DE-DDW-25

Differential Batching Scale

The DE-DDW-25 differential dosing scale is a compact dosing system designed for volumetric and gravimetric dosing, primarily of free-flowing powders in the lower capacity range.

Highlights

High dosing accuracy and reliability are guaranteed even with difficult-to-handle bulk materials
Integrated agitator prevents bridging and ensures uniform screw fill level
Easy cleaning and maintenance thanks to simple disassembly
Space-saving and compact design
Flexible use across various industries and environments
Delivered fully assembled and can be quickly commissioned via the web server or the optionally available HMI

Technical Features of Continuous Dosing

Dosing Tools and Dosing Capacities

Screw Type	Worm diameter [mm]	Screw pitch [mm]	Pipe diameter Outer/inner [mm]	Max. dosing capacity [dm³/h]* check
Spiral screw	15	15	24/17	1 - 150
Spiral auger	25	25	30/27	1 - 150

* The specified dosing capacities are theoretical values for volumetric operation at 100% screw fill rate and 100% motor speed. The metering capacity can be significantly affected by changes in the screw and gearbox. With gravimetric metering, the metering capacity is generally slightly lower. The actual capacity is largely determined by the material properties of the bulk material and must be determined on a case-by-case basis.
