◆ Pre-design speed: 180m/min, sizing roller diameter 268mm

◆ Sizing roller surface marked with special mesh. Hard chrome plating treatment, uniform sizing, less pulp consumption. 

◆ The rotation of the sizing roll is controlled by the variable frequency motor and frequency converter, which ensures that the line speed of the sizing roll is synchronized with the double-sided machine, and can be operated independently. 

◆ Electric adjustment of digital sizing or manual adjustment of sizing. ◆ Paper roller adopts pneumatic lifting, the gap is fine-tuned by electric. 

◆ Automatic circulation slurry supply, can effectively control the sizing amount, avoid slurry water precipitation, ensure good slurry water and save slurry water. 

◆ Can choose the press roller pressure or elastic pressure rod pressure.
