In the machine, at the commencement of the operation, foreign solid matter is removed simultaneously with the pre-washing of the waste. The unwanted matter is flushed through openings in the processing vessel, and the sepg. process is concluded by covering or reducing the size of the openings. The waste is then washed again and cut up. Troublesome foreign matter such as stones, wood, textiles, etc. is removed at the start before it is reduced in size.</p> |
