Advantages of the AMANDUS KAHL Machines
for the Chemical Industry
owdery additives are used in many sectors
of the chemical industry. The handling
of these sometimes very dusty, often
poorly flowing and partly explosive materials
is a great challenge for many users. By
means of agglomeration by compression of
the powdery components, many problems
in handling these products can be solved
and production processes can be simplified
and made safer. Numerous polymer additive
mixtures have been compacted and stabilized
in this way for many years in order
to meet the constantly growing demands of
the polymer industry.
AMANDUS KAHL designs and manufacP
tures
machines and plants for the processing
of powdery products such as inorganic
fertilizers, minerals, detergents, detergent
additives, master batches and precisely
these polymer additives as single components
or One-Packs. The focus here is particularly
on pelleting presses. By processing
polymer additives with AMANDUS KAHL
pelleting presses, handling and use of the
additives in polymer refinement or compounding
can be optimized.
The KAHL machines for use in the chemical
industry are characterised by a multitude
of design advantages. The large press
interior and a product supply by gravity
allow high feeding rates without the need
for a force feeding device. The KAHL hydraulic
system with automatic roller gap monitoring
also ensures a safe process control.
The low circumferential speed of the pan
grinder rollers results in smooth and lowvibration
press operation, a long service
life of the rollers and roller bearings as well
as a low operating noise of approx. 70 dBA.
The tailor-made design of the machines allows
a versatile adaptation of the pelleting
process to the requirements of the product.
Depending on the specific needs, the
machines can be manufactured in stainless
steel, dust-tight flanged, in dust-ex design
or with inerting. The large variety of possible
designs of pelleting tools also permits
the processing of temperature-sensitive
products or those with a high lubricant
agent content.
A fast die and tool change enables an
almost uninterrupted production run and a
Optimize calibrations
Putting data to work by optimizing calibration
intervals
A
chieving the correct balance between too much calibration
and too little is a challenge for anyone reliant on critical measurements.
Many companies follow a static interval approach and
calibrate once a year during scheduled downtimes. This fixed calibration
interval selection is a typical illustration of established but
outdated rules.
Ideally, calibration intervals should be chosen to reflect an acceptable
risk that the measurement error has not drifted outside
of an acceptable range. Considering common practice, this is seldom
the case. Often calibration intervals are set to one year for the
sake of convenience as it aligns well with annual planning cycles.
However, calibration intervals should be optimized to find the best
trade-off between cost and risk.
Using established existing statistical methods as a base,
Endress+Hauser has developed an enhanced method for calibration
interval optimization. With Calibration Interval Optimization
Endress+Hauser has developed a service that delivers more than a
calculated result. Significant interval changes are discussed, and
all underlying assumptions validated together with the customers.
Intervals are then included as one of a number of operational constraints
including downtime availability to deliver a fully optimized
calibration execution schedule. In the end, the customer benefits
from an overall reduction of both cost and risk.
This scientific model has been proven across +22 billion calibrations
and considers past calibration results to predict future behavior
with the following main results:
high flexibility of the machines when changing
products. Remote maintenance and a
KAHL service team on site ensure excellent
support even after commissioning.
With more than 140 years of experience
in the design and manufacture of machines
and plants for the processing and pelleting
of a wide range of products for different
industries, AMANDUS KAHL has acquired
a very good international reputation.
Machines and plants are characterized by
quality " made in Germany " . Are you interested

* 67% of current calibration intervals could be significantly
increased
* only 20% of instruments are set up with an optimal calibration
interval
* time operating out of tolerance can be reduce by 46% compared
to a static approach
Calibration Interval Optimization uses a proven scientific model to
determine intervals between calibrations.
It includes:
* Determination of optimal calibration intervals using innovative
methods
* Consultancy provided by metrology experts
* Alignment to, and application of intervals according to operational
constraints
The benefits:
* Reduction of calibration costs due to extended calibration
intervals
* Reduced out of tolerance risk as calibration intervals are reduced
