Open Area Calculation
Constant advances in our manufacturing methods yield the highest precision in different hole designs and roundness of the screen baskets. Each screen goes through a hard-chrome process for wear resistance quality which increases basket life.

Up to any standard required size | MOC: Sheet: SS316, Support ring :SS304 | We perform 100% inspection of each basket. 100% QC product | Surface Finish – Electro Polishing, Hard Chrome Plating (Plating thickness from 100 microns to 400 microns) |
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 manufacturers.
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.
Application Based Wedge Bar Designs
Parason has developed different wedge wires considering a wide range of screen basket applications as per:
- Open area requirement
- Slot size
- Strength
- Fiber length

The wavy & serrated wear causes maximum fiber damage and multiple disadvantages of high power consumption, increased cost per tonne, load variations, etc. PARASON has innovated the concept of `ERP’ that is Edge Retention Property. During strenuous refining conditions, the ‘ERP’ plate has flat wear.
Casting is done by using the latest technology to provide the best condition for the alloys in temperature, time, melting technique to determine the best suitable alloy. Due consideration to properties of erosion, corrosion, wear resistance of refiner plates is taken care of.
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.
