by quality components and construction, Kirby Manufacturing Incorporated is the only choice when it comes to purchasing a
heavy duty Vertical Feed Mixer. The following features come standard
with each Kirby Vertical Mixer:
Efficient Auger Design – All Kirby
vertical augers are made from heavy duty, extra thick, 80,000psi tensile
strength steel plate material. This
material guaranties the owner a long and useful auger life.
The geometry of the auger flighting is engineered for minimum
power demand (HP), therefore reducing the overall wear on the equipment,
as well as, reducing the owner’s reoccurring operating costs.
Mixing Chamber – All Kirby
vertical mixing chambers are constructed from the highest of quality
materials. All tub components are fabricated from 80,000psi tensile strength
steel. The floors, walls and
doors are made extra thick to support the heavy loads.
Since Kirby standardize its tub design, all tubs are designed to meet
the demands of our largest
mixer. All stainless steel lined mixers are designed with extra thick stainless
steel to give the end-user those extra years of use that they demand
when purchasing a mixer.
Hydrostatic Drive System – The Kirby
“hydrostatic drive system” is a proven power system that offers
both simplicity in design and the robustness necessary to meet the
rigorous demands of the cattle feeding industry.
“hydrostatic drive systems”
are complimented by “two
speed” hydraulic motors that “automatically”
shift between low and high speed. This
action is driven by the mixer’s power demand.
At the start of mixing a feed batch, the motors/augers will be in
high speed. This higher speed
action ensures a quick, uniform and efficient cutting of all roughage
material. As more
ingredients are added to the mixer, the pressure in the hydraulic system
will increase. At a pre-set
pressure, the motors/augers will “automatically”
shift to low speed. This
lower speed allows the mixer to mix even the largest of loads with ease,
while still producing a thoroughly mixed TMR ration and at the same time
minimizes damage to the more fragile ingredients.
This “automatic” shifting down action also reduces the overall power
requirements of the mixer, therefore, once again reducing the owner’s
reoccurring operating costs. When
discharging the feed from mixer, the mixer will “automatically” shift to high speed when the system’s operating
pressure is below the pre-set
pressure. This higher speed
will help assist with a fast and uniform clean-out of the mixer chamber.
Proven Mechanical Drive System –
“mechanical drive system” is a robust power train that is
engineering to give the end-user years of trouble free usage.
The Kirby mechanical drive system has two configurations; one being
a direct drive and the other being a “shift-able”
two speed drive system. Either
configuration is designed to meet the rigorous demands of the cattle
feeding industry. All drive
systems are equipped with shear bolts that act as “fail
safe” devices to protect against costly drive component failures.
Running Gear - The Kirby
“running gear” on all trailer mounted mixers are design for the most
demanding of applications. All
frames are engineered to accept the weight loads that are put upon them.
Each individual component (axles, wheels, tires, etc.) is
evaluated to ensure that it meets/exceeds the loading requirement for
Accurate Feed Weighing System -
vertical mixers have the ability to be fitted a wide variety of scales
form all the industry leaders.
The design of the Kirby
weighing system utilizes “load
cells” rather that “weigh
bars” between the mixing
chamber and the transport frame. This
load cell mounting method
measures only the true
downward load created by the change in weight of the produce being
loaded into the mixer. By
design, the load cells are less sensitive to registering any of the false side
loads that are generated when a mixer is rocking back and forth during
operations. This difference
is just one of many keys to the superior accuracy of the Kirby weighing system.
