Key Applications & Capacities:

Primary Knotter Screening – Efficient removal of knots from sulfite, softwood, and groundwood pulping processes. Capacity: Up to 170 metric tons per day (187 short tons per day)

Knot Draining System – Works in conjunction with a pressure knotter to recover long fibers while rejecting relatively dry knots. Capacity: Up to 120 metric TPD (132 short TPD)

Bull Screening – Coarse screening for groundwood and knotting applications, reducing fiber loss while removing unwanted slivers and coarse waste. Capacity: Up to 250 metric TPD (275 short TPD)

Fine Virgin Fiber Tailings – Processes tailings from virgin pulp screening systems, delivering fiber-free rejects for further processing. Capacity: Up to 55 metric TPD (61 short TPD)

Reject Thickening – Efficient thickening of reject stock at 10-15% consistency in pulp mill refining systems. Capacity: Up to 20 metric TPD (22 short TPD)

Primary Coarse Screening for Secondary Fiber (Deinking) – Removes rubber, plastics, and contaminants from high-consistency (3.5%) secondary fiber stock. Capacity: Up to 170 metric TPD (187 short TPD)

Final Tailings Screening – Handles rejects from primary pressure screens, producing drier rejects with high efficiency. Capacity: Up to 100 metric TPD (110 short TPD)

Wastewater Scalping – Removes coarse and lightweight debris from mill wastewater, preventing system clogging. Capacity: 4,500 to 5,300 liters per minute (1,200 to 1,400 gallons per minute)

High Consistency Broke Screening – Removes large flakes and debris from high-consistency (3.5%) broke stock. Capacity: Up to 200 metric TPD (220 short TPD)

Paper Machine Fine Screen Tailings – Eliminates debris from Fourdrinier and cylinder machine vats, ensuring clean headbox operation. Capacity: 2,800 liters per minute (750 gallons per minute)
