, crystalline, fatty and granular bulkmaterials fromhoppers. Hoppers are discharged complete- lywithout leaving residue. Funnel formation and bridging in the hopper are prevented. Can be used for virtually all bulk materi- als, even those that flow poorly, in the foods, plastics, chemicals and pharmaceuticals industries. Special advantages are: • Reliable discharge and even fall of the product column (mass flow) • Hygienic design: Smooth internal contours in the silo / hop- per without any changes in diameter, smooth surfaces on the exterior, resulting in easy cleaning No inaccessible cavities and exposed screw threads • Elastomer sleeve is easy to assemble and has an accurate fit • The sleeve is silicone-free, conductive and is approved as food- grade, assembly using clamping segments and pressure pieces • Screw locking by means of wedge locking washers • Shock pressure proof to 2 bar (overpressure) and vacuum- proof • Long elastic area, resulting in excellent disconnection between the fixed part of the hopper and the vibration bottom How it works: The lateral, imbalance vibrator sets the vibration bottom in horizontal, circular vibration. The vibrations are trans- mitted to the materials column via the simultaneously vibrating relieving cone inside the vibration bottom. This sets the bulk materials inmotion and the level drops evenly without resulting in funnel flow or bridging. The bulk materials reach the outlet safely through the annular gap. Vibration intensity can be ad- justed at the imbalance vibrator and depends onwhat materials are being discharged and the required discharge rate. AZO GmbH + Co.
