A reject separator is a type of paper recycling equipment used to separate unwanted materials, or rejects, from the paper pulp in a recycling process. It is typically used after the pulping process, where the paper is broken down into fibers.
The reject separator works by using centrifugal force to separate the rejects from the pulp. The pulp is fed into the machine and passes through a series of rotating blades, which create a vortex that separates the heavier rejects from the lighter pulp fibers. The rejects are then discharged from the machine, while the clean pulp is sent to the next stage of the recycling process.
The rejects that are removed by the separator can include any non-paper materials that may have made their way into the recycling process, such as plastic or metal contaminants. Removing these contaminants is important for ensuring the quality of the recycled paper, as well as for preventing damage to downstream equipment.
Reject separators are commonly used in paper mills and other recycling facilities that process large volumes of paper. They are an important part of the recycling process, helping to improve efficiency and reduce waste.
