Dog Food

In this trial we used our Variable Speed Rotor Mill PULVERISETTE 14 premium line converted into a cutting mill in combination with our high-performance cyclone separator and 4 mm square hole perforated sieve shells. We programmed the maximum speed setting of 18000 rpm for this trial.

We took a batch of 200 g of the dog food. The sample was fed slowly and was ground within 1:40 minutes. The grinding sound was typical during the grinding process. Afterwards we checked the grinding chamber. No perforations were clogged, but it could be seen that the sample was very greasy and gradually adhered to the sieve pan holder and the collecting vessel.

We packed the sample and cleaned the Variable Speed Rotor Mill PULVERISETTE 14 premium line equipment with a soft brush and hot water.

In this trial, we used our Knife Mill PULVERISETTE 11, which was equipped with standard grinding vessel made of plastic PC and a standard knife made of stainless steel. We programmed the grinding time into 3 steps, 2 x 5 seconds with 5000 rpm for pre-crushing and 1 x 10 seconds with 10000 rpm. We took 200 g of the dog food again. After the grinding time of 20 seconds we checked the collecting vessel. The majority of the sample was ground much finer than the requested 1 mm. Like in our first trial, the surfaces which were in contact with the ground sample, were covered with a small amount of the grease or oil.
