Austria-headed international technology group Andritz AG has announced that it has received an order from Dezhou Taiding New Material Science and Technology Co., Ltd. (Dezhou Taiding) to supply a P-RC APMP (Pre-Conditioning Refiner Chemical Alkaline Peroxide Mechanical Pulp) fiberline with a capacity of 400 tonnes per day to the pulp and paper mill in Dezhou, Shandong, China.
According to a statement, the new system will process poplar as raw material, and the fiber produced will be used on the company’s own paper machines for printing and writing (P&W) paper and board grades. Start-up for the new fiberline, the value of which has not been disclosed, is scheduled for the third quarter of 2020.
Founded in 1998, Dezhou Taiding New Material Science and Technology Co., Ltd is a joint-stock company serving the pulp production, papermaking, and thermo-electricity business. Numerous successful references for the Andritz P-RC APMP systems worldwide were decisive in Dezhou Taiding placing the order with the company.
Andritz’s scope of supply includes the key components for the entire mechanical fiberline, ranging from chip washing to the reject treatment system. Engineering, training, supervision of the mechanical installation, commissioning and start-up are also part of the scope.
The Andritz MSD 400 Impressafiner ensures a high degree of chip delamination and thus contributes to uniform bulk density and optimal removal of moisture and extractives. The excellent material maceration and partial fiber delamination results in superior preconditions for chip impregnation, enabling maximum uptake of chemicals.
Pre-bleaching of chips, as well as high-consistency refining by the Andritz single-disc refiner S2070, will significantly improve pulp quality and keep the volume of shives as low as possible.
The S2070 operates with a narrow and stable refining gap, which is especially important when producing P&W and board grades because enhanced fiber surface and efficient fibrillation have a considerable impact on fiber bonding. The swing-door refiner design ensures a fast and easy change of refiner plates to save maintenance costs.
