500TPD Test Paper Machine for Paper Mill
The test paper machine uses three air-cushion headboxes that ensure uniform fiber distribution across the full width for each layer. The test paper machine features a triple-wire forming section with a long bottom wire, a top wire, and a middle wire, plus full-ceramic dewatering elements for superior sheet formation and water removal. The test paper machine’s press section uses a four-roll three-nip design with large-diameter rolls to achieve high sheet dryness, reducing steam consumption in the dryer section. The test paper machine has an extensive dryer section with 37 drying cylinders and 6 VAC cylinders arranged in groups for efficient drying. The test paper machine also includes a sizing machine, calendering machine, and reel drum-type reeling machine with automatic roll change. The whole test paper machine is driven by AC variable frequency sectional drives that provide precise speed control and load sharing.
The test paper machine is built with high-quality components for reliable, long-term operation. This test paper machine uses stainless steel cladding on all stock-contacting parts for corrosion resistance. The test paper machine features full-ceramic dewatering elements from Shandong Guiyuan or Fujian Tianhe for excellent wear resistance. The test paper machine’s press section uses imported NSK bearings on large-diameter rolls and LYC or ZWZ bearings on other rolls. The test paper machine’s dryer section uses cast iron drying cylinders with VAC cylinders for stable sheet support. The test paper machine includes DST doctor blades from Suzhou Shizuoka for effective roll cleaning. The test paper machine is backed by a quality guarantee and responsive technical support.
