The
EXAKT E Series combines the flexible technologies of production mills with
state-of-the-art control and programming. All in a compact size, ideal for lab
or pilot plant.
A unique, feature-rich, electronically controlled three roll mill that
brings impressive new levels of operation and flexibility to bench-top
formulating. The highly sophisticated control features normally found
only on the most up-to-date production mills can now be used in product
development, pilot plant projects and small production runs. The remarkable
new EXAKT 80E offers exceptional operational flexibility as well as providing
outstanding reliability and repeatability. And, the EXAKT E Series is operator-friendly.
All E Series models meet or exceed the safety requirements specified in ANSI.
E-Model
features:
Unique Dual Mode Gap Control
- The EXAKT E models allow you to control the gap between the rollers (and thus
the dispersion qualities) in two modes
- Gap mode - A quantitative setting to a specific gap value (in microns)
- Force mode - A quantitative setting to a specific line pressure in
the gap (in Newtons/mm)
- The gaps are continuously monitored and adjusted by the control system to
maintain the pre-set value which also provides continuous, automatic roller alignment
- The gaps can be independently set to simultaneously operate in either mode
with independent monitoring and control in the mode selected
- The operator can change the mode of gap control during operation
Programmability and Scale-up
The electronic control package has several levels of features
- Operational parameters can be stored in 99 discreet programs including sub-programs
for products requiring multiple process runs
- Parameters that can be set are roller speed and gap settings (in either mode)
- The control system will default to last program run on the mill when the main
power supply is turned on.
- RS 232/USB interface capability (optional) providing Data Logging etc.
- The operator control panel provides real-time operational displays in both
operating modes that translate to larger volume production conditions (scale-up)
- In gap mode setting, the user-defined gap setting and the actual force
value are displayed
- In force mode the user-defined force value and both the actual (corresponding)
gap and force values are displayed
New Levels of Safety
Incorporated into the EXAKT E Series are new safety features for bench-top mills:
Cleaning mode – the mill defaults to the maximum gap spacing and minimum
torque.
Reverse roller direction - once stopped by either the emergency stop system
or during normal operation, the direction of the rollers can be reversed. Once
activated, movement in the reverse direction is controlled in steps until the
foreign object can be removed from between the rollers.
Emergency stop function - in the event of emergency stop activation, the rollers
are automatically opened to the widest possible gap.
The EXAKT E Series was specifically designed for manufacturers who need extraordinary
precision and control of particle dispersion in small quantities. In applications
that range from color blending in printing inks and cosmetics to nano-particle
dispersion for electronics, the EXAKT E Series provides a means of achieving
extremely precise particle size reduction/dispersion in a remarkably reproducible
format. Product development, pilot plant projects, small production runs
- only the EXAKT E Series offers you the flexibility, precision and control
that fit your requirements.
Roller materials available with the E Series are hard-chrome-plated steel,
aluminum oxide, zirconium oxide, silicon carbide and tungsten carbide coated steel.
All models are equipped with the EXAKT universal scraper system. This
system allows a cost-effective and rapid exchange of scraper
knives. The steel, plastic and ceramic scraper knives offered by EXAKT
can be easily substituted based on specific product requirements.
All models are fully equipped with the following components:
- Cooling and heating capability in the roller system
- Stainless steel hopper
- Universal scraper system
- Splash tray to facilitate cleaning
Options:
- PFA Coating on scraper aprons and hoppers
- Datalog software
- Pressurized heating/cooling of rollers (120 EH - 250 & 450)
- Additional safety stops
