Indonesia’s largest MDF manufacturer, Sumatera Prima Fibreboard (SPF), headquartered in Jakarta, has entered the particleboard business by purchasing a complete CEBRO particleboard and Super Particleboard (Super PB) plant from DIEFFENBACHER for its site in Indralaya, about 28 km south of Palembang, the provincial capital of South Sumatra.
SPF’s order includes glue preparation and dosing, gluing, forming station and forming line, a CPS+ continuous press system and a raw board handling system. In keeping with DIEFFENBACHER’s smart plant concept CEBRO, the order also includes the latest MAIER flaking and milling equipment: three new MAIER Knife Ring Flakers type MRZ 1500 PLUS with FlowOptimizer, the fully automatic MAIER Knife Ring Maintenance Center and two MAIER Impact Mills.
“After this year’s Ligna trade fair, I visited DIEFFENBACHER’s headquarters in Eppingen to get a first-hand look at the new MAIER Knife Ring Flaker and the MAIER Knife Ring Maintenance Center,” says Michael Pribadi, Operational Director at SPF. “The Knife Ring Flaker is an impressive machine whose high performance is immediately apparent.Together with the Knife Ring Maintenance Center, we’ve invested in cutting-edge technology that will put us at the forefront of technological advances in flake processing and help us achieve operational excellence,” he adds.
The new MAIER Knife Ring Flaker type MRZ 1500 PLUS stands out for its compact footprint and high performance, thanks to 3D material distribution via the FlowOptimizer and an extra-wide knife ring. Its modern design features improved maintenance, adjustability and operation. The automated Heavy Particle Separator, with its easy and precise adjustment of separation efficiency, enables improved material cleaning. The main performance parameters are monitored and recorded in real-time.
The MAIER Knife Ring Maintenance Center ensures effective maintenance of knife rings. The automated multimodular system enables quick resharpening and precise adjustment of flaker knife rings with various diameters and cutting geometries. The system measures, cleans and disassembles the knife packages before analyzing the knives’ wear and either sharpening or replacing them. After adjustment, the knife packages are remounted in the knife ring. The essential parameters per knife ring are checked and recorded. The wear and setting data are collected in a database to further optimize the board properties with a positive impact on board quality and production costs.
The new complete plant order continues SPF’s relationship with DIEFFENBACHER. In 2017, SPF replaced the old sifters in its first MDF line with a Z-Sifter from DIEFFENBACHER. “The results were amazing. Not only did we reach our goal to improve board quality, but we were also able to tremendously reduce the specific energy consumption,” says Steven Widjaja, who’s responsible for corporate planning and logistics at SPF. In 2020, SPF replaced the sifter in its second MDF line with a DIEFFENBACHER Z-Sifter. “As a result, energy consumption in the sifter area went down by 50%, saving 8,000 kWh daily. At the same time, the amount of reject fibers decreased by almost 75%, and board quality improved so much that the share of boards that don’t need manual inspection increased from 60% to over 80%,” Widjaja reports.
The new complete CEBRO particleboard and Super PB plant from DIEFFENBACHER launches SPF into the particleboard market with an annual capacity of 478,500 m³. Assembly in Indralaya has begun, with commissioning planned for the end of 2026.
