1
Introduction
WARNING: Improper installation, operation, or servic-
ing may result in equipment damage or personal
injury.
This equipment should be installed, adjusted, and serviced by qualified technical
personnel who are familiar with the construction, operation, and potential hazards
of this type of machine.
All wiring, disconnects, and fuses should be installed by qualified electrical techni-
cians in accordance with electrical codes in your region. Always maintain a safe
ground. Do not operate the equipment at power levels other than what is specified
on the machine serial tag and data plate.
WARNING: Voltage hazard
This equipment is powered by single-phase alternating current, as specified on
the machine serial tag and data plate.
A properly sized conductive ground wire from the incoming power supply must be
connected to the chassis ground terminal inside the electrical enclosure. Improper
grounding can result in severe personal injury and erratic machine operation. (120
Volt units come with a grounded plug. Must be plugged into a grounded out.)
Always disconnect and lock out the incoming main power source before opening
the electrical enclosure or performing non-standard operating procedures, such as
routine maintenance. Only qualified personnel should perform troubleshooting pro-
cedures that require access to the electrical enclosure while power is on.
CAUTION: Mix blade hazard
There are two hazards associated with the mix blades. First, the blades are driven
with substantial torque. Never place your hand in the mix chamber unless power
is completely disconnected. Second, the mix blades may become razor sharp.
Always be careful when touching or cleaning these blades. Check for sharp edges
frequently. Replace blade if a hazard exists.
CAUTION: Vertical valve hazard
Vertical valves in hoppers slam closed without warning. They will injure your fin-
gers. Always keep fingers clear of valve openings. Never use your fingers to clear
an obstruction. Never use your fingers to move a sticking valve.
(Continued)

1-4 l Introduction
CAUTION: Slide gate hazard
Never use your fingers to move a sticking slide gate under the mix chamber.
CAUTION: Misuse hazard
This blender must be exclusively used for metering and mixing free-flowing (as per DIN
ISO 3435) plastic granulate and additives. A total of four to six different materials can be
metered and mixed in the blender, depending on model.
The following must not be metered and mixed:
Foods of all types (unit does not meet hygienic standards).
Highly abrasive materials, such as stones, sand (increased wear of unit components).
Poorly free flowing, sticky materials (airtight seal by the pneumatic cylinder is adversely
affected).
Liquids and powders (airtight seal by the pneumatic cylinder is not possible).

1-6 l Introduction
Zero Mechanical State (ZMS)
CAUTION: Before performing maintenance or repairs on this product, you should
disconnect and lockout electrical power sources to prevent injury from unexpected
energization or start-up. A lockable device has been provided to isolate this prod-
uct from potentially hazardous electricity.
During maintenance, it is essential that the system be put into a state which eliminates the
possibility of components making an unexpected and dangerous movement. This procedure
is typically referred to as lockout. After all energy sources have been neutralized, the system
is in the zero mechanical state (ZMS). This provides maximum protection against unexpect-
ed mechanical movement.
The lockout procedure must include all energy sources:
Electrical power supply
Compressed air supply
Hydraulic fluids under pressure
Potential energy from suspended parts
Energy in springs
Any other source that might cause unexpected mechanical movement
The following is a recommended Zero Mechanical State procedure which must be followed
prior to any inspection, adjustment or maintenance of the system.
1If there is a remote control device, press the <STOP> key at that remote operator’s
control.
2Press the <STOP> key at the local TrueBlend SB-4 control panel.
3Disconnect and lock out the primary electrical supply feeding the TrueBlend SB-4
controller.
4Disconnect and lock out the primary electrical supply feeding the material handling
system that is feeding the TrueBlend SB-4 material hoppers with process material.
5Shut-off and lock out the primary compressed air supply that is feeding the
material handling devices. Vent the compressed air supply lines.
6On each TrueBlend SB-4, disconnect all of the cables leading to the motor of the
metering device. (Where applicable).
7Drain any process material from the loading devices feeding the TrueBlend SB-4
material hoppers.
8Lock out all energy sources which might cause unexpected movement of equip-
ment which is accessible through the discharge at the base of the TrueBlend SB-4
extruder hopper.
9Test to verify that all energy sources have actually been disconnected and/or de-
energized.
WARNING: Before removing lockout devices and returning switches to the ON
position, make sure that all personnel are clear of the machine, tools have been
removed, and all safety guards reinstalled.

What is the TrueBlend SB-4 Blender?
The TrueBlend SB-4 Blender is a precision gain-in-weight gravimetric batch blender. The
ability to precisely control the material blend improves overall quality and reduces material
cost. Faster, automated start-up helps create more quality product and generates less scrap.
The TrueBlend SB-4 Blender automatically adjusts for variations in material type, density,
and geometry.
Typical Applications
1Unit mounted directly on the processing machine.
2Unit operated as a centralized mixing station. If used as a centralized mixing station, a
frame with reservoir hopper and exhaust box is available. The frame can be bolted to the
floor.

How It Works: The TrueBlend
The TrueBlend Blender meters and mixes free-flowing plastic granulate (regrind and natural
material) and additives. The unit mixes four to six materials, depending on model and con-
figuration. The unit meters each ingredient into a gain-in-weight material batch hoppers
with mounting flanges for one hopper loader each. All components are dispensed by pneu-
matic vertical cone valves and are fed into the weigh bin, which is mounted on a load cell.
The pneumatic cylinder opens the weigh bin. The mixture (batch) falls into the mixing
chamber and is mixed and agitated by an electrically powered mixer into a homogeneous
state. The mixing chamber holds three batches. After mixing, the chamber is emptied by
the discharge slide gate into the injection or extrusion process.
Next, the vertical valves
dispense the pro-
grammed amount of
material into the weigh
bin.
The load cell deter-
mines when the batch
is complete, and the
pneumatic cylinder
drops the batch into
the mixing chamber.

The batch is mixed by
the electrically powered
mixer.

The discharge slide
gate is opened and the
mixture is emptied.
Note: After the slide gate discharges the mixture, approximately one batch remains in the mixing
chamber to ensure that the next batch can be optimally mixed.

TrueBlend SB-4 System Components
The TrueBlend SB-4 Blender is comprised of a number of separate components, each hav-
ing a specific function, as described below:
TrueBlend SB-4 Controller – This is the overall “brain” of the system. An easy-to-use
intuitive touch screen controller with full color graphics allows quick and easy set-up.
User friendly screens are configurable to match each specific injection or extrusion
process. Simple menu driven touch screens ask all appropriate questions for ease of indi-
vidual application set-up. The operator enters the blend recipe here. The operator can
also monitor the blender control set points, current and past alarm status and complete
management of material inventory data.
Recipe Entry Modes
Depending upon the control mode selected, there are several recipes entry options. The
available recipe entry options determine how an operator would enter that data needed to
control the blender. Simple menu driven touch screens ask all appropriate questions for ease
of product recipe set-up.
The recipe entry options available are configured from the ‘Setup’ screen. From the Home
Screen, press More/Setup/System/Recipe. From this screen you select whether your recipe
is an Injection format (allows Naturals, Regrinds, Additive Naturals and Additive Batch
recipe entry), or Extrusion format (allows Natural and Regrind recipe entry).
Resin and Product Names
Resin names are used to identify the various resins included in the products. There can be up
to 250 different resin names entered and each name can be comprised of a 10-character
alphanumeric name. The TrueBlend SB-4 controller will keep inventory totals for each
resin name defined.
Product names are used to identify the various production recipes of the products to be
made. There can be up to 1000 different product name recipes and each name can be com-
prised of a 12-character alphanumeric name. The TrueBlend SB-4 controller will keep a
complete inventory for each of the product names.
The use of the resin and product names is optional and must be enabled or disabled from the
recipe set-up menu screen. From the Home Screen, press More/Setup/System/Recipe.
From this screen you set Use Resin Names to ‘YES’. If this is enabled, names must be in
the recipes, from the Recipe screen.

SPECIFICATION NOTES
* Maximum throughput rates are based on 35 lb/ft3pel-
letized material, using all standard valve sizes. Use of
reducer inserts will lower the rate shown.
Throughput rates are based on:
• A 4-position blender recipe of 20% regrind, 80%
natural, 3% color and 2% additive material.
†The optional flow control valve will mount inside the
chassis in the space of the manual slide valve. Conair
recommends using the optional flow control valve when
mounting the blender on a stand, surge bin or hopper.
‡Hopper positions three and four are supplied with
eight inch cover plates as standard.
§ Numbers in top view drawings represent hopper posi-
tions.
Specifications may change without notice consult with a
Conair representative for the most current information.
