by the foregoing recommendations in order to make operator safety a reality.
Continuous Loss-in-Weight Blenders Chapter 1: Safety 8
1-3 Responsibility
These machines are constructed for maximum operator safety when used under standard
operating conditions and when recommended instructions are followed in the maintenance
and operation of the machine.
All personnel engaged in the use of the machine should become familiar with its operation as
described in this manual.
Proper operation of the machine promotes safety for the operator and all workers in its
vicinity.
Each individual must take responsibility for observing the prescribed safety rules as outlined.
All warning and danger signs must be observed and obeyed. All actual or potential danger
areas must be reported to your immediate supervisor.
General Responsibility
No matter who you are, safety is important. Owners, operators and maintenance personnel
must realize that safety is always a vital part of their jobs.
If your main concern is loss of productivity, remember that production is always affected in a
negative way following an accident. The following are some of the ways that accidents can
affect your production:
• Loss of a skilled operator (temporarily or permanently)
• Breakdown of shop morale
• Costly damage to equipment
• Downtime
An effective safety program is responsible and economically sound.
Organize a safety committee or group, and hold regular meetings. Promote this group from
the management level. Through this group, the safety program can be continually reviewed,
maintained, and improved. Keep minutes or a record of the meetings.
Hold daily equipment inspections in addition to regular maintenance checks. You will keep
your equipment safe for production and exhibit your commitment to safety.
Please read and use this manual as a guide to equipment safety. This manual contains safety
warnings throughout, specific to each function and point of operation.
Continuous Loss-in-Weight Blenders Chapter 1: Safety 9
Operator Responsibility
The operator’s responsibility does not end with efficient production. The operator usually has
the most daily contact with the equipment and intimately knows its capabilities and
limitations.
Plant and personnel safety is sometimes forgotten in the desire to meet incentive rates, or
through a casual attitude toward machinery formed over a period of months or years. Your
employer probably has established a set of safety rules in your workplace. Those rules, this
manual, or any other safety information will not keep you from being injured while operating
your equipment.
Learn and always use safe operation. Cooperate with co-workers to promote safe practices.
Immediately report any potentially dangerous situation to your supervisor or appropriate
person.
REMEMBER:
• NEVER place your hands or any part of your body in any dangerous location.
• NEVER operate, service, or adjust the blender without appropriate training and first
reading and understanding this manual.
• NEVER try to pull material out of the blender with your hands while it is running!
• Before you start the blender check the following:
o Remove all tools from the unit;
o Be sure no objects (tools, nuts, bolts, clamps, bars) are laying in the
metering or mixing area;
• If your blender has been inoperative or unattended, check all settings before starting
the unit.
• At the beginning of your shift and after breaks, verify that the controls and other
auxiliary equipment are functioning properly.
• Keep all safety guards in place and in good repair. NEVER attempt to bypass, modify,
or remove safety guards. Such alteration is not only unsafe, but will void the warranty
on your equipment.
• When changing control settings to perform a different mode of operation, be sure
selector switches are correctly positioned. Locking selector switches should only be
adjusted by authorized personnel and the keys removed after setting.
• Report the following occurrences IMMEDIATELY:
o unsafe operation or condition
o unusual blender action
o leakage
o improper maintenance
• NEVER stand or sit where you could slip or stumble into the blender while working
on it.
• DO NOT wear loose clothing or jewelry, which can be caught while working on a
blender. In addition, cover or tie back long hair.
Continuous Loss-in-Weight Blenders Chapter 1: Safety 10
• Clean the blender and surrounding area DAILY, and inspect the machine for loose,
missing or broken parts.
• Shut off power to the blender when it is not in use. Turn the switch to the OFF
position, or unplug it from the power source.
Maintenance Responsibility
Proper maintenance is essential to safety. If you are a maintenance worker, you must make
safety a priority to effectively repair and maintain equipment.
Before removing, adjusting, or replacing parts on a machine, remember to turn off all electric
supplies and all accessory equipment at the machine, and disconnect and lockout electrical
power. Attach warning tags to the disconnect switch.
When you need to perform maintenance or repair work on a blender above floor level, use a
solid platform or a hydraulic elevator. If there is a permanently installed catwalk around your
blender, use it. The work platform should have secure footing and a place for tools and parts.
DO NOT climb on unit, machines, or work from ladders.
If you need to repair a large component, use appropriate handling equipment. Before you use
handling equipment (portable “A” frames, electric boom trucks, fork trucks, overhead cranes)
be sure the load does not exceed the capacity of the handling equipment or cause it to become
unstable.
Carefully test the condition of lifting cables, chains, ropes, slings, and hooks before using
them to lift a load.
Be sure that all non-current carrying parts are correctly connected to earth ground with an
electrical conductor that complies with current codes. Install in accordance with national and
local codes.
When you have completed the repair or maintenance procedure, check your work and remove
your tools, rigging, and handling equipment.
Do not restore power to the blender until all persons are clear of the area. DO NOT start and
run the unit until you are sure all parts are functioning correctly.
BEFORE you turn the blender over to the operator for production, verify all enclosure
panels, guards and safety devices are in place and functioning properly.
Reporting a Safety Defect
If you believe that your equipment has a defect that could cause injury, you should
immediately discontinue its use and inform the manufacturer.
The principle factors that can result in injury are failure to follow proper operating procedures
(i.e. lockout/tagout), or failure to maintain a clean and safe working environment.

Blender System Component Description
This section describes the various components of the continuous blending system. The
continuous blending system is made up of the following components (See Figure 2 below):
• Ingredient supply/re-fill hoppers
• Ingredient weigh hoppers
• Ingredient metering auger assemblies
• Cascade material chute
• Lower mass flow weigh hopper
• Control panel
• Motor drive panel
• OPTIONAL “Quick color change” kit
Figure 2: Continuous Blender Assembly
Ingredient Supply/Re-fill Hoppers
The ingredient supply/re-fill hoppers are located on top of the blender frame. Their purpose is
to provide a supply of material to the individual ingredient weigh hoppers on demand. The
hoppers are equipped with an air-operated discharge valve that is opened by the PLC when a
respective weigh hopper needs a re-fill of material. These hoppers are sized to handle the
percentage requirements of the ingredients. Optional level sensors which might exist in these
Continuous Loss-in-Weight Blenders Chapter 2: Functional Description 14
hoppers are not controlled nor read by the blender. Their existence is solely for the use of a
low level alarm to be wired into a separate controller. These would not be present on a
standard blender.
The hoppers may be equipped with a polycarbonate sight glass. This is mounted in the upper
cone section of the hopper. This is useful for a quick reference of the material level in each
hopper.
The supply/re-fill hoppers should be vented to the atmosphere through the louver located on
the lid of each hopper. This louver is required to prevent the loading system from creating a
vacuum in the hopper, which would prevent material from flowing out properly. This
situation could be caused by a leaking discharge seal on the vacuum receiver.
Ingredient Weigh Hoppers
Each ingredient weigh hopper assembly consists of a conical mass flow weigh hopper, a
precision load cell and a discharge tube disc seal. A mass flow weigh hopper is a steep
degree conical hopper with vertical side walls with a discharge tube on the bottom. Each
weigh hopper is sized to the blender ingredient metering requirements. This assembly is
responsible for weighing the material ingredients as they are metered out by the metering
auger assemblies located below each weigh hopper. The manufacturer believes this is the
best way to weigh free flowing pelletized materials. This design allows the hopper to weigh
only the material and nothing else, unlike other systems that weigh the heavy auger
assemblies. This design eliminates extra variables, such as auger drive vibrations, etc. from
the weighing system and increases the load cell resolution. Each weigh hopper will be
refilled periodically as material reaches the preprogrammed low weight setpoint for that
hopper. Clear hopper side walls or sight glasses are provided on each on the weigh hoppers
to allow the operator to monitor the levels.
Continuous Loss-in-Weight Blenders Chapter 2: Functional Description 15
Ingredient Metering/Transport Auger Assemblies
Each metering auger assembly consists of a:
• Cast aluminum motor mount
• Cast aluminum feeder body
• Aluminum feeder tube
• Gearbox
• Inverter-duty AC drive motor
• Machined metering auger
The metering auger assembly accurately meters the material from the ingredient weigh
hopper at the calculated rate.
The mass flow weigh hopper design allows more range of the load cell to be used for actually
weighing the material and eliminates dynamic drive movement and vibrations from affecting
the load cell readings.
Figure 3: Metering Auger Components
Cascade Material Chute
The cascade material chute is a rectangular conduit in which all the metering augers
discharge. The materials are cascaded together and directed vertically down into the lower
mass flow weigh hopper. A clean out door is provided on the chute above the augers, so that
any dust can be blown out if it has collected.
Continuous Loss-in-Weight Blenders Chapter 2: Functional Description 16
Lower Mass Flow Weigh Hopper Assembly
The lower mass flow weigh hopper, otherwise known as the weighed common hopper, is
used to determine the actual processing rate of the processing machine so that the blender can
be slaved in to run at the learned rate. The hopper is constructed of spun aluminum and is of
the mass flow type (See the glossary in the Appendix). It is supported by a load cell, and will
carry a weight of material depending on how much is flowing into the hopper from the
metering augers, and how much is flowing out of the hopper, dictated by the processing rate
of the processing machine.
The computer uses the mass flow hopper flow rate (the differential rate), along with the
known total rate from the weight loss feeders to determine the actual processing rate of the
processing machine. The blender output rate is then adjusted to match the learned processing
rate. This method of operation provides very accurate slave in of the blender to the
processing rate, and eliminates the need for a mixing hopper.
The lower common weigh hopper is also equipped with a high level proximity level sensor to
allow manually adjusted volumetric operation of the blender in the event of computer failure.
Figure 4: Weigh Hopper Assembly
Note: The lower or common mass flow weigh hopper uses the change in weight over
time, of material contained in the hopper over time to calculate it’s discharge
rate (differential rate). This learned discharge rate is then summed with the
known total metering rates of the blender feeders to learn the actual processing
rate of the processing machine. The blender output rate is then adjusted to
match the learned processing rate, eliminating the need for a blender mixer.
“Fixed Rate” mode
The lower mass flow weigh hopper may be replaced by a collection hopper with “high” and “low “
level switches on higher capacity blenders. This configuration controls the blending s ystem rate
based on material level
Continuous Loss-in-Weight Blenders Chapter 2: Functional Description 17
rather than material weight.
PLC Control Panel
The PLC control panel may be mounted on the side of the blender frame, or remote mounted
near the blender. It uses an Allen-Bradley SLC 5/04 programmable controller with standard
24 vdc input output cards. This design provides excellent blender performance along with
easily replaceable off-the-shelf parts in case of any electronic component failure.
Touch Screen Interface
The PanelView 600 color touch screen display can be mounted up to 50 feet (15 m) from the
PLC control panel. It is very user friendly after installation and setup, simply enter in the
proper recipe and start the blender.
If it is desired to have a local display and control of the blender at the operator station, an
optional PanelView 600 can be installed.
Motor Drive Panel
The auger motor drive panel is mounted on the blender frame adjacent to the PLC control
panel in most applications. The motor drive panel is permanently wired on the blender. The
standard panel contains Yaskawa GPD 205 variable frequency motor drives, a power supply
and manual volumetric backup system wiring components.
The motor drives on the blender are standard, off the shelf drives and are readily available
from Yaskawa distributors and the manufacturer.
Power cords to each drive motor are equipped with plugs to facilitate auger removal and
motor replacement, if necessary.
Optional “Quick Color Change” Kit
The optional “QCC” quick color changeover kit allows the virgin material to be gravity fed
so the processing machine can be operated, while a color change is being done.
The virgin material auger metering assembly is equipped with a lower slide gate and
discharge tube. A flexible hose connects the discharge tube with a cast aluminum flange
below the blender that is equipped with an angled inlet tube stub. When the slide gate is
opened, virgin pellets will gravity feed to the bottom of the blender and bypass the blender
augers and the lower mass flow weigh hopper, allowing the extruder to be operated.
The blender augers can then be removed and the colors changed without the processing
machine having to be “re-strung”, and the product having to be re-gauged.
Continuous Loss-in-Weight Blenders Chapter 2: Functional Description 18
2-4 Options
The following is a list of options, which your blender may have been equipped with:
• Mezzanine stand with slide gate and 4” tube stub.
• Low-level proximity switches. Detects material supply shortages for each
supply hopper before blender runs out (Requires a separate, remote mount alarm
panel with its own lights, horn and silence button).
• Supply hopper lids for non-ACS supplied vacuum receivers & loaders.
• Agitated, straight wall regrind supply & weigh hoppers for regrind material.
• Compressed air loader for low percentage additives.
• Ethernet communication module
•
Remote Display
Allows control of blender from a second location up to 50 feet (15 meters) away. The remote
display can be located in another location to allow the blender to be operated from that
position. The additional
remote PanelView 600 operates identically to the main display.
