Volumetric Feeders T35

* Application
Volumetric feeding of free flowing powders and granules. Very hard to handle powders (e.g. lumpy, moist or bridge building materials) as well as fibers and flakes may need flow aid options.
The feeder can be upgraded to a loss-in-weight feeder system at any time.
* Design
Twin-shaft feeder with interchangeable feeding tools.
All parts in contact with the material being fed are stainless steel.
Feeding equipment is easy to dismantle. The horizontal agitator ently moves bulk
material to the large throat and then into the discharge screws. It is removable without tools. The horizontal agitator speed totals 20 % of the screw speed.
* Controller: (see separate data sheet)
The K2-MV-T35 uses the microprocessor based DigiDrive DC closed loop motor speed controller. The pulse width modulation eatures of the DigiDrive controller allow the motor to run efficiently at all speeds, increasing motor life and providing control accuracy to ithin ±1 rpm. The simple user friendly interface allows entry and isplay of feeder output in selectable engineering units. Alarms are rogrammable. Setpoints can be stored.

• Feed rate information
  The feed rates stated serve only as a guide. They may deviate significantly from the values given in the tables depending on the bulk material used. Accurate feed rates only after a test with the ulk material. The maximum values stated are based on a DC motor speed of 2000 rpm and a screw filling of 90%. For continuous operation it is recommended that the speed of the screw should not drop below 5 rpm.
  
• Feed rates when using AC motors
  The feed rates may here be roughly estimated through a calculation using the screw speeds. The standard speed range for a 1500 rpm AC motor is 140 to 2000 rpm. Optionally also AC motors unning at 1000 or 750 rpm are available. Screw speed range upon request.
