Abstract :
The crushing of the raw material input for
animal feed powder is carried out by a crusher machine
with a rotary speed which can crush the particles into
smaller pieces. Hammer mill is a crushing machine for
changing the input of animal feed particles into smaller
particles or powder. One part of the hammer mill machine
in crushing particles of raw materials is the hammer mill
blade, each hammer mill blade shape must be different in
the resulting the particle size results. The purpose of this
research is to make a prediction model of the particle size
seen by the hammer mill blade shape. The particle size
prediction model uses the Discrete Element Method
(DEM) with Rocky DEM software, which is compared
with the prototype results in the field as simulation
validation. The smaller the particle size for animal feed,
the better the digestion of the animal, but the larger the
particle size of animal feed, the more difficult it is for
livestock to digest their food and even damage their
digestive system. Based on the results of DEM, the particle
size resulting from the crushing process of organic waste
from coffee skin is 0.26 mm, coconut shells is 0.30 mm and
oil palms is 0.30 mm. The simulation results are similar to
the results of the collision of the prototype in the field,
which is less than 0.5 mm through the screening process
by the screening section.
