OMCO Batch Mixer
The patented OMCO batch mixing
vessel consists of a stationary cast bowl with a contoured shaped
bottom. A mixing blade is contoured to the bowl extending across
the diameter of the vessel. The rotation of the mixing blade
fluidizes the material and enacts a centrifugal force moving the
material up the side of the mixing vessel in a circular motion.
Gravitational force, assisted by deflectors when necessary, cause the
material to fold and fall into the center of the mixing blade creating a
vortex while exposing the material to shearing forces.
The Mixing blade configuration and speed are selected to
suit each application with due consideration for mixing material and
process objectives. The mixing blade itself is constructed of
steel and is lined with a ceramic tile or tungsten carbide for maximum
The OMCO Batch Mixer's drive arrangement utilizes a synchronous drive design.
This arrangement has been proven to be very reliable and durable under
many harsh environments. The D-flange motor is mounted directly on
to a slotted motor plate which bolts directly to the frame.
With our basic discharge arrangement, there is a built-in
door on the mixing bowl that opens when the cycle is complete. A
pneumatic cylinder mounted on the discharge chute operates this door
mechanism. After the door opens, the mixing blade continues to
spin and the mixed material is ejected into the discharge chute.
Once in the chute the material falls into your receiving hopper for the
next process area. The discharge chute can completely open up for
maintenance and this access is protected with a safety limit switch.
We also have our new "R" style of mixers that has a
completely new way of discharging the material. Instead of discharging
through a door in the mixing bowl and the material falling down the
discharge chute, the mixing bowl itself will completely rotate and the
material will discharge by gravity. Also, when the mixer is
inverted, the mixing blade will engage and spin to extract any remaining
All of the mixer frames on our standard OMCO batch mixers
are constructed of 2x3 tubing welded to two I-beams for wheel block
mountings. The entire frame is completely guarded to ensure
safety. The discharge chute door limit switch and door cylinder
solenoid are pre wired to a NEMA 12 junction box.
