Each 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 difficult powders (e.g. lumpy or bridge
building materials) and micropellets.
The weigh bridge is a sanitary version and is therefore suitable for quick and
easy cleaning.
Design
Twin screw feeder mounted on a 12 kg scale.
The MT12 Microfeeder is available in standard finish as well as two pharmaceutical finishes.
A variety of feeder screws allows for handling a wide range of bulk materials.
The feeding equipment is easy to dismantle. The agitator gently moves bulk
material to the throat and then into the feed screws.
A protective enclosure (plexiglass) is included to isolate the feeder from
outside influences and ensure maximum accuracy.

K-Tron Control Module (KCM) (see sheet S-070207)
The KCM combines the control module, the motor drive module and the operator
interface in one compact unit. The KCM is generally mounted near the feeder
(except in ATEX 2 GD and NEC Class 1 / Div I applications). An optional stainless
steel enclosure is available for the KCM for pharma applications.
Feeder Screws and Feed Rates
Actual feed screws will be determined by the material being fed.
Feeder screws are easily interchangeable.
