ANDRITZ Reject Compactor ReCo
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 rejects from recycled fiber lines. It is designed to obtain highest dryness levels. The final dryness depends on the reject material (especially the fiber content) and the press settings selected.
The Reject Compactor ReCo is available in three 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%
- Both types, ReCo-C and ReCo-F, can reach final drynesses of up to 70%
- ReCo-L: light design with smaller capacities for fibrous rejects and/or consistencies as low as 0.8%; discharge consistency up to 35%
ANDRITZ Granulator UG
Shredding is a core unit operation in any reject treatment system and sets the correct particle size for the subsequent process steps, such as fine metal separation or optical sorting.
The ANDRITZ fine shredder UG is designed for treating pulp and paper rejects that typically contain a large amount of heavy particles. Due to its rigid design, such contaminants pose no risk for operation of the machine. The UG has a high-speed, single-shaft rotor with special hardened knives. Screen plates with various hole diameters determine the final particle size.
