DE-DDW-50

Loss-in-weight-feeder

The DE-DDW-50 is a ultra compact dosing system for volumetric and gravimetric dosing of bulk solids.

Highlights

Ultra-compact dosing system for volumetric and and gravimetric dosing of bulk materials
Control electronics completely installed in the housing and ready wired, or for control cabinet installation
Easily dismountable screws and top hopper for adjustment of the dosing capacity
Scale housing in trapezoidal shape for space-saving combination of the devices for circular installation
All connections designed as plug-in connections
System preset and can be put into operation without electrotechnical knowledge

Ultra compact dosing system

The Loss-in-Weight Feeder DE-DDW-50 is a compact device for dosing of well flowing bulk solids that do not require activation above the dosing screw.

Dosing tools and dosing capacities

Screw type	Screw- diameter [mm]	Srew- gradient [mm]	Tube diameter outside/inside [mm]	Max. Dosing capacity [dm³/h]*
Spiral srew	24	35	50/46	2 - 250
Spiral srew	28	35	50/46
Spiral srew	33	35	50/46

* 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.
