The
M-Series, first developed in 1983, has become the
premier high speed continuous mixer available in
the market. Rugged durability, simplicity of
design and operation, and low maintenance make the
M-Series ideally suited for the tough foundry
environment.
The
M-Series has undergone many upgrades through its
life that have not only enhanced performance, but
also product longevity and safety.
The
list of available options is nearly endless,
allowing Palmer to build a machine that matches
the exact process requirements. |
The
CAM-Series was developed as a response to the
industry's need for an economical continuous mixer
that retains full functionality offered in higher
priced machines. The CAM, based on design
principles of our well known M-Series, is a low
cost, greatly simplified version of the original.
The same rugged durability has been designed into
the CAM that has been our trademark for years.
Development of the CAM allows Palmer to meet or
beat used mixer pricing in a brand new machine.
Covered by our standard one year warranty, the CAM
is an ideal choice for smaller shops, start-up
operations, or in applications where continuous
mixer use is infrequent. |

The
mixing chamber is a direct drive design that
eliminates all maintenance associated with timing
belt and gear drive systems. The mixing chamber is
made from heavy walled steel tubing that is
externally reinforced for maximum rigidity.

The
mixing chamber door features two quick release
knobs that allow for simple, easy access to the
interior of the chamber. The door is hinged at the
bottom and swings down to allow complete access to
the mixing blades and driveshaft. The hinged door
eliminates all ergonomic and mechanical problems
associated with the removal of fabricated
components from the mixer. Mixers above 300
#/minute include two chamber doors to reduce the
total weight each.
The
heavy-duty mixing driveshaft is made from high
strength ground and polished steel shafting and is
direct coupled to the primary drive motor.
The standard mixing blades are
faced with Ό" thick tungsten carbide and are
either a fixed or adjustable position blade
depending on size. Pin style (fixed angle) blades
are standard on models M50XL through M300XL.
Models M500XL and larger feature threaded blades
as standard with pin style blades as an option.
See the attached mixer specification sheet for
details.
The mixing blades are
overlapping and sized to allow a build up of
resinous material that creates the lining of the
inside of the mixing chamber. This lining provides
an optimum relationship between the end of the
blade and the interior diameter of the chamber. It
is constantly maintained by each blade as the
mixing shaft rotates. With this lining as an
intentional part of the mixing chamber, the daily
cleaning consists of only removing the build up on
the mixing blades and driveshaft. This lining
also prevents through flowing sand from constantly
abrading the mixing chamber, thus improving
chamber life.
The
mixing chamber is designed to be as rugged yet
simple as possible. The long lasting mixing
blades, close tolerance regenerative lining, and
high speed rotation provide an extremely intense
blending action with a minimum amount of cleaning
and maintenance. |
The
mixing shaft is direct driven by an oversized
three phase motor (CAM-1 - 5 HP, CAM-3 - 10 HP,
CAM-5 15 HP). The mixing chamber is made from
heavy walled structural steel and fabricated
components.

Dual mixing chamber doors feature six hand knobs
each allowing access to the interior of the
chamber from either side while maintaining door
seal. The doors are fully removable to allow
complete access to the mixing blades and
driveshaft from both sides of the chamber.
The
heavy-duty mixing driveshaft is made from high
strength ground and polished steel shafting and is
coupled directly to the primary drive shaft
eliminating couplings and alignment issues.
The
standard mixing blades are faced with Ό" thick
tungsten carbide and are fixed-position, pin style
blades.

All primary
electrical components are housed in a NEMA 12 dust
tight disconnect enclosure. All components are
thoughtfully arranged for ease of operation and
maintenance. The basis for the electrical
components specified is the heavy-duty,
long-lasting NEMA specification.
A
small enclosure is located at the operator station
and contains the control switches needed for
automatic mixer operation.
The
control system has a master safety relay with
mixing door limit switch and emergency stop
pushbuttons on both the machine cabinet and the
operator station.
There are two modes
of mixer operation:
-
"HAND" This is a
manual mode of operation with which any or all
aspects of the mixer are operated via two
position switches located on the door of the
main electrical enclosure
- "AUTO" In this
mode of operation, all aspects of the mixer
are run from a remote panel located at the
operators station.
A
single three-phase electrical service is required.
An internal 1 KVA transformer housed in the
enclosure provides the 120-volt control power.
The
pump circuitry consists of three digit pushbutton
potentiometers used in conjunction with state of
the art Pulse-Width Modulated DC Motor Controls.
The PWM regulates motor speeds to within .5% of
setpoint. The pushbutton potentiometers, mounted
on the door of the main electrical enclosure,
allow for simple, positive, pump adjustments as
compared to rotary potentiometers.
The
M-Series features as standard a thorough control
system which allows the user to easily control the
sand quality of the first and last sand. Using a
state of the art smart relay, the on and off delay
times of both the sand and resin can be easily
controlled to within one tenth of one second.
This smart relay allows for the ultimate in
flexibility and control. It features the power of
a plc (with integral display) at a fraction of the
cost.

The
control switches needed for automatic mixer
operation are located in the side of the primary
electrical enclosure nearest to the mixer
discharge. This location allows for ease of
operation while minimizing S.O. cords, flexible
conduit, and other electrical connections,
minimizing maintenance of these items. An option
is available to locate the operator controls on
the nose of the mixing chamber.

The pumping system
is fully enclosed in a separate NEMA enclosure to
protect the components from the plant environment.
The standard
pumping system consists of:
-
Two cast iron gear
pumps of wetted packing design
- Two Ό HP DC volt
gear head motors
- Two fast action
stainless steel air actuated ball valves
The DC volt gear
head motors provide consistent output RPM across
their full output range.
The pumps are
direct coupled to the drive motors to eliminate
the inaccuracy found in chain, belt, and gear
reduction couplings. The direct in-line coupling
also eliminates all side load on pump bearings and
packing extending the life of the pump.
High-torque DC
motors coupled with the large volume iron gear
pumps allow the M-Series standard pumping system
to run without the need for recirculation while
still providing instant on / instant off resin
delivery. Not only does this eliminate resin
delivery inconsistency seen in high-speed,
low-torque pumping systems, but also reduces wear
of pump components as they do not need to run
constantly.
Fast response air
actuated ball valves provide instant routing of
chemicals to the mixing chamber and prevent the
possibility of "bleed back" in the binder lines.
This in combination with the air jet system
ensures good first and last sand.

M-Series Air
Jet Controls
Click to Enlarge
An integral part of
the M-Series design is the use of a low pressure
air jet system for the introduction of chemicals
to the mixing chamber. The air assist serves two
primary purposes. The first is to keep the
chemical inlets of the mixer clear during the
mixing and purge cycles. The second is to
partially atomize the resin entering the chamber
to aid in resin dispersion and mixing.
Each jet assembly
is easily removable making calibration at the true
point of entry simple. Unlike other systems,
calibration with the M-Series is directly out of
the orifice feeding the mixing chamber, reducing
calibration error.
The air jet system
is fully adjustable via flow controls located in
the air valve enclosure. The separate NEMA 12
enclosure greatly simplifies maintenance and
reduces the potential of valve failure due to dirt
or impact. |

Spare Parts
With our background
of working in foundries we understand the need for
affordable, easy to acquire spare parts. A
fundamental in our design philosophy is to use
commercially available, standard sized and
specified parts whenever possible. Not only does
this make it easier for us to acquire parts when
we build a machine, but it also makes it easier
for you, the end user, to find replacement parts
when they are needed. We do not hide or remove
original part numbers nor do we specify odd parts
to force you to buy from us. Not only do we stock
commonly used parts so that they are available
next day if required, but also, most of the parts
that we use are also stocked at high quality
industrial supply houses nationwide. |
