Slotted Baskets

As a leader in stock preparation equipment manufacturing, Parason has been developing profiled wedge bar baskets for the last few decades. Parason baskets efficiently remove dirt, specks & stickies to improve properties like cleanliness, strength, brightness, whiteness, and printability of paper.

Applications

Parason screen baskets are developed for use in stock preparation, broke system, pulp mill, and approach flow screening for Parason screens and for all existing non Parason screens and associated rotor combinations of other manufactures.

Continuous improvement in our manufacturing methods yields the highest precision in different Slotted designs and roundness of the screen baskets. Each screen goes through a hard-chrome process to improve wear resistance property for a better life.

Re-Chrome Plating Of Screen Baskets

Extend the lifetime of your screen basket with our re-chroming and repair services. Rebuilding your existing rotors provides substantial cost-saving benefits as well as the possibility of upgrading older OEM rotors to newer more productive and energy-efficient designs for today’s demanding screening applications. PARASON also offers screen bearing assembly and housing rebuilds.

Screen rebuilds and upgrades are available for virtually all OEM makes and models.

To regain profile geometry

Due to operational wear in screening, the heads of profile bars frequently wear out. Rebuilding the chrome layer ensures constantly high screening quality.

PARASON team is specially trained in the analysis of screen baskets so as to be able to determine whether re-chroming is necessary. If so, the old chrome layer of the screen basket is completely removed. It is especially ensured that there is no change in the geometry of the profile head comes. The slot width of the screen basket also remains unchanged.

Chrome is one of the materials that are least susceptible to wear and can also be applied repeatedly. This makes re-chroming the most economical alternative for wear prevention in the case of screen baskets. Re-chroming is provided for the entire screen basket portfolio from PARASON and for those of other manufacturers. The service is also specifically available for hole screen baskets.
