Master-Batch Feeder For Powder

Master-batch Feeder for Powder (MFP)

MFP doser, also called volumetric Powder Doser, controls the volume of powder to feed masterbatch or resins accurately.

Easy operation:Enter the weight of the resins,screw back time, dosing capacity per turn and additional rate of the masterbatch, it will calculate proper P.R.M. rate automatically. The function is available to store up to 10 sets of R.P.M. Setting memory.
Flexible extension:Each feeder controls and operates individually. It is easy to add extra a feeder or change the type of screw later. A dosing and mixing system of various resins is available for your early inquiry.
Precise calculation:With the special process, the internal part of the unit has no dead corners and makes the dosing process more accurate.

REMARKS

Dosing capacity in kg/hr are tested with bulk density of masterbatch 0.4 kg/cm³ by continuing.
Dosing capacity varies in accordance with the density of granule,size of masterbatch frequency,and R.P.M.
We reserve the right to change specifications without prior notice.

Check if there has a control signal.

Check if relay is plug in and the control signal of relay can not match the specification. (Be sure the signal at the customer is DC-12V, DC-24, and AC-220V)

Check if press TIMER key already.
Check if the motor, gear, screw sets is block or not. Also check the motor wire connector, IC board and converter…etc.
No material or screw is broken.
Check if the IC board is away from high frequency area.

If still can not solve the problem. Please make sure the brand of converter then chooses a suitable converter.
Adjust converter to reduce the time.
Check if the output is at 0-10V, and the signal is connected. Wire of ＋－ is on right connection.
Check if the motor, gear, screw cylinder is block or not. Also check the motor wire connector, IC board and converter…etc.
Because the material is not smooth, the speed sometimes gets faster or slower. The solution of this problem is to use no testing hole cylinder or adjust the converter.
9. For example, if customer’s extruder is at 40 rpm and our MF is at 40 rpm. When extruder is at 20 rpm and our MF is at 20 rpm. Why will MF show 15 rpm? (EXTRUDER TYPE)

This is a linear problem.
As our MF linear is a straight line. The customer’s extruder linear is curve so our MF can not reach this extruder.
