18-1 Setting the feed rate
The feed rate is adjusted primarily by the motor speed. In addition, different feed rollers may be fitted that
deliver different rates of material per revolution. Refer to the Calibration Procedure and with the appropriate feed
rollers fitted, follow the instructions. You may have to change the feed rollers to obtain the application rate within
a sensible forward speed range which is calculated during the calibration procedure.
STANDARD 8 SECTION FEED ROLLS
Wide 8 section rollers for high rate application and large granules. There are 3 per machine supplied with
appropriate spacers – this should allow typical application rates and speeds to be selected. You can select 1,2 or
3 feed rollers depending on the flow rate of pellets required to give the application rate within the speed range.
Note. If applying other products such as small seeds optional feed roller kits are available.
WARNING
Always observe all application standards and guidelines provided by the product
manufacturer as some products may be toxic ! If unsure contact your supplier for more
18-2 Feed roller set up

the feed block in place

18-3 Feed roller configuration
1 x 8 Section Feed Rollers 2 x 8 Section Feed Rollers

When re-fitting the end plates to the feed block after changing the configuration, the end plate should be able to fit
flush with the feed block by hand, without having to pull it home with the socket head screws.
The assembled rolls and spacers should not be under compression.
NOTE.
You should be able to rotate the feed shaft with your fingers – if it feels excessively tight, check the feed
roller and spacer composition or call Stocks AG for advice.
