In a waste paper pulping line, pulping is the critical initial step that determines the quality of fiber separation and the load on downstream processing. Mid-consistency hydrapulpers occupy a pivotal position within the family of hydrapulpers; operating at consistencies typically ranging from 5% to 8%, they strike a balance between pulping efficiency and the need to preserve fiber integrity.
Fiber preservation: Relies primarily on friction and shear forces; pulp strength increases by 20%–35%, while energy consumption drops by 30%–40%.
Impurity integrity: Lightweight impurities remain intact rather than breaking apart, facilitating subsequent screening and reject removal.
Optimized rotor: Features double-helix or hybrid vanes that combine suction and cleaning actions to prevent screen plate clogging.
Controllable clearance: The gap between the rotor and screen plate is 3–5 mm; it is adjustable and replaceable, ensuring stable pulp discharge.
Flexible operation: Continuous mode (equipped with a pulp level tank) or batch mode (simple structural design) available.
Compact design: Vertical, enclosed, and splash-proof; easy to maintain; compatible with permanent magnet motors.
Broad raw material adaptability: Suitable for market pulp, waste paper, and broke; consistency can be adjusted based on the specific raw material.
The mid-consistency hydrapulper is a practical choice that strikes a reasonable balance between pulping quality, fiber retention, and operational cost-effectiveness.
