•
Equipment
“Equipment” can mean an individual unit, a machine or an installation.
•
Operating personnel
The “operating personnel” are persons operating the equipment on their own responsibility or
according to instructions.
•
Operator
The “operator” of the equipment (production
manager, foreman, etc.) is the person responsible for all production sequences. The operator
instructs the operating personnel of what is to be
done.
•
Operating instructions
The “operating instructions” describe the interaction of the equipment, production sequences or methods. The operating instructions must be compiled by the operator of the
equipment.
•
Equipment foreman
When several operating personnel work on
one machine, the “equipment foreman” coordinates the sequences. The equipment foreman
must be appointed by the operator.
•
Trained personnel
“Trained personnel” are persons who, due to
their training, are authorized to carry out the required work.
1.3. Legal basis
See “Manufacturer’s Certificate” resp. “Certificate of Conformity”.
1.4. Fields of applications
The Ultrablend 75 is ideally suited for blending granulates, additives and regrinds.
High dosing accuracy and consistency improves end product quality and saves money by using less
additives and reducing scrap.
The Ultrablend 75 is specially designed for direct mounting on small injection molding machines and
extruders. All products are dosed and weighed one after each other into a weigh hopper supported
by a single load cell. Once all components are weighed, they are passed to the mixing chamber
where they are homogenized before exiting the blender.
64.10-0268GB02 12/03
1.5. Notes on Usage
•
Experienced operators of Ultrablend systems
can begin directly with the chapter on “Continuous Operation” if the unit has been properly installed and the initial start-up has been carried
through.
•
If the unit has not been installed yet, observe
the instructions in the chapter on “Installation
Instructions” and “Transport, Assembly and
Storage” . After the installation, carry through
the initial start-up.

Description of Functions 9-1
UB 75
9.1. Ultrablend 75
Colortronic’s gravimetric batch blender Ultrablend 75 is ideally suited for blending granulates, additives and regrinds with direct mounting on small injection molding machines, blow molding machines
and extruders.
The Ultrablend 75 is well suited to low rate extrusion applications that do not use powders or require
loss-in-weight blending technology. The blender can be mounted directly on the feed throat or on a
starve feeder.
9.1.1. Structure
The Ultrablend can be equipped with up to 4 dosing units. As an option, it is possible to equip the individual storage receptacles of the dosing units with filling level probes.
The weighing container rests on one load cell.
A horizontal blending unit is installed underneath the weighing container.
There is a filling level probe in the mixing chamber. The weighing container can be emptied only if
this filling level probe is not covered.
64.10-0268GB02 12/03
There is an option of installing a pneumatic slide valve for evacuation of the mixing chamber underneath the unit. This slide valve can be controlled by means of another filling level probe.
UB 75
9.1.2. Method of Functioning
Colortronic’s gravimetric batch blender Ultrablend 75 improves process quality and saves money
through the application of high dosing accuracy and mixing. All products are dosed and weighed one
after each other into a weigh bin supported by a single load cell. Once all components are weighed,
they are passed to the mixing chamber where they are homogenized before exiting the blender.
The Process Begins:
The process begins with the dosing hoppers filled
with material and the weigh bin and mixer empty.

A
64.10-0268GB02 12/03
Dosing of Components:
Component A is dosed into the weigh hopper first
via a slide valve. The amount of material dosed is
controlled by the recipe and batch weight. Once
the correct amount of Component A is dosed, then
Component B is dosed in the weigh bin on top of
Component A. This process continues until all
components, up to four, are dosed.
UB 75
Mixing Begins:
Once all the components are dosed into the weigh
bin properly, the dump valve opens and discharges the weigh bin contents into the mix hopper. The mixer combines the individual components into one homogenous mix.
64.10-0268GB02 12/03
Dosing and Mixing:
The dosing cycle begins again while the mixing
continues until the high level point in the mix hopper is reached. At this point the process stops.
The process will restart when the processing machinery below takes material from the mix hopper
and the material level drops below the low level.
UB 75
9.2. Control System
The control system is a controller for the central operation of maximally 6 dosing units.
9.2.1. Switch Cabinet (E-Box)
The switch cabinet is attached to the housing of the Ultrablend. It contains the control units and optional control extensions.
9.3. Refilling System (Optional)
A refilling system makes it possible to fully automate the filling of the material hoppers. The material
is automatically refilled in combination with a conveyor unit.
64.10-0268GB02 12/03
As conveyor units, Colortronic single conveyor units as well as Colortronic multiple conveyor units
can be used. By means of a universal flange, an existing conveying system can be assembled as
well.

11. Service Settings
Version: 64.10-0266GB02 12/03
F
All service settings have already been carried through ex works and normally do not have to be changed.
Service settings may only be modified if the factory settings are too general
for special requirements.
Service settings may only be altered on consultation with the Colortronic
service since these settings are of decisive importance for the operational
safety of the device.
Precise knowledge of the control, the dosing process, the mechanics of the
device and of processing machines are required for entering service settings.
Ensure in each case that the staff are informed.
Service settings cannot be changed during automatic operation.

Parts The sum of all components is irrelevant, all materials are equivalent, the control calculates automatically
the percentage of each component.
New material = 100
Materials from the dosing units “Regenerat“ are understood by the control as already dosed material. Raw material and additive together must add up to 100 %.
Material to be ground + new material = 100
The sum of all components must be 100 %.
Regrind Correction
Select the material correction in the case of faulty dosing:
None = no correction
Direkt = more material àmore new material,
the ratio material to be ground to new material remains
about the same.
64.10-0266GB02 12/03
Invers = more material à less new material,
the batch weight remains about the same.
