Dewatering presses and screens are essential pieces of equipment in the paper recycling industry. They are used to remove excess water and other contaminants from the recycled paper pulp before it is further processed into new paper products.
Dewatering screens work by using a series of rotating screens with varying sizes of holes or slots that allow water to pass through while trapping larger contaminants. The screens are positioned at an angle so that the pulp is forced to move along the length of the screen while the water drains away. The resulting pulp is more concentrated and can be further processed to remove additional contaminants.
Dewatering presses work by using hydraulic pressure to squeeze the pulp between two plates or rollers. This forces the water out of the pulp and into collection channels while retaining the pulp solids. The resulting pulp cake can be easily transported and further processed.
Both dewatering presses and screens are available in a variety of sizes and configurations to meet the specific needs of different paper recycling facilities. They are typically used in combination with other equipment, such as shredders and pulpers, to create a complete recycling system.
