Definitions
- the invention relates to a separating device for separating grinding media and ground suspension in a wet grinding machine, with a sieve arranged at the grinding material outlet of the wet grinding machine, the passage openings of which are designed with dimensions that block the passage of grinding media.
- the invention is therefore based on the object of providing a separating device which, in the above suspensions, enables the ground suspension to be separated from the grinding media without producing excessive flow resistance at the separating device, which in turn means longer service lives of the wet comminution machine and simpler and therefore less expensive designs of the agitator mill has the consequence.
- vibrations preferably ultrasound
- the vibrator is attached on the one hand to the separating device and on the other hand to the housing of the wet shredding system.
- ground suspension and grinding media 2 are located in the interior of a grinding chamber 1 of an agitator mill.
- the ground suspension leaves the grinding chamber via the grinding material outlet opening 3.
- a flat screen 4 designed as a slotted sieve is arranged, the gap widths of which are approximately 1/3 of the grinding media diameter.
- a vibrator 5 is coupled to the flat screen.
- a seal 6 prevents suspension from flowing out of the feed point of the vibrator through the grinding chamber housing 7.
- the flat screen In order to prevent the flat screen from becoming blocked, it is set in a vibrating motion by the vibrator during operation of the agitator mill. Experiments have shown that abraded and broken grinding media and small product particles in the flat sieve settle far less during the vibrating movement and that it has a considerably longer service life.
