Mecanismo Dosificador Múltiple Tornillo/Agitador de Velocidades Distintas - Modelo Serie BDF

The BDFM, BDF-1 and BDF-1.5 models are designed with two agitators and a mechanically synchronized dosing screw to operate at different speeds.

General description

Model BDF-1 Dosing Mechanism

The BDFM, BDF-1 and BDF-1.5 Models, Acrison Volumetric Dosers combine two counter-rotating agitator screws at the same speed, and a dosing screw rotating at a dissimilar speed to produce positive transport of a wide range of dry solids including Those considered difficult to manage.

All other BDF series dispensers (BDFX-1.5, BDFX-1.5-2, BDF-2, BDF-2.5, BDF, BDF-4-1-3, and BDF-5) are designed with different gears for Agitators and dosing screw (s).
