SETTING MICRO-GRANULATOR OUTPUT
The tables below list the gears and the position of the gearbox lever to be used to
dispense a given quantity per hectare according to the results of the output tests.
Given that agent grain size may vary from one year to another, we recommend
carrying out a test prior to sowing each time the agent is changed or at the start of the
season. This is all the more important in that an agent of the same brand may differ
from one batch to the next.
It is recommended that agents be stored in a dry, well ventilated room. Where sowing
is interrupted due to rain or misty weather, empty the micro-granulators in order to
prevent agents from clogging.

Output tests
∗
Place some agent in a hopper
∗
Set the gearbox to position “0”
∗
Place 3 containers under the 3 outlets of the selected hopper
∗
Turn a few revolutions using a small crank in order to prime the unit
∗
Empty the three containers and replace them under the outlets
∗
Turn the micro-granulator 50 revolutions using the crank supplied
∗
Weigh the samples. If they are similar, average them out. If a significant difference
is noted among the 3 outlets, service the micro-granulator again and repeat the
test to check output.
∗
Apply the following formula to determine the number of revolutions that equate to
the desired quantity per hectare.
CALCULATING THE NUMBER OF TURNS FOR THE MICRO-
GRANULATOR
Formula to be used:
225 x kg/ha desired
For 45 cm = -------------------------------- = number of revolutions required
test gr.
250 x kg/ha desired
For 45 cm = -------------------------------- = number of revolutions required
