CAUTION
When adding following components of animal feed, one must pay special attention not to
allow foreign matter to fall into the tank.
It is forbidden to exceed maximum speed of power take-off shaft that is 540 rpm.
Before setting about loading the machine, one scrub all components packed in round or
square bales from strings, foil, net or other packing material.
It is forbidden to exceed maximum allowable load capacity of the feed car. In case of
installing additional added top walls that do not make the standard equipment, it is
forbidden to prepare volume of animal feed exceeding 10m
3
.
Some components that are used for preparing feed bulk may grow larger with contact
with water – for example pressed beet pulp. For that reason one must pay attention not
to exceed maximum allowable tank capacity when preparing animal feed.
Milling and mixing process may be started at rotational speed of power take-off shaft not
bigger that 200 – 300 rpm. This restriction mainly applies to mixing light and dry food
components, such as hay or straw. It is allowed to speed up when foodstuffs are initially cut
and mixed. One must remember that maximum power take-off shaft speed must not exceed
540 rpm. Foreign matter that fall into the tank will shorten life-time of cutting blades and
milling blades and they may also be the reason of morbidity rate increase. Adding all food
components as one bulk may obstruct or disenable preparing good animal feed and
contribute to overloading of worm driving unit.
4.5 COMPOUND FEED ANALYSIS
Appropriate degree of mixing and milling of foodstuffs ought to be verified each time when
adding following food compound. Operator of the feed car should take several samples of the
feed and visually determine level of homogeneity. If following samples are similar one to
another it means that the animal feed is being properly milled and mixed. Otherwise it is
necessary to continue milling and mixing before adding following feed bulk. Preparation
process may be controlled when standing on the podium but provided that special care has
been exercised when climbing on / down the podium.
If the feeding formula has been worked out, it is recommended to take notes for the first
couple of weeks of using the feed car. The notes should include the amount of particular food
component, time needed for its milling and mixing and approximate degree of humidity.
