FeedMax – Improved screw feeder concept

A screw feeder upgraded with a FeedMax provides uniform feeding, optimized dewatering and therefore reduced energy consumption. Consequently, this concept is the optimal answer for upgrading our customers’ various processes.

Why is choosing correctly so important?
Different processes have different require­ments. In some processes dewatering is the most important parameter, while in other applications very uniform feeding is essen­tial. The main factors that can be influenced by choice can be summarized as follows:

• capacity
• energy consumption
• feeding stability
• lifetime
• dewatering.

Benefits
One or more benefits can be attained depending on the application:

• Improved dewatering
• Increased liquid absorption during impregnation
• Increased brightness using less chemicals as a result of improved washing
• More uniform and stable feeding of chips or pulp, which stabilizes the load on the refiner
• Longer lifetime.

Applications
This type of upgrade is suitable for ADI, SFA and PDA screw feeders in the following positions:

• Preheater feeding
• Impregnator feeding
• Refiner feeding
