Rejects from a pulper are not always completely free of usable fiber. Sending this material straight to disposal can mean losing recoverable pulp, while returning it untreated may bring troublesome contaminants back into the process. A Reject Separator provides a dedicated step between pulping and reject handling. Inside the machine, mechanical agitation loosens fiber still attached to the residue. Recovered pulp passes through the screening openings and returns to the stock system, while larger unwanted materials are retained and conveyed toward the reject discharge.

 

Designed for the demanding conditions of waste paper processing, Leizhan’s Reject Separator combines a durable casing, screening components and a drive system suited to continuous operation. Its action helps handle mixed coarse rejects—including plastic pieces, textiles, wire and incompletely pulped paper—without treating every contaminant as recoverable stock. The separator can be selected to fit the mill’s reject volume and process arrangement, and access for inspection and maintenance supports routine upkeep. Operating results depend on the incoming reject composition and the selected screen configuration.
