In 2009, Kadant published a study presenting the characterization and removal strategy of small stickies, referred to as ministickies in our study. One of the conclusions, based on mill surveys and several pilot plant trials, was that the screening efficiency of ministickies is low and some technologies were better than others for removing ministickies. Since that initial study, a 4th generation of screening cylinders has been introduced to the market.
The capabilities of an on-line condition monitoring system have been embedded in a distributed control system (DCS) which uses common I/O hardware, signal processing hardware and software, engineering configuration tools, information trending and alarming. Machine operators and a maintenance staff are now able to see quickly developing vibration and process pulsation problems and determine their causes, using a unified user interface which is combined with process control functions of the DCS.
Metso's OptiLayer coater is a multilayer, slide die curtain coater which provides excellent coating coverage. Since multiple coating layers can be applied simultaneously,with essentially no speed restrictions, it is possible to fine tune each coating layer for specific paper properties. The technology, jointly developed by Metso and Dow Chemical, has been used for specialty paper grades and white top liner grades and also offers an economical substitute for coated board applications where air knife coaters have conventionally been used. Another suitable application is food packaging board.
The Siemens Industry Solutions Division (IS) installed a membrane bioreactor plant with downstream reverse osmosis for wastewater treatment at Albert Köhler GmbH & Co. KG in Gengenbach, Germany. The system enables almost all the process water to be reused and reduces the volume of wastewater by some 90 per cent.
ANDRITZ is well-regarded for its portfolio of washing systems.
To create a durable and reliable product, ANDRITZ designed the Wash Press AWP with a minimum number of components. The Wash Press AWP has a compact and innovative design that sets a new standard for performance.
The unique drum design and simple component structure require little maintenance and contribute to a long mechanical life. These features, together with low power consumption, result in a highly capable wash press with a low total cost of ownership.
