ANDRITZ Reject Compactor ReCo

Dewatering of rejects to highest dryness

Rejects from recycled fiber lines are quite wet when they leave the process, with a lot of free water and water stored in the fibrous material. While free water is relatively easy to remove, the water in the fibers is more critical. Considerable force is needed to achieve an acceptable dry content in the material. However, the higher reject consistencies also help save on drying and disposal costs.

The Reject Compactor ReCo is a robust screw press for dewatering fiber-containing rejects and is available in several versions, each tailored to specific types of reject material:

ReCo-C is designed for coarse rejects with a high plastic content and higher consistency, typically from drum pulping and conventional pulping systems.
ReCo-F is ideal for finer rejects with high fiber content and low consistency, such as those from fine screening and DAF systems.
ReCo-B
ReCo450 is a high-performance manure dewatering solution optimized for dairy farm operations.

Reject Compactor ReCo-C – Dewatering of rejects from recycled fiber lines

Reject Compactor ReCo-F – Dewatering of fine rejects

Typical coarse rejects are:

Pieces of plastic and plastic films
Undissolved paper, wood, textiles
Stones, pieces of metal

Typical fine rejects are:

Fibers, stickies, wax
Sand, glass, small pieces of metal

ANDRITZ Reject Compactor

The Reject Compactor ReCo is available in several different models:

ReCo-C: for coarse pulping rejects with higher consistencies, typically 10-45%
ReCo-F: for fine rejects with higher fiber content and consistencies down to 1.5%
ReCo-B:
ReCo450: the output moisture remains below 60% and delivers a output of 6.25 t/h.
ReCo-L: light design with small capacities and/or consistencies as low as 0.8%; discharge consistency up to 35%
