Does the Choice of Feed Phosphate
Affect Pelleting Behaviour?
Increasing numbers of animal feed compounders have commented
that the choice of feed phosphates can have an effect on pelleting
in terms of energy consumption, die wear and pellet quality. In
order to investigate this, Tessenderlo Group recently
commissioned a trial at the Research Institute of Feed Technology
(IFF, Germany) to study the effect of two different feed phosphates
on the pelleting process.
Trial set-up
The trial included two different levels of conditioning using
saturated steam; high (> 3%) and low (< 1%) moisture
addition. Also the effect of pre- and post-grinding was
studied. Pellets were produced using a ring-die press with a
3 x 60 mm die. Trial mixtures were composed of commonly
used feed ingredients, including either DCP or MCP at
practical inclusions levels. The trial mixture with MCP also
included additional limestone to balance the Ca content (see
table 1).

Results
Temperature increase (figure 1, next page)
The temperature increase due to friction in the die was
highly affected by conditioning. At high conditioning (> 3%
moisture addition) temperature increase was clearly lower.
The increase in temperature of the trial mixture including
MCP was slightly higher compared to the mixture including
DCP. This would suggest an increase in friction at pelleting.
Specific energy demand (figure 2, next page)
In addition to the effect of conditioning and grinding the
inclusion of feed phosphates increased energy consumption
compared to the control.

However, the type of phosphate (DCP or MCP) in the feed
has a clear effect on energy demand. The use of MCP
tends to create a higher energy demand under all
conditions in this trial.
Increases in energy consumption due to higher friction in
the die will ultimately lead to increased die wear.
Pellet stability (figure 3, next page)
At maximum conditioning and pre-grinding the pellet
quality (abrasion) improved with the use of DCP. When
MCP is included the quality deteriorates slightly. In the
case of post-grinding the pellet quality with MCP is hardly
improved, although the energy consumption is increased.
In all cases the hardness of the pellet is improved with the
mixtures including feed phosphates. There is, however,
hardly any difference between DCP and MCP.
This is Tessenderlo Group’s 8th newsletter
“Talking FEED ingredients”. A large part of this
issue is devoted to our new range of protected and
coated products of Sila replacing the Soda product
range. There is also a report of a pelleting trial in
which the pelleting behaviour of DCP and MCP are
compared. On page 4 the new Customer Services
Team for the Inorganics Business Unit is
introduced to you.

expertise in encapsulation. A new plant was build in 1999
capable of producing high technological and competitively

Main products in this range are the micro-encapsulated
organic and inorganic acids, combined in some cases with
natural extracts (essential oils). Products are always
coated in a way that they by-pass the stomach and have
their main effect along the whole digestive tract of the
animals.

Conclusion
This trial clearly shows that the use of MCP instead of DCP
results in a higher energy consumption when producing
pelleted feed. With the combination of high conditioning and
pre-grinding the specific energy input was 35% higher with
MCP compared to DCP. In spite of this higher energy
consumption the pellet quality is not improved, using MCP.
Conditioning and grinding also have an influence on
pelleting expressed in terms of energy consumption and
pellet quality. In general, conditioning with saturated steam
results in a lower energy consumption and better pellet
quality. Post-grinding shows improvements in production
and pellet quality compared to pre-grinding.
DCP and MCP are two very distinct feed phosphates: DCP
is a powdered product with a neutral pH, MCP being more
an acidic and granulated product. These chemical and
physical differences may account for the differences
observed during pelleting.

Tessenderlo Group launches new Customer
Services Team for its Inorganics Business Unit
As part of our continuing drive to improve the relationship with our customers, Tessenderlo Group has been
in the process of re-organizing its supply chain. One of the outcomes of this project is the creation of a new
centralized Customer Services Team under the direction of John Kraft, based at our site in Tessenderlo
(Belgium). The Team became operational at the beginning of July.
The new Customer Services Team for the Inorganics Business
Unit is led by Ariane Goovaerts and is made up of Customer
Service Representatives (CSRs) who handle the complete endto-end order process, from customer order intake right through
to shipment and invoicing. This change gives the CSRs
complete control over the whole order processing chain,
ensuring that our customers can be quickly updated on the
progress of their orders.
The CSRs are now at your disposal to handle order intakes,
transport booking and call-offs, invoicing and all order-related
questions. Each CSR has responsibility for a portfolio of clients
and products, which are shown in the table below. Naturally, all
commercial topics, such as pricing and sales conditions, will
remain the responsibility of your Sales Manager.
Clients in Spain, Italy, Germany, Holland and the UK and
Ireland should continue to contact their respective local offices
in Madrid (TC España); Cologna Veneta (Italphos); Hamburg
(HGS); Rotterdam (TCR) and Leeds (Britphos) for all enquiries
st
related to order processing. From the 1 of March however,
customers in Spain and the UK should also directly contact the
Customer Services Team in Tessenderlo (Belgium).
Information will be sent to inform you further on this change.
“The centralized coordinates will help ensure all orders
receive immediate attention even in the absence of your
regular CSR. In addition, all orders received via these
coordinates will be automatically archived in case of queries
at a later date,” explains John Kraft.
“When using these new coordinates, we guarantee that your
order will be handled immediately. You are therefore
requested not to use the old telephone and fax numbers
from now on, otherwise you may find that your order is not
processed. You are, of course, free to copy communications
sent to the central coordinates to your regular CSR and
Sales Manager if you feel that this is necessary.”
“Tessenderlo Group is convinced that working with
dedicated Customer Service Representatives will strengthen
our co-operation. Your help in ensuring a smooth transition
is greatly appreciated.”
