For a longer durability, we recommend using a rotor with knives made of hardmetal tungsten carbide instead of the standard rotor made of tool steel.

In the beginning of the grinding process, a moving of the pusher of the standard funnel has been hindered lightly. After 2 minutes of grinding, pusher could be operated without any obstacles.

During the grinding process, fine sample dust escaped the standard funnel. Placing a tube of a vacuum cleaner next to the funnels opening avoids dust exploration.

To avoid dust exploration, the optional sample exhauster system with cyclone separator can be used. This way, sample pusher does not need to be used and grinding time will be shortened because of the high air flow which will remove ground sample after it is able to pass the sieve cassettes openings.

Within the first 90 seconds of grinding, an output of 110 g of ground sample has been found inside of the collecting vessel. After a total of 2 minutes, output rose to 123 g; after 3 minutes of grinding, 140 g of sample have been found. After a total of 5 minutes, the desired amount of 150 g of sample has been found.

About 5 g of sample use to lie loose inside of the grinding chamber. Most pre ground residues will be found on top of the sieve cassette and in front of the first fixed knife.

Cleaning can be done rapidly by vacuuming with a soft brush.
