Guide to Selecting and Avoiding Pitfalls for Sizing Machine

If you’re still selecting sizing machines based on “it runs,” you could be bleeding 8% to 15% of your annual profit without knowing it. Traditional sizing machine procurement focuses on the purchase price while ignoring three hidden cost drivers: Raw material waste comes from uneven coating that forces overuse of starch or AKD. Energy black holes emerge from poorly designed roll configurations that guzzle steam. Downtime penalties accumulate through frequent breaks and cleaning cycles that steal production hours.

Solution Approach for Leizhan Sizing Machine

1. Leizhan sizing machines deploy variable-frequency metering rod systems with optional grooved roll or smooth roll configurations. PLC closed-loop control delivers: Coating weight accuracy within ±1.5% versus industry-standard ±5%. Cross-machine profile adjustment response under 30 seconds. Stable operation across the full speed range of 60 to 800 meters per minute.
2. Uneven cross-machine profiles plague domestic size presses. Leizhan engineers solved this with curved inlet distributors paired with adjustable weir plates.
   Turbulence intensity inside the pond drops 40%, cutting air entrainment and flocculation. Edge recirculation control eliminates the “heavy edge” syndrome common in conventional designs. Removable end covers reduce cleaning and maintenance time by 60%.
3. Post-sizing drying consumes 25% to 35% of total steam demand in most paper mills. Leizhan’s intelligent temperature control system automatically adjusts steam pressure to cylinder groups based on actual coating weight. Optimized drying curves prevent over-drying or wet streaks. Heat recovery interfaces come standard, ready for integration into mill-wide thermal systems.

If you are planning a new paper production line or upgrading your existing sizing system, please contact us. Provide three parameters: paper type, basis weight, and production speed.
