On pulp and paper production lines, the pulp screening equipment drum screen is a piece of equipment that, despite its seemingly simple structure, plays a critical role. Installed downstream of the pulper or hydrapurger, drum screen is specifically designed to process rejects, thoroughly separating materials such as plastic film, foam, and light impurities from usable fibers.
Simple structure, reliable operation
Composed of a horizontal cylindrical screen drum, machine body, drive assembly, and spray cleaning system. Pulp moves axially; accepted pulp passes through the screen holes/slots, while coarse impurities are discharged through the reject outlet at the end. With few potential points of failure, it is well-suited for continuous production.
Low-speed rotation, significant energy savings
Operates at speeds of only a few to just over a dozen revolutions per minute. It does not rely on high-speed hydraulic pulses, resulting in low power consumption, smooth operation, and low noise levels—offering distinct energy-saving advantages in coarse screening reject handling.
Minimal fragmentation of impurities
Low-speed, gentle transport prevents light impurities—such as plastic films, foam blocks, and fibrous debris—from breaking apart, facilitating their subsequent separation and removal; this makes it particularly suitable for waste paper pulping systems.
Continuous operation with robust anti-clogging and cleaning capabilities
Equipped with spray water curtains, axially reciprocating cleaning pipes, or doctor blade mechanisms to minimize clogging from fibrous debris and ensure continuous, stable operation in the screening zone.
Easy maintenance, predictable wear patterns
Routine checks focus on bearing lubrication and the wear of support rollers and the screen drum. Since wear is concentrated in specific areas, components can be replaced or wear-resistant liners added as needed, keeping maintenance costs under control.
