Blenders - GRAVIMAX - Gravimetric Dosing
Very Simple Operation
The user-friendly multi-task control is menu driven providing:
- Percent preset - ingredient values entered in % desired
- Display operating conditions
- Material identification data base
- Recipe storage
- Preset batch count
- Miscellaneous reports
Unique Metering Pinch Valves
- Dispense major and minor ingredients
- Each valve consists of a sleeve and pinch bars which are not affected by the types of plastics processed, such as abrasive, dusty or irregular shaped materials
- Extremely fast, efficient and reliable, these pinch valves precisely meter each material to the desired set point consistently
Fast Clean Out Feature Reduces Downtime
- Large removable access window
- Removable safety doors with quick release latches
- Easily removable scale hopper for access to mixing chamber
- Removable mixing paddle and stainless steel liner for efficient cleaning
RTLS Technology
A unique 3-stage metering method achieves the most precise dispensing for batch-tobatch
consistency and accuracy. This is accomplished by using progressively smaller
dispensing algorithms to approach the target weight. Only one standard high precision
valve is used for pellets, regrind and powder.
Material Savings Reduce Cost
Batch-to-batch accuracy means no overuse of high cost resins, optimizing the material
consumption for the product requirement. Every batch is consistent and to the desired
formula. No 'hunting' or statistical averaging to achieve the required target.
Where do the savings
come from?
By ensuring batch-to-batch accuracy by
means of RTLS (Real Time Live Scale) technology
the operator can set the percentages to
the required minimum level. As competitive
blending methods are constantly overdosing
and underdosing the minimum needs to be
set to allow any underdosed batch to still
be at the requested percentage. This results
in overdosing all other batches, sometimes
even significantly, causing tremendous excess
material usage. RTLS can pay for itself in just
a couple of months!
WITTMANN's Blender Control - Designed for Simplicity, Ease-of-Use and High Efficiency
The large easy-to-see buttons on the touch screen make it easy
to operate in all types of light conditions and ensures the operator
has a large surface area to make changes or adjustments in the
operation of the blender.
