K-PH-CL-SFS-KT20
Each COPERION K-TRON weigh feeder consists
of the components A, B, C and D.
Component A is specified here.
Application
Gravimetric feeding of free flowing to very poorly flowing powders
(e.g. lumpy, moist or bridge building materials), especially in pharma
applications.
Design
Twin-screw feeder with interchangeable feeding tools mounted on a
weigh bridge. All parts in contact with the bulk material being fed are
stainless steel. Feeding equipment is easy to dismantle. The horizontal agitator gently moves bulk material to the large throat and into the
discharge screws. The scale housing is completely enclosed.
Controller: (see separate data sheets)
The SmartConnex® control system allows individual or multi-component control. Each feeder has its own control module. Connection
between feeders, operator interface and smart I/O is via an industrial
network. A variety of protocols is available for connection to the
plant’s host system.

Feeder Screws and Feed Rates
Actual feeder screws will be determined by the material being fed.
Speed range (rpm) and the type of gear are determined by the feed rate.
Feeder screws are easily interchangeable.

Max. feed rates are based on a max. motor speed of 2000 RPM and
min. motor speed of 20 RPM.
The feed rate indications are approximate values.
The gravimetric feed rate can be calculated with the bulk density.
