The transitube –ZFP includes a flat bottom hopper with a spezial rotor which holds rigif or flexible paddles. The central hub is rotating while emptying the hopper and the paddles have a variable geometry, according to the resistance of the material.
When the resistance flows freely, its resistance keeps the paddles around the central hub. If a bridging (vault) appears, the paddles spread to break it. Then the material flows easily and is evacuated by the extracting screw, which is located in the lower part of the hopper.
The transitube –ZFP allows to meter continuously with a high accuracy – 0.5 to 3% depending on the material.
The transitube –ZFP allows to handle and convey bad flowing materials with a range of output from 0 to 10 m3/h by using a transitube –mechanical feeder.
The transitube –ZFP can be intregradet in a transitube –dosing/blending unit (carrousel), volumetric or gravimetric.
