Benefits and features
- Less internal pressure drop leading to more vacuum applied to pulp mat
- Higher discharge consistency
- Improved washing efficiency
- Higher dilution factor
- Anti-rewet ability
- Increased filtrate capacity
- Improved reliability
At today‘s high production rates, many vacuum washers are operating over design capacity. When drum replacement becomes necessary, the ANDRITZ MaxFlo™* drum is the latest in vacuum washer technology. With a high capacity antirewet deck, reinforced structural components, and an optimized hydraulic design, the MaxFlo drum maximizes efficiency and reliability. With the ability to be retrofitted into nearly any OEM washer system, the MaxFlo drum is the ideal solution in both brownstock and bleaching applications.
Driving force in vacuum washers is vacuum that is created by barometric leg. Pressure loss in drum end, channels and drum deck is direct loss in vacuum. Optimizing each critical component for minimum loss will lead to higher capacity drum and even vacuum along the drum length. This means minimizing the losses:
The new ANDRITZ vacuum washer drum is a result of comprehensive R&D work that focused on improved fluid hydrodynamics and cost-effective construction. As the result we have generated a modular designed drum with higher ROI:
