Coarsepressure Screen

The coarse pressure screen is a vital machine for pulp screening and purification in the paper pulp stock preparation process. Designed to eliminate large impurities and unqualified fibers, it performs preliminary screening to deliver cleaner and more refined pulp for subsequent processing.

This screen utilizes an upward flow design, where pulp enters from the bottom and flows upward along the inner wall of the screen drum. The specialized screen mesh filters out acceptable pulp, while larger impurities are isolated and discharged. The equipment’s pressure regulation system ensures optimal flow for effective and consistent screening performance.

• Efficient Impurity Removal: Separates heavy impurities to protect the rotor and screen basket from excessive wear.

• Improved Screening Efficiency: Upward flow design increases pulp contact with the screen mesh for better separation.

• Gentle Fiber Handling: Breaks paper pieces mildly, avoiding further fragmentation of impurities.

• Durable Design: The rotating cylinder design extends the lifespan of the contour surface.

• Optimized Pressure Control: Maintains appropriate pressure for effective pulp flow and screening performance.

• Versatile Application: Ideal for coarse screening of waste paper stock in pulp preparation systems.
