1. The contaminants are removed without being pulverized to improve the fining operation. 2. The high-consistency processing facilitates the after-treatment process. 3. Small reject ratio scales lower than the tail screen. 4. The attached cleaner could take the place of the high-consistency cleaner. 5. Automatic reject discharge does not require manpower. Operation Description： 1. The standard consistency at inlet is 3% ~ 4%. However, the consistency can be raised up 5%. 2. The standard inlet pressure and drop pressure are 1.5 ~ 2.0kg/c㎡ and 0.3 ~ 0.7 kg/c㎡ respectively. 3. The standard diameters of holes on the strainer are 2 to 3 mm for waste newspaper and magazines are 3.5 to 4.5mm for waste corrugated boards. However, the actual size varies according to the machines before and after the separator. 4. The reject ratio is 3% to 7%, which varies in accordance with the kind of waste paper. The standard material for the wetted part is SUS304 or its equivalent.
