Screening machines optimize the quality of lignin by removing impurities and dust, classifying lignin pellets by size and eliminating lumps.
Lignin is the second most common biopolymer on earth after cellulose. In the industrial processing of wood, especially in paper production, lignin is produced in large quantities as a by-product. In the past, this by-product was often burned to generate energy, but due to its chemical structure and properties, it is now used as a filler, additive, binder, reinforcing agent or adsorbent. The use of lignin in these and other applications is in line with the trend towards the bioeconomy, in which renewable, plant-based raw materials are used instead of fossil resources.
Screening machines help improve the quality of the produced lignin and prepare it for specific applications or further processing steps:
The best choice of a screening machine for lignin depends on the specific requirements of the process, including desired particle size, throughput, material properties and other specific criteria. The following factors should be considered when processing lignin:
The RHEsono® screening machine from RHEWUM is extremely suitable for screening and, in particular, dedusting of lignin pellets. Its direct drive technology allows the finest particles to be effectively separated from the main product, while the automatic cleaning system ensures that the screening mesh does not become clogged even during intensive operation. RHEWUM screening machines thus ensure the quality and homogeneity of the pellets, which is essential for downstream industrial applications and processes.
