| : : What
is the reason of irregular wear of die? |
|
|
| >
Reason: |
> Solution: |
- Bad distribution of the material
- The mixture leans to getting out sideways
from the compression area
- Use of a new die with already worn rolls
- The die has a too high thickness
|
- The die may have a too high thickness
- Changement of the die is required
- The inclination of the deflectors is to be
corrected
- Use corrugated closed roll shells
- Use new dies and roll shells or possibly
dies and roll shells worn in the same way
- Reconsider the thickness of the die
|
| : : What
is the reason of too early breakdown? |
|
|
| >
Reason: |
> Solution: |
- Presence of foreign matters in the die
- The die has a too low thickness
- The housing of the die is worn out
- Breakdown of the clamping screws
- Frequent stoppages of the die
|
- The control system and the system of
removal of foreign matters while pelleting
must be improved
- Thicker dies with counter drilled holes are to be used
- The wear ring and/or the stiffening flange
are to be replaced
- The clamping screws are to be replaced
- The conditioning temperature is to be controlled
|
| : : Why
the die wears too fast? |
|
|
| >
Reason: |
> Solution: |
- The material contains sand
- Conditioning temperature
- Too rough milling
- The diameter of the pellet is too small
- The rolls are too far away from the die
|
- The cleaning methods of the raw material
require to be improved
- Optimise the conditioning
- The suitable thickness of the die should be chosen
- Add grease or additives to the mixture
- Finer milling is required
- Use the largest possible diameter of the pellet in line with
the product
- The rolls are to be adjusted
|
| : : Why
the holes of the die are clogging? |
|
|
| >
Reason: |
> Solution: |
- The rolls are too close to the die
- The die has a too high thickness
- After the work the die has not been
well cleaned with sliding material,
such as maize and oat
|
- The rolls are to be adjusted
- Change the thickness of the die
- After the end of the work fill the holes of
the die with a neutral product, such as
maize and oat
|
| : : Why
a used die does not produce? |
|
|
| >
Reason: |
> Solution: |
- The rolls are adjusted badly
- The die is clogged
|
- The rolls are to be adjusted
- To clear the die, you should try:
- to put in manually unbroken maize (through the doorlet of
the conveyor)
- to immerge the die into hot oil as last solution to drill
the pellets with a drill
