Description:

Voith Size 12 Combisorter Screen

Combisorter CSM

High throughput rates and low wear

The Combisorter CSM efficiently screens in recovered paper stock preparation for medium consistency. It provides for rejects that are virtually free of fibers and consumes little energy at high throughput rates.

 

The Combisorter CSM is suitable for processing inlet stock consistencies up to 3% and rejects dry content up to 30%. Due to the basalt-lined housing and the downstream cleaner at the heavies outlet, wear is minimized. In addition, the cleaner separates the rejects into light and heavy fractions. Simple control is possible through inlet pressure regulation.

The Combisorter CSM is suitable for use in recovered paper stock preparation for medium consistency screening. It can be used as the final stage in holed screening or as an intermediate screen in combined and slotted screening.

 
 The Combisorter™ is a coarse tailing screen that is capable of deflaking stock while simultaneously cleaning and dewatering impurities from recovered fiber systems. Centrifugal forces created from the vortex in the lower housing will cause heavyweight particles to move outwards and rotate against the inlet chamber walls. If not routinely inspected, the wear resistant lining (basalt tile) of the lower housing will over-abrade and heavyweight particles will wear through the stainless steel exterior of the housing. Loss of production and increased fiber loss will result.
 
 Importance of rotor blade, extraction plate and orifice plate The disk rotor sweeps the extraction plate and contributes a rotational flow (together with the tangential flow of stock into the inlet chamber) that produces a vortex and, with it, a radial pressure gradient in the lower housing. At the top of the inlet chamber is an orifice plate with an opening in its center that enables the lower chamber to be pressurized. The fiber and contaminants retained above the extraction plate enter the core of the vortex, pass through the orifice plate and into the upper zone for further screening.
 
 The Combisorter™ upper housing assembly contains components that significantly impact the separation of fibers from contaminants and the dewatering and transportation of rejects out of the machine. As the components in the upper housing wear, their washing and rejects conveying attributes deminish resulting in decreased production and increased fiber loss.
 
The Combisorter has a lower screening and deflaking section and an upper washing, screening, dewatering and conveying section. The disk rotor blade in the lower section clears the extraction plate of debris, preventing contaminants from plugging the extraction holes and, in combination with the surfaces of the stationary extraction plate, provides the attritionzone necessary for the deflaking of undefibered furnish. The disk rotor also contributes to a rotational flow (together with the tangential flow of stock into the inlet chamber) that produces a vortex and, with it, a radial pressure gradient in the lower housing.
