17/02/2017: Van Aarsen introduces new feeding device for its GD hammer mill

Innovative ATEX-certified grinding installation to minimise explosion risk in fish feed manufacturing process

Employees, production equipment, and buildings are all incredibly valuable assets. By minimising the required maintenance and maximising the service life of expensive grinding installations, it’s also possible to ensure that they are much more cost-effective.

In order to further minimise explosion risk, Van Aarsen has introduced an innovative feeding device with an integrated heavy parts separator (also known as a “stone catcher”) for its GD hammer mill.

When dust comes into contact with an ignition source, such as sparks, in an oxygen rich environment, there is a risk of explosion, and that is exactly what happens when the grinding process for grains and organic materials is started or stopped in a hammer mill.

Van Aarsen develops and manufactures machines for the production of compound feeds and premixes for the animal feed industry. It is also a leader in developing new techniques for minimising explosion risk without compromising the efficiency and quality of the grinding process.

As such, Van Aarsen has now introduced an innovative feeding device with an integrated heavy parts separator for metal objects, stones, and other heavy objects. The heavy parts separator detects such objects and removes them to prevent them from being fed into the hammer mill and causing sparks.

Van Aarsen has optimised its heavy parts separator by automating the removal of metal objects and stones and by the combination of this removal with the screen exchange process.

By ensuring that the automated removal of heavy objects and the exchange of the screens take place at the same time, the downtime of the hammer mill is reduced and its capacity is increased.

In order to provide a controlled release of pressure in case of an explosion, van Aarsen has also fitted the bin beneath the hammer mill with a pressure relief valve.
