By applying the dehydration principle of double wedge-shaped wires, the dewatering filter plate and double pressing roll unit combine together to dewater. The length of nip and pressure difference are increased gradually, which results in the high thickening ratio and the stable outlet consistency kept between 28~35%.
The wire speed can be adjusted automatically so that the dewatering amount and outlet consistency can also be adjusted. All of these ensure the stable outlet consistency. It can be used in producing all kinds of stock such as waste paper stock, chemical pulp and mechanical pulp.The two dewatering section consists of twinwire wedged forming dewatering filter plate and double pressing roll unit. Its creative structure
