Electrical installation:
The supply cable is guided through the cable gland in
the control cabinet and connected as shown. Always
use ferrules on the cable ends and tighten the screws
securely.
Electrical diagram for the cleaner can be found in the
control cabinet.
Direction of rotation
The electrical connection must be made, so that the
direction of rotation of the drum, blower and auger in
the bottom trough is counterclockwise (seen from the
inlet end of the cleaner).
Capacity:
Maximum capacity of the cleaner for pre-cleaning of
grain is:
•
approx. 40 tons/hour for KDC4000
•
approx. 80 tons/hour for KDC8000
Generally, the capacity will depend on the required
cleaning efficiency - the smaller the load of the screens,
the better the separation of impurities.
The conveying system should therefore be designed to
allow adjustment of the material supply to the cleaner,
to obtain the desired cleaning efficiency.
General advice concerning capacity and selection
of screens:
The inner screen separates the large impurities from
the crop. The main flow of crop has to pass through
the inner screen. Selecting screen with small hole size
compared to the kernel size gives the most efficient
cleaning, but reduces capacity. Selecting screen with
large holes compared to kernel size gives capacity but
reduce cleaning efficiency. If too much crop is feed into
the cleaner, good kernels will be discharged together
with the impurities.
To reach max. capacity, it is then necessary to use
screens with large enough holes to allow the kernels to
pass through fast enough. On the outer screen small
impurities and small kernels are separated from the
crop. For pre cleaning, there is no limitation in capac
-
ity in relation to screen selection. For size separation
of kernels on the outer screen approx. 10 – 20% of the
capacity rated for pre cleaning can be obtained.
The best cleaning result is achieved with dry crops.
