DE-DDW-25

Loss-in-weight-feeder

The DE-DDW-50 is a compact dosing system for volumetric and gravimetric dosing of heavy flowing powders in the lower capacity range.

Highlights

High feeding accuracy and reliability guaranteed even with difficult flowing bulk solids
Integrated agitator prevents bridging and ensures uniform screw filling level
Easy cleaning and maintenance due to easy disassembly possibility
Space saving and compact design
Flexible use in different industries and environments
Supplied fully assembled and can be quickly commissioned via the web server or the optionally available HMI

Compact powder feeder

The DE-DDW-25 dosing differential feeder is a compact device for dosing,
-especially- of powders with difficult flowing properties.

Features

Accurate dosing rates of difficult flowing powders in the lower capacity range of 1-150 dm³/h
Wide range of applications in industrial environments, pilot plants or laboratories
No complex wiring necessary due to the control box for the control and weighing electronics mounted on the unit
Change of the complete hopper incl. screws in a few simple steps
Manual or fully automatic filling due to different accessories and variants of lids
User-guided commissioning of the system even for inexperienced employees
Various Ethernet protocols enable connection to customer PLC systems and are the basis for using the integrated web server

Options

Exchange screws, -screw tubes
Vertical outlet
Hopper lid for automatic or manual filling
Hopper lid with filter bag or jet filter for venting

Technical Features of continous dosing

Dosing tools and dosing capacities

Screw type	Screw- diameter [mm]	Screw- gradient [mm]	Tube diameter outside/inside [mm]	Max. Dosing capacity [dm³/h]*
Spiral srew	15	15	24/17	1 - 150
Spiral srew	25	25	30/27	1 - 150

* The specified dosing capacities are theoretical values in volumetric operation and with a screw filling level and a motor speed of 100%. The dosing capacity can be significantly influenced by screw and gear changes. In gravimetric dosing, the dosing capacity is generally somewhat lower. The actual capacity is essentially determined by the material properties of the bulk material and must be determined individually.
