A scraper 2 rotates on the sieve 5 with a changeable speed. A scraper 2 rotates on the sieve 5 with a changeable speed. A compass-type shutter, with a changeable port, is mounted under the sieve 5, and a precision balance 20 is mounted below the shutter 6. An electronic computer 30 is programmed for checking and con trolling the rotation speed of the scraper 2, the opening/closing of the shutter 6 and the weight value of the balance 20.
