New feed facility
CONSTRUCTION TIPS
Equipment selection must include maintenance considerations
by Fred Fairchild

The most important thing to consider when constructing
a new facility or addition is selecting the right processing equipment. The contractor usually supplies the needed
equipment, but a thorough understanding of the products to
be made initially or later in the facility must be the guide to
selecting the correct equipment.
Many times, the owner will designate a particular brand or
model of equipment they want in the plant. Examples of this
ZRXOGEHDVNLQJIRUDVSHFL¿FEUDQGRISHOOHWLQJRUJULQGLQJ
equipment. There are no U.S. equipment companies that can
R൵HUDFRPSOHWHHTXLSPHQWSDFNDJHIRUDFRPSOHWHIHHGPLOO
resulting in more than one brand of equipment for the whole
process. There are some international companies, such as
Bühler and others, that can supply all the equipment required.
Maintenance begins at the point the equipment is chosen.
Each piece of equipment requires space around it to be able to
properly maintain it. The facility design must include access
to originally install or place each piece of equipment. Consideration in the facility design not only needs to allow for initial
placement, but also a plan to remove parts of the equipment
that may need to be removed and set aside when performing
maintenance on a machine. This might include space for removing a cover or equipment parts and set them aside to work
on interior parts of the machine.

and replacing screen decks on screening equipment. Another
example would be being able to remove or replace the mixing shaft in a mixer or exchange a complete mixer. In many
cases, the scale hopper and gate above the mixer must have a
way and room to set it aside to access the mixer. This can be
a major project. Another way to solve this problem would be
to design the mixer location so the mixer might be removed
longways, without disturbing the scale system.
Other things to consider in original installation include allowing room for access doors, such as room to allow the pellet
mill door to be fully opened for die changes and adjustment
access. Room should also be provided so that the conditioner
60

and feeder above the pellet mill can be accessed and even exchanged if needed.
Always allow room to access and work on conveying equipment. Never install a bucket elevator next to a wall where removing the boot or head shafts or pulleys cannot be removed
from both sides of the elevator. Always allow space to remove
shafts, bearings, gear reducers, motors and drive components
from any equipment. Good maintenance requires good access
to each piece of equipment. Money spent in good design will
pay dividends in maintaining the facility.
A consideration in the selection of equipment is, when possible, to try to use a single brand of motors, gear reducers and
other common parts to simplify maintenance and reduce the
amount of parts needed For drives with varying horsepower
but identical output speeds, use the same size of sheaves (pulleys), and v-belts may be used for all the drives. If the needed
output speed is the same, v-belt drives with added grooves and
belts can be used as the horsepower increases. A possible application for this might be the drives on screw feeders feeding
above a batching scale.
Drives with v-belt drives require regular preventive maintenance to make sure the belts are tensioned properly to avoid
slipping. Properly installed safety devices should detect changes in speed and warn. An alternative to a v-belt drive is a newer
type of gear reducer, such as a Dodge MTA (Motorized Torque
Arm) reducer, which is available with a wide range of internal
gearing ratios for numerous output speeds. Using this type of
gear reducer, the moto is directly coupled to the reducer, which
eliminates the use of a v-belt drive. We used this type of dive
on our bucket elevators for the O.H. Kruse Feed Technology
Center at Kansas State University.
COMPLETING THE PROJECT
The next step, known as "substantial completion," is when the

the project and making the product(s) for which the facility is
designed. It does not mean the project is complete as there are
