APTMP LINE 250 tpd

Producer: Andritz
Capacity: 90,000 ton per Annum (250 tpd)
Use Case:
- Alkaline peroxide thermomechanical pulping（APTMP）add caustic soda, hydrogen peroxide, and stabilizers to soften and brighten wood chips prior to refining in a disc refiner.
- The chip pretreatment facility uses a screw feeder device to apply mechanical compression on wood chips and squeezed out the detrimental substances for bleaching.
- The facility also partially destroys wood matrix of chips allowing for easier fiber separation and reduced refining energy.
Advantages:
- The APTMP (Alkaline Peroxide Thermal Mechanical Pulp) process technology has advantages over the conventional TMP and CTMP processes.
- It can be operated with little wastewater (i.e. almost closed water cycle) and requires significantly less energy input.
- The wood pulp produced is characterized by high strength and high whiteness as well as good drainage. This enables energy reduction on the paper machine.
Current Status:
- The equipment consists of new parts, reconditioned used parts and non-remanufactured parts (such as disc filters, scrubbers and steam heat exchangers).
- The system never went into operation and was never fully assembled. It is complete, dismantled and stored on factory premises.
Included:
- In addition, there are system components for storing wood chips as well as the conveyor technology for feeding a wood chip silo and the corresponding discharge system.
