Our standard 3000 lbs four-way forklift
removable hopper is ideal for shops that do not require large sand
silos or do not have the head room for them. These hoppers are
designed to hold a full bulk sack of sand to eliminate the handling
of small sand sacks. Available with hopper stand for ease of
installation. |
 |
|
Powder Feeder |
This flexible sided volumetric
powder feeder is used to add powder materials to the mixing
chamber. |
 |

style bearing mounted beneath the motor head plate for the primary
swivel and allows for 270 degrees of rotation. This option is
available on 300 lbs/minute and larger machines. |
 |
|
Over Arm Swivel |
This option provides for a slewing ring
style bearing mounted above the mixing chamber and allows for 270
degrees of rotation. The greatest advantage of the over arm swivel
is the total clearance available beneath the mixing chamber for
operators, conveyors, skids, etc. This option is available on 300
lbs/minute and larger machines. |

|
**NEW**
THE CUBE
|
This new option allows the user to move
the mixer easily using a forklift or move and use the mixer while
hanging from a crane. Ideal for foundries that make large molds that
require specialty facing sands or where mobile operation is a
requirement. This unit is ideal for a demo machine for resin
companies and other foundry consumable suppliers. |
 |
|
Standard Manual Articulation |
This option provides heavy-duty,
double-pivot base and arm assembly that allows the mixer to dispense
sand over a large area. Movement of the primary arm is manually
powered. A conveyor belt in the primary arm delivers sand from the
receiver at the center of the base to the inlet of the mixing
chamber. |
 |
|
SM Style Articulation |
This option is similar to standard
manual articulation with the exception that this unit rotates about
the fixed base and extends in and out from the arm (Left, Right, In,
Out Controls). The SM Arm rotates around a fixed base and the mixing
chamber strokes in and out to affect the discharge distance. The
moving appendage that the chamber is mounted to contains a belt
conveyor for the delivery of sand to the chamber regardless of
chamber position.
This option is standard with manual
movement but both movement points can be hydraulically powered. The
significant advantage of this style of arm over the standard powered
articulated arm is the ease of tracing a square or rectangular
pattern with a joystick. Positional sensors are available for lead
through programming PLC molding systems.
|
 |
|
Mobile Mixing System |
All Palmer M-Series mixers can be
outfitted onto our line of Mobile Mixing Chassis. This option is
ideal for foundries that produce extremely large molds that are not
easily moved after molding or for jobs that require a great deal of
setup time on the floor. The included link takes you to see detailed
Mobile Mixing System specifications. |
|
|
Powered
Primary Articulation |
This option utilizes a high torque
electro-mechanical system coupled with a #160 chain and sprocket to power the
rotation of the primary articulated arm. A left/right joystick
control located in the operator control panel initiates the movement
of the primary arm. |
 |
|
Powered Secondary Articulation |
This option utilizes a high torque
electro-mechanical system coupled with a #120 chain and sprocket to power the
rotation of the primary arm. The rotating sprocket is bolted onto
the standard high load slewing ring for years of maintenance free
operation. A left/right joystick control located in the operator
control panel controls the movement of the mixing chamber.
|
 |
|
Dual Sand Slidegates |
This option allows the operator to
choose from two different sands on a core-by-core or mold-by-mold
basis. A selector switch at the operator control panel determines
which sand is introduced into the mixing chamber. Each slidegate is
independent from the other, allowing different sand volumes for each
sand. Separate pump controls allow the pumping system to
automatically change resin percentage setpoints when a sand change
is made. This automatic switching allows the change in sand to be
made while the mixer is in operation. |
 |
|
Dual Sand/Blend Slidegates |
This option utilizes four air-actuated
slidegates to provide the mixer operator with a choice of 100% Sand
"A," 100% Sand "B", or a blend of both sands (Eg – Silica / Zircon /
50-50 Blend). A three-position switch, located in the operator
control panel, allows the operator to change sand selection (i.e.
from facing to backing sand) while the mixer is in operation. This
option includes three pump setpoints, one for each sand selection.
The change in pump settings is instantly effected when a change in
sand is made. |
 |
|
Dual Flow Slidegate |
(High / Low Flow) – This option utilizes
two slide gates which are used to meter sand into the mixing chamber
at different flow rates. The upper cylinder turns the sand flow on
and off. The lower cylinder has two fixed orifices for metering of
sand. The system comes with dual resin levels. This option is ideal
for shops that use the same mixer for molding and core making. The
flow can be reduced for small core boxes or increased for larger
mold boxes. |
 |
|
Remote Electric and Pump Enclosures |
This option is applicable on the M50
through M200 mixers. With a standard configuration, the pump and
electrical enclosures are attached directly behind the mixing
chamber base. With remote pumps, they are mounted on a stand remote
of the mixer for installation against a wall, on a remote mezzanine,
or any other configuration required. |
|
|
Custom Height and Reach |
Although Palmer bases its designs on
standard machines, we can easily modify a standard machine to fit
your application’s needs. Most of our designs are easily modified to
custom heights and reaches, simply contact us with your needs.
|
 |
|
Polyethylene Swivel |
This option is a low cost version of a
swivel mixer. It is used primarily for mixers that are infrequently
rotated. An example would be swiveling a mixer located over a core
machine hopper for cleaning. Two steel plates sandwich a ½” thick
sheet of polyethylene which acts as the bearing surface. The mixing
chamber is held in place with a castellated nut. |
 |
|
Skid Mounted Mixer |
All M-Series up to 300 pounds per minute
can be rigidly mounted to either a forklift or wheeled skid. The
photo shows both options in the same skid. |
 |
|
Integral Jug Rack |
For machines utilizing the standard
electrical and pumping enclosure back plate, an integral resin jug
storage rack can be installed. |

in the sand receiver or delivery system. When the sensor is
uncovered, an alarm is sounded indicating that there is a sand
delivery problem. |
|
|
Low Sand Interlock |
This option provides a proximity sensor
in the sand receiver or delivery system. When the sensor is
uncovered, an alarm is sounded indicating that there is a sand
delivery problem. An additional relay will cause the mixer to stop
mixing and enter its purge/shutdown cycle. |
|
|
PLC Control System |
Our standard mixer control system is a
PLC / HMI is AB Micrologix 1400 with a 6” C-More Color Touch Screen.
For a more advanced system, the SLC 5XX Series of PLC’s are used.
Call us with your specific needs. |
 |
|
Radio Remote Control Mixer |
 All
functions of a standard mixer control panel can easily be replicated
through the use of radio remote control. Ideal for filling of large
or deep flasks where operator safety is of utmost importance.
|
 |
|
Dual Speed Sand Delivery Belt |
Similar to dual sand flow on small
mixers, dual speed belts allow for varying sand flow from
articulated mixers. The user can switch easily between high and low
flow as dictated by the process. Ideal for shops using the same
machine to produce cores and molds or when the user needs slower
fill for facing sand, small cores, etc. A two speed variable speed
drive is used to control the belt drive motor speed. |
 |
|
Hopper Auto-Fill System |
Palmer Mfg. has expanded its
capabilities to provide you with nearly any storage systems
including silos, hoppers, auto-fill control systems for belts,
elevators, and even pneumatic transporters. Please call us with your
specific needs. |
 |
|
Resin Auto-Fill System |
The Palmer Resin Auto-Fill System is
used for controlling
bulk transfer of resin from primary storage
tanks to day tanks. The base system is set up to control liquid
levels of two independent day tanks. Two high spec proximity sensors
per day tank are mounted to a sight glass directly on the front of
the day tank. The sight glass is generally a piece of clear plastic
or rubber tubing that is compatible with the liquids contained
approximately 5/8” in diameter. When the low level sensor is clear
of material (none present), a control relay in the primary
electrical engages and sends a 120v control signal to the pumping
system of your choice (customer supplied) to start the pumps. When
the upper sensor is satisfied, the 120v signal is discontinued. No
liquid contact ensures that the sensors stay clean and unaffected by
the chemicals unlike others systems that use immersion sensoring
techniques.

|
Shear Sensitive Epoxy
Systems |
This upgrade consists of all required
components for use with the shear sensitive epoxy system or comparable resin system. It
includes a stainless steel pump one and ball valve as well as a
continuous cavity, non-shearing pump 2 and pneumatic pinch valve
set. Note that this system is set up for recirculation of liquid
components. |
 |
|
2nd Coreactant Pump |
This option works well for production
floors that require two different mold set-up rates with a binder
system that requires different activators for different set-up
speeds. This option is commonly used with ester-cured phenolics,
sodium silicates, and other binder systems where the amount of
activator does not affect strip time as much as the chemical
composition. |
 |
|
2nd Acid Pump |
|
 |
Magnetically Coupled Pumps
Standard |
This option replaces the standard system
pumps with magnetically coupled, micro gear pumps. The pumps are DC
driven, identical to the standard pump, but they operate in a
recirculating manner. The magnetic coupling provides seal-less
operation, which eliminates any maintenance associated with pump
shaft seal replacement. Also included with this option are
recirculating diverter valves for each pump. |
 |
|
Mass Flow Pumping System |
The
Mass-Flow Pumping System couples the high accuracy of self
calibrating flow meters with the benefits of a totally sealed
pumping system. These items, in conjunction with the PLC control
system, variable speed motor controls, and positive displacement magnetically
coupled external gear pumps, will accurately meter in the desired
amount of material to the sand mixing chamber. This system has
multiple output levels – each with a visual and audible high and low flow
alarm that is set at a percentage of setpoint. A four-position
switch for remote mounting is included. The output of each chemical
pump is displayed on the operator interface screen. Both displays will be read to the
desired engineering units. The operator interface will be mounted in
the main enclosures (unless otherwise specified). The Coriolis Mass
Flowmeters are the most precise meters available. They eliminate the
gear clogging encountered with volumetric meters. These design features focus on maximizing reliability
and durability and minimizing vulnerability to measurement noise.
These meters use thicker tube walls to eliminate mechanical fatigue
due to sensor wear and stress due to vibration. All input and output
signals are scanned and updated ten times per second. The Mass Flow
Pumping Systems maintain consistent flow if the chemical viscosity
changes when minor kinking of lines occurs. |
 |
|
Trial Pumping System |
This option is ideal for foundries that
regularly perform trials or switch binder systems. The standard
pumping system pictured is easily interchangeable and upgradeable.
